docs/put_key: add tutorial that explains how to manage global platform keys

With the increased interest in using GlobalPlatform features of
UICC and eUICCs (OTA-SMS, applets, etc.), also comes an increased
interest in how the related GlobalPlatform keys can be managed
(key rotation, adding/removing keysets from/to a Security Domain).

Unfortunately, many aspects of this topic are not immediately
obvious for the average user. Let's add a tutorial that contains
some practical examples to shine some light on the topic.

+Guide: Installing JAVA-card applets
+===================================
+
+Almost all modern-day UICC cards have some form of JAVA-card / Sim-Toolkit support, which allows the installation
+of customer specific JAVA-card applets. The installation of JAVA-card applets is usually done via the standardized
+GlobalPlatform (GPC_SPE_034) ISD (Issuer Security Domain) application interface during the card provisioning process.
+(it is also possible to load JAVA-card applets in field via OTA-SMS, but that is beyond the scope of this guide). In
+this guide we will go through the individual steps that are required to load JAVA-card applet onto an UICC card.
+
+
+Preparation
+~~~~~~~~~~~
+
+In this example we will install the CAP file HelloSTK_09122024.cap [1] on an sysmoISIM-SJA2 card. Since the interface
+is standardized, the exact card model does not matter.
+
+The example applet makes use of the STK (Sim-Toolkit), so we must supply STK installation parameters. Those
+parameters are supplied in the form of a hexstring and should be provided by the applet manufacturer. The available
+parameters and their exact encoding is specified in ETSI TS 102 226, section 8.2.1.3.2.1. The installation of
+HelloSTK_09122024.cap [1], will require the following STK installation parameters: "010001001505000000000000000000000000"
+
+During the installation, we also have to set a memory quota for the volatile and for the non volatile card memory.
+Those values also should be provided by the applet manufacturer. In this example, we will allow 255 bytes of volatile
+memory and 255 bytes of non volatile memory to be consumed by the applet.
+
+To install JAVA-card applets, one must be in the possession of the key material belonging to the card. The keys are
+usually provided by the card manufacturer. The following example will use the following keyset:
+
++---------+----------------------------------+
+| Keyname | Keyvalue                         |

+| DEK/KIK | 5524F4BECFE96FB63FC29D6BAAC6058B |

+| ENC/KIC | 542C37A6043679F2F9F71116418B1CD5 |

+| MAC/KID | 34F11BAC8E5390B57F4E601372339E3C |
++---------+----------------------------------+
+

+
+
+Applet Installation
+~~~~~~~~~~~~~~~~~~~
+
+To prepare the installation, a secure channel to the ISD must be established first:
+
+::
+
+    pySIM-shell (00:MF)> select ADF.ISD
+    {
+        "application_id": "a000000003000000",
+	"proprietary_data": {
+	    "maximum_length_of_data_field_in_command_message": 255
+        }
+    }
+    pySIM-shell (00:MF/ADF.ISD)> establish_scp02 --key-dek 5524F4BECFE96FB63FC29D6BAAC6058B --key-enc 542C37A6043679F2F9F71116418B1CD5 --key-mac 34F11BAC8E5390B57F4E601372339E3C --security-level 1
+    Successfully established a SCP02[01] secure channel
+
+.. warning:: In case you get an "EXCEPTION of type 'ValueError' occurred with message: card cryptogram doesn't match" error message, it is very likely that there is a problem with the key material. The card may lock the ISD access after a certain amount of failed tries. Carefully check the key material any try again.
+
+
+When the secure channel is established, we are ready to install the applet. The installation normally is a multi step
+procedure, where the loading of an executable load file is announced first, then loaded and then installed in a final
+step. The pySim-shell command ``install_cap`` automatically takes care of those three steps.
+
+::
+
+    pySIM-shell (SCP02[01]:00:MF/ADF.ISD)> install_cap /home/user/HelloSTK_09122024.cap --install-parameters-non-volatile-memory-quota 255 --install-parameters-volatile-memory-quota 255 --install-parameters-stk 010001001505000000000000000000000000
+    loading cap file: /home/user/HelloSTK_09122024.cap ...
+    parameters:
+     security-domain-aid: a000000003000000
+     load-file: 569 bytes
+     load-file-aid: d07002ca44
+     module-aid: d07002ca44900101
+     application-aid: d07002ca44900101
+     install-parameters: c900ef1cc80200ffc70200ffca12010001001505000000000000000000000000
+    step #1: install for load...
+    step #2: load...
+    Loaded a total of 573 bytes in 3 blocks. Don't forget install_for_install (and make selectable) now!
+    step #3: install_for_install (and make selectable)...
+    done.
+
+The applet is now installed on the card. We can now quit pySim-shell and remove the card from the reader and test the
+applet in a mobile phone. There should be a new STK application with one menu entry shown, that will greet the user
+when pressed.
+
+
+Applet Removal
+~~~~~~~~~~~~~~
+
+To remove the applet, we must establish a secure channel to the ISD (see above). Then we can delete the applet using the
+``delete_card_content`` command.
+
+::
+
+    pySIM-shell (SCP02[01]:00:MF/ADF.ISD)> delete_card_content D07002CA44 --delete-related-objects
+
+The parameter "D07002CA44" is the load-file-AID of the applet. The load-file-AID is encoded in the .cap file and also
+displayed during the installation process. It is also important to note that when the applet is installed, it cannot
+be installed (under the same AID) again until it is removed.

+Retrieving card-individual keys via CardKeyProvider
+===================================================
+
+When working with a batch of cards, or more than one card in general, it
+is a lot of effort to manually retrieve the card-specific PIN (like
+ADM1) or key material (like SCP02/SCP03 keys).
+
+To increase productivity in that regard, pySim has a concept called the
+`CardKeyProvider`.  This is a generic mechanism by which different parts
+of the pySim[-shell] code can programmatically request card-specific key material
+from some data source (*provider*).
+
+For example, when you want to verify the ADM1 PIN using the `verify_adm`
+command without providing an ADM1 value yourself, pySim-shell will
+request the ADM1 value for the ICCID of the card via the
+CardKeyProvider.
+
+There can in theory be multiple different CardKeyProviders.  You can for
+example develop your own CardKeyProvider that queries some kind of
+database for the key material, or that uses a key derivation function to
+derive card-specific key material from a global master key.
+
+pySim already includes two CardKeyProvider implementations. One to retrieve
+key material from a CSV file (`CardKeyProviderCsv`) and a second one that allows
+to retrieve the key material from a PostgreSQL database (`CardKeyProviderPgsql`).
+Both implementations equally implement a column encryption scheme that allows
+to protect sensitive columns using a *transport key*
+
+
+The CardKeyProviderCsv
+----------------------
+
+The `CardKeyProviderCsv` allows you to retrieve card-individual key
+material from a CSV (comma separated value) file that is accessible to pySim.
+
+The CSV file must have the expected column names, for example `ICCID`
+and `ADM1` in case you would like to use that CSV to obtain the
+card-specific ADM1 PIN when using the `verify_adm` command.
+
+You can specify the CSV file to use via the `--csv` command-line option
+of pySim-shell.  If you do not specify a CSV file, pySim will attempt to
+open a CSV file from the default location at
+`~/.osmocom/pysim/card_data.csv`, and use that, if it exists.
+
+The `CardKeyProviderCsv` is suitable to manage small amounts of key material
+locally. However, if your card inventory is very large and the key material
+must be made available on multiple sites, the `CardKeyProviderPgsql` is the
+better option.
+
+
+The CardKeyProviderPgsql
+------------------------
+
+With the `CardKeyProviderPgsql` you can use a PostgreSQL database as storage
+medium. The implementation comes with a CSV importer tool that consumes the
+same CSV files you would normally use with the `CardKeyProviderCsv`, so you
+can just use your existing CSV files and import them into the database.
+
+
+Requirements
+^^^^^^^^^^^^
+
+The `CardKeyProviderPgsql` uses the `Psycopg` PostgreSQL database adapter
+(https://www.psycopg.org). `Psycopg` is not part of the default requirements
+of pySim-shell and must be installed separately. `Psycopg` is available as
+Python package under the name `psycopg2-binary`.
+
+
+Setting up the database
+^^^^^^^^^^^^^^^^^^^^^^^
+
+From the perspective of the database, the `CardKeyProviderPgsql` has only
+minimal requirements. You do not have to create any tables in advance. An empty
+database and at least one user that may create, alter and insert into tables is
+sufficient. However, for increased reliability and as a protection against
+incorrect operation, the `CardKeyProviderPgsql` supports a hierarchical model
+with three users (or roles):
+
+* **admin**:
+  This should be the owner of the database. It is intended to be used for
+  administrative tasks like adding new tables or adding new columns to existing
+  tables. This user should not be used to insert new data into tables or to access
+  data from within pySim-shell using the `CardKeyProviderPgsql`
+
+* **importer**:
+  This user is used when feeding new data into an existing table. It should only
+  be able to insert new rows into existing tables. It should not be used for
+  administrative tasks or to access data from within pySim-shell using the
+  `CardKeyProviderPgsql`
+
+* **reader**:
+  To access data from within pySim shell using the `CardKeyProviderPgsql` the
+  reader user is the correct one to use. This user should have no write access
+  to the database or any of the tables.
+
+
+Creating a config file
+^^^^^^^^^^^^^^^^^^^^^^
+
+The default location for the config file is `~/.osmocom/pysim/card_data_pgsql.cfg`
+The file uses `yaml` syntax and should look like the example below:
+
+::
+
+   host: "127.0.0.1"
+   db_name: "my_database"
+   table_names:
+   - "uicc_keys"
+   - "euicc_keys"
+   db_users:
+      admin:
+         name: "my_admin_user"
+         pass: "my_admin_password"
+      importer:
+         name: "my_importer_user"
+         pass: "my_importer_password"
+      reader:
+         name: "my_reader_user"
+         pass: "my_reader_password"
+
+This file is used by pySim-shell and by the importer tool. Both expect the file
+in the aforementioned location. In case you want to store the file in a
+different location you may use the `--pgsql` commandline option to provide a
+custom config file path.
+
+The hostname and the database name for the PostgreSQL database is set with the
+`host` and `db_name` fields. The field `db_users` sets the user names and
+passwords for each of the aforementioned users (or roles). In case only a single
+admin user is used, all three entries may be populated with the same user name
+and password (not recommended)
+
+The field `table_names` sets the tables that the `CardKeyProviderPgsql` shall
+use to query to locate card key data. You can set up as many tables as you
+want, `CardKeyProviderPgsql` will query them in order, one by one until a
+matching entry is found.
+
+NOTE: In case you do not want to disclose the admin and the importer credentials
+to pySim-shell you may remove those lines. pySim-shell will only require the
+`reader` entry under `db_users`.
+
+
+Using the Importer
+^^^^^^^^^^^^^^^^^^
+
+Before data can be imported, you must first create a database table. Tables
+are created with the provided importer tool, which can be found under
+`contrib/csv-to-pgsql.py`. This tool is used to create the database table and
+read the data from the provided CSV file into the database.
+
+As mentioned before, all CSV file formats that work with `CardKeyProviderCsv`
+may be used. To demonstrate how the import process works, let's assume you want
+to import a CSV file format that looks like the following example. Let's also
+assume that you didn't get the Global Platform keys from your card vendor for
+this batch of UICC cards, so your CSV file lacks the columns for those fields.
+
+::
+
+   "id","imsi","iccid","acc","pin1","puk1","pin2","puk2","ki","opc","adm1"
+   "card1","999700000000001","8900000000000000001","0001","1111","11111111","0101","01010101","11111111111111111111111111111111","11111111111111111111111111111111","11111111"
+   "card2","999700000000002","8900000000000000002","0002","2222","22222222","0202","02020202","22222222222222222222222222222222","22222222222222222222222222222222","22222222"
+   "card3","999700000000003","8900000000000000003","0003","3333","22222222","0303","03030303","33333333333333333333333333333333","33333333333333333333333333333333","33333333"
+
+Since this is your first import, the database still lacks the table. To
+instruct the importer to create a new table, you may use the `--create-table`
+option. You also have to pick an appropriate name for the table. Any name may
+be chosen as long as it contains the string `uicc_keys` or `euicc_keys`,
+depending on the type of data (`UICC` or `eUICC`) you intend to store in the
+table. The creation of the table is an administrative task and can only be done
+with the `admin` user. The `admin` user is selected using the `--admin` switch.
+
+::
+

+
+The importer has created a new table with the name `uicc_keys`. The table is
+now ready to be filled with data.

+
+A quick `SELECT * FROM uicc_keys;` at the PostgreSQL console should now display
+the contents of the CSV file you have fed into the importer.
+
+Let's now assume that with your next batch of UICC cards your vendor includes
+the Global Platform keys so your CSV format changes. It may now look like this:
+

+
+When importing data from an updated CSV format the database table also has
+to be updated. This is done using the `--update-columns` switch. Like when
+creating new tables, this operation also requires admin privileges, so the
+`--admin` switch is required again.
+
+::

+   INFO: CSV file import done, 3 rows imported
+   INFO: Changes to table uicc_keys committed!
+
+On the PostgreSQL console a `SELECT * FROM uicc_keys;` should now show the
+imported data with the added columns. All important data should now also be
+available from within pySim-shell via the `CardKeyProviderPgsql`.
+
+
+Column-Level CSV encryption
+---------------------------
+
+pySim supports column-level CSV encryption.  This feature will make sure
+that your key material is not stored in plaintext in the CSV file (or
+database).
+
+The encryption mechanism uses AES in CBC mode.  You can use any key
+length permitted by AES (128/192/256 bit).
+
+Following GSMA FS.28, the encryption works on column level.  This means
+different columns can be decrypted using different key material.  This
+means that leakage of a column encryption key for one column or set of
+columns (like a specific security domain) does not compromise various
+other keys that might be stored in other columns.
+
+You can specify column-level decryption keys using the
+`--csv-column-key` command line argument.  The syntax is
+`FIELD:AES_KEY_HEX`, for example:
+
+`pySim-shell.py --csv-column-key SCP03_ENC_ISDR:000102030405060708090a0b0c0d0e0f`
+
+In order to avoid having to repeat the column key for each and every
+column of a group of keys within a keyset, there are pre-defined column
+group aliases, which will make sure that the specified key will be used
+by all columns of the set:
+
+* `UICC_SCP02` is a group alias for `UICC_SCP02_KIC1`, `UICC_SCP02_KID1`, `UICC_SCP02_KIK1`
+* `UICC_SCP03` is a group alias for `UICC_SCP03_KIC1`, `UICC_SCP03_KID1`, `UICC_SCP03_KIK1`
+* `SCP03_ECASD` is a group alias for `SCP03_ENC_ECASD`, `SCP03_MAC_ECASD`, `SCP03_DEK_ECASD`
+* `SCP03_ISDA` is a group alias for `SCP03_ENC_ISDA`, `SCP03_MAC_ISDA`, `SCP03_DEK_ISDA`
+* `SCP03_ISDR` is a group alias for `SCP03_ENC_ISDR`, `SCP03_MAC_ISDR`, `SCP03_DEK_ISDR`
+
+NOTE: When using `CardKeyProviderPqsl`, the input CSV files must be encrypted
+before import.
+
+Field naming
+------------
+
+* For look-up of UICC/SIM/USIM/ISIM or eSIM profile specific key
+  material, pySim uses the `ICCID` field as lookup key.
+
+* For look-up of eUICC specific key material (like SCP03 keys for the
+  ISD-R, ECASD), pySim uses the `EID` field as lookup key.
+
+As soon as the CardKeyProvider finds a line (row) in your CSV file
+(or database) where the ICCID or EID match, it looks for the column containing
+the requested data.
+
+
+ADM PIN
+~~~~~~~
+
+The `verify_adm` command will attempt to look up the `ADM1` column
+indexed by the ICCID of the SIM/UICC.
+
+
+SCP02 / SCP03
+~~~~~~~~~~~~~
+
+SCP02 and SCP03 each use key triplets consisting if ENC, MAC and DEK
+keys.  For more details, see the applicable GlobalPlatform
+specifications.
+
+If you do not want to manually enter the key material for each specific
+card as arguments to the `establish_scp02` or `establish_scp03`
+commands, you can make use of the `--key-provider-suffix` option.  pySim
+uses this suffix to compose the column names for the CardKeyProvider as
+follows.
+
+* `SCP02_ENC_` + suffix for the SCP02 ciphering key
+* `SCP02_MAC_` + suffix for the SCP02 MAC key
+* `SCP02_DEK_` + suffix for the SCP02 DEK key
+* `SCP03_ENC_` + suffix for the SCP03 ciphering key
+* `SCP03_MAC_` + suffix for the SCP03 MAC key
+* `SCP03_DEK_` + suffix for the SCP03 DEK key
+
+So for example, if you are using a command like `establish_scp03
+--key-provider-suffix ISDR`, then the column names for the key material
+look-up are `SCP03_ENC_ISDR`, `SCP03_MAC_ISDR` and `SCP03_DEK_ISDR`,
+respectively.
+
+The identifier used for look-up is determined by the definition of the
+Security Domain.  For example, the eUICC ISD-R and ECASD will use the EID
+of the eUICC.  On the other hand, the ISD-P of an eSIM or the ISD of an
+UICC will use the ICCID.

 ~~~~~~~~~~~~~~~~~~~~~~~~~
 Two modes are possible:
 
-  - one where you specify every parameter manually :
+  - one where the user specifies every parameter manually:
 
-``./pySim-prog.py -n 26C3 -c 49 -x 262 -y 42 -i <IMSI> -s <ICCID>``
+    This is the most common way to use ``pySim-prog``. The user will specify all relevant parameters directly via the
+    commandline. A typical commandline would look like this:
+
+    ``pySim-prog.py -p <pcsc_reader> --ki <ki_value> --opc <opc_value> --mcc <mcc_value> --mnc <mnc_value>
+    --country <country_code> --imsi <imsi_value> --iccid <iccid_value> --pin-adm <adm_pin>``
+
+    Please note, that this already lengthy commandline still only contains the most common card parameters. For a full
+    list of all possible parameters, use the ``--help`` option of ``pySim-prog``. It is also important to mention
+    that not all parameters are supported by all card types. In particular, very simple programmable SIM cards will only
+    support a very basic set of parameters, such as MCC, MNC, IMSI and KI values.
+
+  - one where the parameters are generated from a minimal set:
+
+    It is also possible to leave the generation of certain parameters to ``pySim-prog``. This is in particular helpful
+    when a large number of cards should be initialized with randomly generated key material.
+
+    ``pySim-prog.py -p <pcsc_reader> --mcc <mcc_value> --mnc <mnc_value> --secret <random_secret> --num <card_number> --pin-adm <adm_pin>``
+
+    The parameter ``--secret`` specifies a random seed that is used to generate the card individual parameters. (IMSI).
+    The secret should contain enough randomness to avoid conflicts. It is also recommended to store the secret safely,
+    in case cards have to be re-generated or the current card batch has to be extended later. For security reasons, the
+    key material, which is also card individual, will not be derived from the random seed. Instead a new random set of
+    Ki and OPc will be generated during each programming cycle. This means fresh keys are generated, even when the
+    ``--num`` remains unchanged.
+
+    The parameter ``--num`` specifies a card individual number. This number will be managed into the random seed so that
+    it serves as an identifier for a particular set of randomly generated parameters.
+
+    In the example above the parameters ``--mcc``, and ``--mnc`` are specified as well, since they identify the GSM
+    network where the cards should operate in, it is absolutely required to keep them static. ``pySim-prog`` will use
+    those parameters to generate a valid IMSI that thas the specified MCC/MNC at the beginning and a random tail.
+
+Specifying the card type:
+
+``pySim-prog`` usually autodetects the card type. In case auto detection does not work, it is possible to specify
+the parameter ``--type``. The following card types are supported:
+
+ * Fairwaves-SIM
+ * fakemagicsim
+ * gialersim
+ * grcardsim
+ * magicsim
+ * OpenCells-SIM
+ * supersim
+ * sysmoISIM-SJA2
+ * sysmoISIM-SJA5
+ * sysmosim-gr1
+ * sysmoSIM-GR2
+ * sysmoUSIM-SJS1
+ * Wavemobile-SIM
+
+Specifying the card reader:
+
+It is most common to use ``pySim-prog`` together with a PCSC reader. The PCSC reader number is specified via the
+``--pcsc-device`` or ``-p`` option. However, other reader types (such as serial readers and modems) are supported. Use
+the ``--help`` option of ``pySim-prog`` for more information.

+Card programming using CSV files
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-``./pySim-prog.py -n 26C3 -c 49 -x 262 -y 42 -z <random_string_of_choice> -j <card_num>``
+To simplify the card programming process, ``pySim-prog`` also allows to read
+the card parameters from a CSV file. When a CSV file is used as input, the
+user does not have to craft an individual commandline for each card. Instead
+all card related parameters are automatically drawn from the CSV file.
 
-    With <random_string_of_choice> and <card_num>, the soft will generate
-    'predictable' IMSI and ICCID, so make sure you choose them so as not to
-    conflict with anyone. (for eg. your name as <random_string_of_choice> and
-    0 1 2 ... for <card num>).
+A CSV files may hold rows for multiple (hundreds or even thousands) of
+cards. ``pySim-prog`` is able to identify the rows either by ICCID
+(recommended as ICCIDs are normally not changed) or IMSI.
 
-  You also need to enter some parameters to select the device :
-   -t TYPE : type of card (supersim, magicsim, fakemagicsim or try 'auto')
-   -d DEV  : Serial port device (default /dev/ttyUSB0)
-   -b BAUD : Baudrate (default 9600)
+The CSV file format is a flexible format with mandatory and optional columns,
+here the same rules as for the commandline parameters apply. The column names
+match the command line options. The CSV file may also contain columns that are
+unknown to pySim-prog, such as inventory numbers, nicknames or parameters that
+are unrelated to the card programming process. ``pySim-prog`` will silently
+ignore all unknown columns.
+
+A CSV file may contain the following columns:
+
+* name
+* iccid (typically used as key)
+* mcc
+* mnc
+* imsi (may be used as key, but not recommended)
+* smsp
+* ki
+* opc
+* acc
+* pin_adm, adm1 or pin_adm_hex (must be present)
+* msisdn
+* epdgid
+* epdgSelection
+* pcscf
+* ims_hdomain
+* impi
+* impu
+* opmode
+* fplmn
+
+Due to historical reasons, and to maintain the compatibility between multiple different CSV file formats, the ADM pin
+may be stored in three different columns. Only one of the three columns must be available.
+
+* adm1: This column contains the ADM pin in numeric ASCII digit format. This format is the most common.
+* pin_adm: Same as adm1, only the column name is different
+* pin_adm_hex: If the ADM pin consists of raw HEX digits, rather then of numerical ASCII digits, then the ADM pin
+  can also be provided as HEX string using this column.
+

+
+The following commandline will instruct ``pySim-prog`` to use the provided CSV file as parameter source and the
+ICCID (read from the card before programming) as a key to identify the card. To use the IMSI as a key, the parameter
+``--read-imsi`` can be used instead of ``--read-iccid``. However, this option is only recommended to be used in very
+specific corner cases.
+
+``pySim-prog.py -p <pcsc_reader> --read-csv <path_to_csv_file> --source csv --read-iccid``
+
+It is also possible to pick a row from the CSV file by manually providing an ICCID (option ``--iccid``) or an IMSI
+(option ``--imsi``) that is then used as a key to find the matching row in the CSV file.
+
+``pySim-prog.py -p <pcsc_reader> --read-csv <path_to_csv_file> --source csv --iccid <iccid_value>``
+
+
+Writing CSV files
+~~~~~~~~~~~~~~~~~
+``pySim-prog`` is also able to generate CSV files that contain a subset of the parameters it has generated or received
+from some other source (commandline, CSV-File). The generated file will be header-less and contain the following
+columns:
+
+* name
+* iccid
+* mcc
+* mnc
+* imsi
+* smsp
+* ki
+* opc
+
+A commandline that makes use of the CSV write feature would look like this:
+
+``pySim-prog.py -p <pcsc_reader> --read-csv <path_to_input_csv_file> --read-iccid --source csv --write-csv <path_to_output_csv_file>``
+
+
+Batch programming
+~~~~~~~~~~~~~~~~~
+
+In case larger card batches need to be programmed, it is possible to use the ``--batch`` parameter to run ``pySim-prog`` in batch mode.
+
+The batch mode will prompt the user to insert a card. Once a card is detected in the reader, the programming is carried out. The user may then remove the card again and the process starts over. This allows for a quick and efficient card programming without permanent commandline interaction.

+Guide: Managing GP Keys
+=======================
+
+Most of todays smartcards follow the GlobalPlatform Card Specification and the included Security Domain model.
+UICCs and eUCCCs are no exception here.
+
+The Security Domain acts as an on-card representative of a card authority or administrator. It is used to perform tasks
+like the installation of applications or the provisioning and rotation of secure channel keys. It also acts as a secure
+key storage and offers all kinds of cryptographic services to applications that are installed under a specific
+Security Domain (see also GlobalPlatform Card Specification, section 7).
+
+In this tutorial, we will show how to work with the key material (keysets) stored inside a Security Domain and how to
+rotate (replace) existing keys. We will also show how to provision new keys.
+
+.. warning:: Making changes to keysets requires extreme caution as misconfigured keysets may lock you out permanently.
+	     It also strongly recommended to maintain at least one backup keyset that you can use as fallback in case
+	     the primary keyset becomes unusable for some reason.
+
+
+Selecting a Security Domain
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A typical smartcard, such as an UICC will have one primary Security Domain, called the Issuer Security Domain (ISD).
+When working with those cards, the ISD will show up in the UICC filesystem tree as `ADF.ISD` and can be selected like
+any other file.
+
+::
+   
+   pySIM-shell (00:MF)> select ADF.ISD
+   {
+      "application_id": "a000000003000000",
+      "proprietary_data": {
+         "maximum_length_of_data_field_in_command_message": 255
+      }
+   }
+
+When working with eUICCs, multiple Security Domains are involved. The model is slightly different from the classic
+model with one primary ISD. In the case of eUICCs, an ISD-R and an ISD-P exists.
+
+The ISD-R (Issuer Security Domain - Root) is indeed the primary ISD. Its purpose is to handle the installation of new
+profiles and to manage the already installed profiles. The ISD-R shows up as a `ADF.ISD-R` and can be selected normally
+(see above) The key material that allows access to the ISD-R is usually only known to the eUICC manufacturer.
+
+The ISD-P (Issuer Security Domain - Profile) is the primary ISD of the currently enabled profile. The ISD-P is
+comparable to the ISD we find on a UICC. The key material for the ISD-P should be known known to the ISP, which
+is the owner of the installed profile.
+
+Since the AID of the ISD-P is allocated during the profile installation and different for each profile, it is not known
+by pySim-shell. This means there will no `ADF.ISD-P` file show up in the file system, but we can simply select the
+ISD-R, request the AID of the ISD-P and switch over to that ISD-P using a raw APDU:
+``00a4040410`` + ``a0000005591010ffffffff8900001000`` + ``00``
+
+::

+    pySIM-shell (00:MF/ADF.ISD-R)>
+
+After that, the prompt will still show the ADF.ISD-R, but we are actually in ADF.ISD-P and the standard GlobalPlatform
+operations like `establish_scpXX`, `get_data`, and `put_key` should work. The same workaround can also be applied to any
+Supplementary Security Domain as well, provided that the AID is known to the user.
+
+
+Establishing a secure channel
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Before we can make changes to the keysets in the currently selected Security Domain we must first establish a secure channel
+with that Security Domain. The secure channel protocols commonly used for this are `SCP02` (see also GlobalPlatform Card
+Specification, section E.1.1) and `SCP03` (see also GlobalPlatform Card Specification – Amendment D). `SCP02` is slightly
+older and commonly used on UICCs. The more modern `SCP03` is commonly used on eUICCs. The main difference between the
+two is that `SCP02` uses 3DES while `SCP03` is based on AES.
+
+.. warning:: Secure channel protocols like `SCP02` and `SCP03` may manage an error counter to count failed login
+	     attempts. This means attempting to establish a secure channel with a wrong keyset multiple times may lock
+	     you out permanently. Double check the applied keyset before attempting to establish a secure channel.
+
+
+Example: `SCP02`
+----------------
+
+In the following example, we assume that we want to establish a secure channel with the ISD of a `sysmoUSIM-SJA5` UICC.
+Along with the card we have received the following keyset:
+

+Understanding Keysets
+~~~~~~~~~~~~~~~~~~~~~
+
+Before making any changes to keysets, it is recommended to check the status of the currently installed keysets. To do
+so, we use the `get_data` command to retrieve the `key_information`. We cannot read back the key values themselves, but
+we get a summary of the installed keys together with their KVN numbers, IDs, algorithm and key length values.
+
+Example: `key_information` from a `sysmoISIM-SJA5`:
+
+::
+
+    pySIM-shell (SCP02[03]:00:MF/ADF.ISD)> get_data key_information 
+    {
+        "key_information": [
+            {

+        ]
+    }
+
+The output from those two examples above may seem lengthy, but in order to move on and to provision own keys
+successfully, it is important to understand each aspect of it.
+
+Key Version Number (KVN)
+------------------------
+
+Each key is associated with a Key Version Number (KVN). Multiple keys that share the same KVN belong to the same
+keyset. In the first example above we can see that four keysets with KVN numbers 112, 1, 2 and 47 are provisioned.
+In the second example we see two keysets. One with KVN 50 and one with KVN 64.
+
+The term "Key Version Number" is misleading as this number is not really a version number. It's actually a unique
+identifier for a specific keyset that also defines with which Secure Channel Protocol a key can be used. This means
+that the KVN is not just an arbitrary number. The following (incomplete) table gives a hint which KVN numbers may be
+used with which Secure Channel Protocol.
+
++-----------+-------------------------------------------------------+
+| KVN range | Secure Channel Protocol                               |
++===========+=======================================================+
+| 1-15      | reserved for `SCP80` (OTA SMS)                        |

++-----------+-------------------------------------------------------+
+| 32-47     | reserved for `SCP02`                                  |
++-----------+-------------------------------------------------------+
+| 48-63     | reserved for `SCP03`                                  |
++-----------+-------------------------------------------------------+
+| 112       | Token key (RSA public or DES, also used with `SCP02`) |
++-----------+-------------------------------------------------------+
+| 113       | Receipt key (DES)                                     |
++-----------+-------------------------------------------------------+
+| 115       | DAP verifiation key (RS public or DES)                |
++-----------+-------------------------------------------------------+
+| 116       | reserved for CASD                                     |
++-----------+-------------------------------------------------------+
+| 117       | 16-byte DES key for Ciphered Load File Data Block     |
++-----------+-------------------------------------------------------+
+| 129-143   | reserved for `SCP81`                                  |
++-----------+-------------------------------------------------------+
+| 255       | reserved for ISD with SCP02 without SCP80 support     |
++-----------+-------------------------------------------------------+
+
+With that we can now understand that in the first example, the first and the last keyset is intended to be used with
+`SCP02` and that the second and the third keyset is intended to be used with `SCP80` (OTA SMS). In the second example we
+can see that the first keyset is intended to be used with `SCP03`, wheres the second should be usable with `SCP81`.
+
+
+Key Identifier
+--------------
+
+Each keyset consists of a number of keys, where each key has a different Key Identifier. The Key Identifier is usually
+an incrementing number that starts counting at 1. The Key Identifier is used to distinguish the keys within the keyset.
+The exact number of keys and their attributes depends on the secure channel protocol for which the keyset is intended
+for. Each secure channel protocol may have its specific requirements on how many keys of which which type, length or
+Key Identifier have to be present.
+
+However, almost all of the classic secure channel protocols (including  `SCP02`, `SCP03` and `SCP81`) make use of the
+following three-key scheme:
+
++----------------+---------+---------------------------------------+
+| Key Identifier | Keyname | Purpose                               |
++================+=========+=======================================+
+| 1              | ENC/KIC | encryption/decryption                 |
++----------------+---------+---------------------------------------+
+| 2              | MAC/KID | cryptographic checksumming/signing    |
++----------------+---------+---------------------------------------+
+| 3              | DEK/KIK | encryption/decryption of key material |
++----------------+---------+---------------------------------------+
+
+In this case, all three keys share the same length and are used with the same algorithm. The key length is often used
+to implicitly select sub-types of an algorithm. (e.g. a 16 byte key of type `aes` is associated with `AES128`, where a 32
+byte key would be associated with `AES256`).
+
+That different schemes are possible shows the second example. The `SCP80` keyset from the second example uses a scheme
+that works with two keys:
+
++----------------+---------+---------------------------------------+
+| Key Identifier | Keyname | Purpose                               |
++================+=========+=======================================+
+| 1              | TLS-PSK | pre-shared key used for TLS           |
++----------------+---------+---------------------------------------+
+| 2              | DEK/KIK | encryption/decryption of key material |
++----------------+---------+---------------------------------------+
+
+It should also be noted that the order in which keysets and keys appear is an implementation detail of the UICC/eUICC
+O/S. The order has no influence on how a keyset is interpreted. Only the Key Version Number (KVN) and the Key Identifier
+matter.
+	
+
+Rotating a keyset
+~~~~~~~~~~~~~~~~~
+
+Rotating keys is one of the most basic tasks one might want to perform on an UICC/eUICC before using it productively. In
+the following example we will illustrate how key rotation can be done. When rotating keys, only the key itself may
+change. For example it is not possible to change the key length or the algorithm used (see also GlobalPlatform Card
+Specification, section 11.8.2.3.3). Any key of the current Security Domain can be rotated, this also includes the key
+that was used to establish the secure channel.
+
+In the following example we assume that the Security Domain is selected and a secure channel is already established. We
+intend to rotate the keyset with KVN 112. Since this keyset uses triple DES keys with a key length of 16, we must
+replace it with a keyset with keys of the same nature.
+
+The new keyset shall look like this:
+
++----------------+---------+----------------------------------+
+| Key Identifier | Keyname | Keyvalue                         |
++================+=========+==================================+
+| 1              | ENC/KIC | 542C37A6043679F2F9F71116418B1CD5 |
++----------------+---------+----------------------------------+

+
+When passing the keys to the `put_key` commandline, we set the Key Identifier of the first key using the `--key-id`
+parameter. This Key Identifier will be valid for the first key (KIC) we pass. For all consecutive keys, the Key
+Identifier will be incremented automatically (see also GlobalPlatform Card Specification, section 11.8.2.2). To Ensure
+that the new KIC, KID and KIK keys get the correct Key Identifiers, it is crucial to maintain order when passing the
+keys in the `--key-data` arguments. It is also important that each `--key-data` argument is preceded by a `--key-type`
+argument that sets the algorithm correctly (`des` in this case).
+
+Finally we have to target the keyset we want to rotate by its KVN. The `--old-key-version-nr` argument is set to 112
+as this is identifies the keyset we want to rotate. The `--key-version-nr` is also set to 112 as we do not want to the
+KVN to be changed in this example. Changing the KVN while rotating a keyset is possible. In case the KVN has to change
+for some reason, the new KVN must be selected carefully to keep the key usable with the associated Secure Channel
+Protocol.
+
+The commandline that matches the keyset we had laid out above looks like this:
+::
+   
+   pySIM-shell (SCP02[03]:00:MF/ADF.ISD)> put_key --key-id 1 --key-type des --key-data 542C37A6043679F2F9F71116418B1CD5 --key-type des --key-data 34F11BAC8E5390B57F4E601372339E3C --key-type des --key-data 5524F4BECFE96FB63FC29D6BAAC6058B --old-key-version-nr 112 --key-version-nr 112
+
+After executing this put_key commandline, the keyset identified by KVN 122 is equipped with new keys. We can use
+`get_data key_information` to inspect the currently installed keysets. The output should appear unchanged as
+we only swapped out the keys. All other parameters, identifiers etc. should remain constant.
+
+.. warning:: It is technically possible to rotate a keyset in a `non atomic` way using one `put_key` commandline for
+	     each key. However, in case the targeted keyset is the one used to establish the current secure channel,
+	     this method should not be used since, depending on the UICC/eUICC model, half-written key material may
+	     interrupt the current secure channel.
+
+
+Removing a keyset
+~~~~~~~~~~~~~~~~~
+
+In some cases it is necessary to remove a keyset entirely. This can be done with the `delete_key` command. Here it is
+important to understand that `delete_key` only removes one specific key from a specific keyset. This means that you
+need to run a separate `delete_key` command for each key inside a keyset.
+
+In the following example we assume that the Security Domain is selected and a secure channel is already established. We
+intend to remove the keyset with KVN 112. This keyset consists of three keys.
+
+::
+
+   pySIM-shell (SCP02[03]:00:MF/ADF.ISD)> delete_key --key-ver 112 --key-id 1
+   pySIM-shell (SCP02[03]:00:MF/ADF.ISD)> delete_key --key-ver 112 --key-id 2
+   pySIM-shell (SCP02[03]:00:MF/ADF.ISD)> delete_key --key-ver 112 --key-id 3
+
+To verify that the keyset has been deleted properly, we can use the `get_data key_information` command to inspect the
+current status of the installed keysets. We should see that the key with KVN 112 is no longer present.
+
+
+Adding a keyset
+~~~~~~~~~~~~~~~
+
+In the following we will discuss how to add an entirely new keyset. The procedure is almost identical with the key
+rotation procedure we have already discussed and it is assumed that all details about the key rotation are understood.
+In this section we will go into more detail and and illustrate how to provision new 3DES, `AES128` and `AES256` keysets.
+
+It is important to keep in mind that storage space on smartcard is a precious resource. In many cases the amount of
+keysets that a Security Domain can store is limited. In some situations you may be forced to sacrifice one of your
+existing keysets in favor of a new keyset.
+
+The main difference between key rotation and the adding of new keys is that we do not simply replace an existing key.
+Instead an entirely new key is programmed into the Security Domain. Therefore the `put_key` commandline will have no
+`--old-key-version-nr` parameter. From the commandline perspective, this is already the only visible difference from a
+commandline that simply rotates a keyset. Since we are writing an entirely new keyset, we are free to chose the
+algorithm and the key length within the parameter range permitted by the targeted secure channel protocol. Otherwise
+the same rules apply.
+
+For reference, it should be mentioned that it is also possible to add or rotate keyset using multiple `put_key`
+commandlines. In this case one `put_key` commandline for each key is used. Each commandline will specify `--key-id` and
+`--key-version-nr` and one `--key-type` and `--key-data` tuple. However, when rotating or adding a keyset step-by-step,
+the whole process happens in a `non-atomic` way, which is less reliable. Therefore we will favor the `atomic method`
+
+In the following examples we assume that the Security Domain is selected and a secure channel is already established.
+
+
+Example: `3DES` key for `SCP02`
+-------------------------------
+
+Let's assume we want to provision a new 3DES keyset that we can use for SCP02. The keyset shall look like this:
+
++----------------+---------+----------------------------------+
+| Key Identifier | Keyname | Keyvalue                         |
++================+=========+==================================+
+| 1              | ENC/KIC | 542C37A6043679F2F9F71116418B1CD5 |

+| 3              | DEK/KIK | 5524F4BECFE96FB63FC29D6BAAC6058B |
++----------------+---------+----------------------------------+
+
+The keyset shall be a associated with the KVN 46. We have made sure before that KVN 46 is still unused and that this
+KVN number is actually suitable for SCP02 keys. As we are using 3DES, it is obvious that we have to pass 3 keys with 16
+byte length.
+
+To program the key, we may use the following commandline. As we can see, this commandline is almost the exact same as
+the one from the key rotation example where we were rotating a 3DES key. The only difference is that we didn't specify
+an old KVN number and that we have chosen a different KVN.
+
+::

+In case of success, the keyset should appear in the `key_information` among the other keysets that are already present.

+            },
+            ...
+        ]
+    }
+
+
+Example: `AES128` key for `SCP80`
+---------------------------------
+
+In this example we intend to provision a new `AES128` keyset that we can use with SCP80 (OTA SMS). The keyset shall look
+like this:
+
++----------------+---------+----------------------------------+
+| Key Identifier | Keyname | Keyvalue                         |
++================+=========+==================================+
+| 1              | ENC/KIC | 542C37A6043679F2F9F71116418B1CD5 |

+| 3              | DEK/KIK | 5524F4BECFE96FB63FC29D6BAAC6058B |
++----------------+---------+----------------------------------+
+
+In addition to that, we want to associate this key with KVN 3. We have inspected the currently installed keysets before
+and made sure that KVN 3 is still unused. We are also aware that for SCP80 we may only use KVN values from 1 to 15.
+
+For `AES128`, we specify the algorithm using the `--key-type aes` parameter. The selection between `AES128` and `AES256` is
+done implicitly using the key length. Since we want to use `AES128` in this case, all three keys have a length of 16 byte.

+
+
+Example: `AES256` key for `SCP03`
+---------------------------------
+
+Let's assume we want to provision a new `AES256` keyset that we can use for SCP03. The keyset shall look like this:
+
++----------------+---------+------------------------------------------------------------------+
+| Key Identifier | Keyname | Keyvalue                                                         |

++----------------+---------+------------------------------------------------------------------+
+
+In addition to that, we assume that we want to associate this key with KVN 51. This KVN number falls in the range of
+48 - 63 and is therefore suitable for a key that shall be usable with SCP03. We also made sure before that KVN 51 is
+still unused.
+
+With that we can go ahead and make up the following commandline:
+::
+   
+   pySIM-shell (SCP02[03]:00:MF/ADF.ISD)> put_key --key-id 1 --key-type aes --key-data 542C37A6043679F2F9F71116418B1CD5542C37A6043679F2F9F71116418B1CD5 --key-type aes --key-data 34F11BAC8E5390B57F4E601372339E3C34F11BAC8E5390B57F4E601372339E3C --key-type aes --key-data 5524F4BECFE96FB63FC29D6BAAC6058B5524F4BECFE96FB63FC29D6BAAC6058B --key-version-nr 51

+            },
+            ...
+        ]
+    }
+
+
+Example: `AES128` key for `SCP81`
+---------------------------------
+
+In this example we will show how to provision a new `AES128` keyset for `SCP81`. We will provision this keyset under
+KVN 64. The keyset we intend to apply shall look like this:
+
++----------------+---------+----------------------------------+
+| Key Identifier | Keyname | Keyvalue                         |
++================+=========+==================================+

++----------------+---------+----------------------------------+
+
+With that we can put together the following command line:
+
+::
+
+    put_key --key-id 1 --key-type tls_psk --key-data 000102030405060708090a0b0c0d0e0f --key-type aes --key-data 000102030405060708090a0b0c0d0e0f --key-version-nr 64

+Remote access to an UICC/eUICC
+==============================
+
+To access a card with pySim-shell, it is not strictly necessary to have physical
+access to it. There are solutions that allow remote access to UICC/eUICC cards.
+In this section we will give a brief overview.
+
+
+osmo-remsim
+-----------
+
+osmo-remsim is a suite of software programs enabling physical/geographic
+separation of a cellular phone (or modem) on the one hand side and the
+UICC/eUICC card on the other side.
+
+Using osmo-remsim, you can operate an entire fleet of modems/phones, as well as
+banks of SIM cards and dynamically establish or remove the connections between
+modems/phones and cards.
+
+To access remote cards with pySim-shell via osmo-remseim (RSPRO), the
+provided libifd_remsim_client would be used to provide a virtual PC/SC reader
+on the local machine. pySim-shell can then access this reader like any other
+PC/SC reader.
+
+More information on osmo-remsim can be found under:
+ * https://osmocom.org/projects/osmo-remsim/wiki
+ * https://ftp.osmocom.org/docs/osmo-remsim/master/osmo-remsim-usermanual.pdf
+
+
+Android APDU proxy
+------------------
+
+Android APDU proxy is an Android app that provides a bridge between a host
+computer and the UICC/eUICC slot of an Android smartphone.
+
+The APDU proxy connects to VPCD server that runs on the remote host (in this
+case the local machine where pySim-shell is running). The VPCD server then
+provides a virtual PC/SC reader, that pySim-shell can access like any other
+PC/SC reader.
+
+On the Android side the UICC/eUICC is accessed via OMAPI (Open Mobile API),
+which is available in Android since API level Android 8 (API level 29).
+

+saip-tool
+=========
+
+eSIM profiles are stored as a sequence of profile element (PE) objects in an ASN.1 DER encoded binary file. To inspect,
+verify or make changes to those files, the `saip-tool.py` utility can be used.
+
+NOTE: The file format, eSIM SAIP (SimAlliance Interoperable Profile) is specified in `TCA eUICC Profile Package:
+Interoperable Format Technical Specification`
+
+
+Profile Package Examples
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+pySim ships with a set of TS48 profile package examples. Those examples can be found in `pysim/smdpp-data/upp`. The
+files can be used as input for `saip-tool.py`. (see also GSMA TS.48 - Generic eUICC Test Profile for Device Testing)
+
+See also: https://github.com/GSMATerminals/Generic-eUICC-Test-Profile-for-Device-Testing-Public
+
+JAVA card applets
+~~~~~~~~~~~~~~~~~
+
+The `saip-tool.py` can also be used to manage JAVA-card applets (Application PE) inside a profile package. The user has
+the option to add, remove and inspect applications and their instances. In the following we will discuss a few JAVA-card
+related use-cases of `saip-tool.py`
+
+NOTE: see also `contrib` folder for script examples (`saip-tool_example_*.sh`)
+
+Inserting applications
+----------------------
+
+An application is usually inserted in two steps. In the first step, the application PE is created and populated with
+the executable code from a provided `.cap` or `.ijc` file. The user also has to pick a suitable load block AID.
+
+The application instance, which exists inside the application PE, is created in a second step. Here the user must
+reference the load block AID and pick, among other application related parameters, a suitable class and instance AID.
+
+Example: Adding a JAVA-card applet to an existing profile package
+::
+
+  # Step #1: Create the application PE and load the ijc contents from the .cap file:
+  $ ./contrib/saip-tool.py upp.der add-app --output-file upp_with_app.der --applet-file app.cap --aid '1122334455'
+  Read 28 PEs from file 'upp.der'
+  Applying applet file: 'app.cap'...
+  application PE inserted into PE Sequence after securityDomain PE AID: a000000151000000
+  Writing 29 PEs to file 'upp_with_app.der'...
+
+  # Step #2: Create the application instance inside the application PE created in step #1:
+  $ ./contrib/saip-tool.py upp_with_app.der add-app-inst --output-file upp_with_app_and_instance.der \
+          --aid '1122334455' \
+          --class-aid '112233445501' \
+          --inst-aid '112233445501' \
+          --app-privileges '00' \
+          --app-spec-pars '00' \
+          --uicc-toolkit-app-spec-pars '01001505000000000000000000000000'
+  Read 29 PEs from file 'upp_with_app.der'
+  Found Load Package AID: 1122334455, adding new instance AID: 112233445501 to Application PE...
+  Writing 29 PEs to file 'upp_with_app_and_instance.der'...
+
+NOTE: The parameters of the sub-commands `add-app` and `add-app-inst` are application specific. It is up to the application
+developer to pick parameters that suit the application correctly. For an exact command reference see section
+`saip-tool syntax`. For parameter details see `TCA eUICC Profile Package: Interoperable Format Technical Specification`,
+section 8.7 and ETSI TS 102 226, section 8.2.1.3.2
+
+
+Inspecting applications
+-----------------------
+
+To inspect the application PE contents of an existing profile package, sub-command `info` with parameter '--apps' can
+be used. This command lists out all application and their parameters in detail. This allows an application developer
+to check if the applet insertaion was carried out as expected.
+
+Example: Listing applications and their parameters
+::
+
+  $ ./contrib/saip-tool.py upp_with_app_and_instance.der info --apps
+  Read 29 PEs from file 'upp_with_app_and_instance.der'
+  Application #0:
+          loadBlock:
+                  loadPackageAID: '1122334455' (5 bytes)
+                  loadBlockObject: '01000fdecaffed010204000105d07002ca440200...681080056810a00633b44104b431066800a10231' (569 bytes)
+          instanceList[0]:
+                  applicationLoadPackageAID: '1122334455' (5 bytes)
+                  classAID: '112233445501' (8 bytes)
+                  instanceAID: '112233445501' (8 bytes)
+                  applicationPrivileges: '00' (1 bytes)
+                  lifeCycleState: '07' (1 bytes)
+                  applicationSpecificParametersC9: '00' (1 bytes)
+                  applicationParameters:
+                          uiccToolkitApplicationSpecificParametersField: '01001505000000000000000000000000' (16 bytes)
+
+In case further analysis with external tools or transfer of applications from one profile package to another is
+necessary, the executable code in the `loadBlockObject` field can be extracted to an `.ijc` or an `.cap` file.
+
+Example: Extracting applications from a profile package
+::
+
+  $ ./contrib/saip-tool.py upp_with_app_and_instance.der extract-apps --output-dir ./apps --format ijc
+  Read 29 PEs from file 'upp_with_app_and_instance.der'
+  Writing Load Package AID: 1122334455 to file ./apps/8949449999999990023f-1122334455.ijc
+
+
+Removing applications
+---------------------
+
+An application PE can be removed using sub-command `remove-app`. The user passes the load package AID as parameter. Then
+`saip-tool.py` will search for the related application PE and delete it from the PE sequence.
+
+Example: Remove an application from a profile package
+::
+
+  $ ./contrib/saip-tool.py upp_with_app_and_instance.der remove-app --output-file upp_without_app.der --aid '1122334455'
+  Read 29 PEs from file 'upp_with_app_and_instance.der'
+  Found Load Package AID: 1122334455, removing related PE (id=23) from Sequence...
+  Removing PE application (id=23) from Sequence...
+  Writing 28 PEs to file 'upp_without_app.der'...
+
+In some cases it is useful to remove only an instance from an existing application PE. This may be the case when the
+an application developer wants to modify parameters of an application by removing and re-adding the instance. The
+operation basically rolls the state back to step 1 explained in section :ref:`Inserting applications`
+
+Example: Remove an application instance from an application PE
+::
+
+  $ ./contrib/saip-tool.py upp_with_app_and_instance.der remove-app-inst --output-file upp_without_app.der --aid '1122334455' --inst-aid '112233445501'
+  Read 29 PEs from file 'upp_with_app_and_instance.der'
+  Found Load Package AID: 1122334455, removing instance AID: 112233445501 from Application PE...
+  Removing instance from Application PE...
+  Writing 29 PEs to file 'upp_with_app.der'...

+sim-rest-server
+===============
+
+Sometimes there are use cases where a [remote] application will need
+access to a USIM for authentication purposes.  This is, for example, in
+case an IMS test client needs to perform USIM based authentication
+against an IMS core.
+
+The pysim repository contains two programs: `sim-rest-server.py` and
+`sim-rest-client.py` that implement a simple approach to achieve the
+above:
+
+`sim-rest-server.py` speaks to a [usually local] USIM via the PC/SC
+API and provides a high-level REST API towards [local or remote]
+applications that wish to perform UMTS AKA using the USIM.
+
+`sim-rest-client.py` implements a small example client program to
+illustrate how the REST API provided by `sim-rest-server.py` can be
+used.
+
+REST API Calls
+--------------
+
+POST /sim-auth-api/v1/slot/SLOT_NR
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+where SLOT_NR is the integer-encoded slot number (corresponds to PC/SC
+reader number).  When using a single sysmoOCTSIM board, this is in the range of 0..7
+
+Example: `/sim-auth-api/v1/slot/0` for the first slot.
+
+Request Body
+############
+
+The request body is a JSON document, comprising of
+    1. the RAND and AUTN parameters as hex-encoded string
+    2. the application against which to authenticate (USIM, ISIM)
+
+Example:
+::
+
+        {
+            "rand": "bb685a4b2fc4d697b9d6a129dd09a091",
+            "autn": "eea7906f8210000004faf4a7df279b56"
+        }
+
+HTTP Status Codes
+#################
+
+HTTP status codes are used to represent errors within the REST server
+and the SIM reader hardware.  They are not used to communicate protocol
+level errors reported by the SIM Card.  An unsuccessful authentication
+will hence have a `200 OK` HTTP Status code and then encode the SIM
+specific error information in the Response Body.

+smpp-ota-tool
+=============
+
+The `smpp-ota-tool` allows users to send OTA SMS messages containing APDU scripts (RFM, RAM) via an SMPP server. The
+intended audience are developers who want to test/evaluate the OTA SMS interface of a SIM/UICC/eUICC. `smpp-ota-tool`
+is intended to be used as a companion tool for :ref:`pySim-smpp2sim`, however it should be usable on any other SMPP
+server (such as a production SMSC of a live cellular network) as well.
+
+From the technical perspective `smpp-ota-tool` takes the role of an SMPP ESME. It takes care of the encoding, encryption
+and checksumming (signing) of the RFM/RAM OTA SMS and eventually submits it to the SMPP server. The program then waits
+for a response. The response is automatically parsed and printed on stdout. This makes the program also suitable to be
+called from shell scripts.
+
+.. note:: In the following we will we will refer to `SIM` as one of the following: `SIM`, `USIM`, `ISIM`, `UICC`,
+	  `eUICC`, `eSIM`.
+
+Applying OTA keys
+~~~~~~~~~~~~~~~~~
+
+Depending on the `SIM` type you will receive one or more sets of keys which you can use to communicate with the `SIM`
+through a secure channel protocol. When using the OTA SMS method, the SCP80 protocol is used and it therefore crucial
+to use a keyset that is actually suitable for SCP80.
+
+A keyset usually consists of three keys:
+
+#. KIC: the key used for ciphering (encryption/decryption)
+#. KID: the key used to compute a cryptographic checksum (signing)
+#. KIK: the key used to encrypt/decrypt key material (key rotation, adding of new keys)
+
+From the transport security perspective, only KIC and KID are relevant. The KIK (also referenced as "Data Encryption
+Key", DEK) is only used when keys are rotated or new keys are added (see also ETSI TS 102 226, section 8.2.1.5).
+
+When the keyset is programmed into the security domain of the `SIM`, it is tied to a specific cryptographic algorithm
+(3DES, AES128 or AES256) and a so called Key Version Number (KVN). The term "Key Version Number" is misleading, since
+it is actually not a version number. It is a unique identifier of a certain keyset which also identifies for which
+secure channel protocol the keyset may be used. Keysets with a KVN from 1-15 (``0x01``-``0x0F``) are suitable for SCP80.
+This means that it is not only important to know just the KIC/KID/KIK keys. Also the related algorithms and the KVN
+numbers must be known.
+
+.. note:: SCP80 keysets typically start counting from 1 upwards. Typical configurations use a set of 3 keysets with
+	  KVN numbers 1-3.
+
+Addressing an Application
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When communicating with a specific application on a `SIM` via SCP80, it is important to address that application with
+the correct parameters. The following two parameters must be known in advance:
+
+#. TAR: The Toolkit Application Reference (TAR) number is a three byte value that uniquely addresses an application
+   on the `SIM`. The exact values may vary (see also ETSI TS 101 220, Table D.1).
+#. MSL: The Minimum Security Level (MSL) is a bit-field that dictates which of the security measures encoded in the
+   SPI are mandatory (see also ETSI TS 102 225, section 5.1.1).
+
+A practical example
+~~~~~~~~~~~~~~~~~~~
+
+.. note:: This tutorial assumes that pySim-smpp2sim is running on the local machine with its default parameters.
+	  See also :ref:`pySim-smpp2sim`.
+
+Let's assume that an OTA SMS shall be sent to the SIM RFM application of an sysmoISIM-SJA2. What we want to do is to
+select DF.GSM and to get the select response back.
+
+We have received the following key material from the `SIM` vendor:
+
+::
+
+   KIC1: F09C43EE1A0391665CC9F05AF4E0BD10
+   KID1: 01981F4A20999F62AF99988007BAF6CA
+   KIK1: 8F8AEE5CDCC5D361368BC45673D99195
+   KIC2: 01022916E945B656FDE03F806A105FA2
+   KID2: D326CB69F160333CC5BD1495D448EFD6
+   KIK2: 08037E0590DFE049D4975FFB8652F625
+   KIC3: 2B22824D0D27A3A1CEEC512B312082B4
+   KID3: F1697766925A11F4458295590137B672
+   KIK3: C7EE69B2C5A1C8E160DD36A38EB517B3
+
+Those are three keysets. The enumeration is directly equal to the KVN used. All three keysets are 3DES keys, which
+means triple_des_cbc2 is the correct algorithm to use.
+
+.. note:: The key set configuration can be confirmed by retrieving the key configuration using
+	  `get_data key_information` from within an SCP02 session on ADF.ISD.
+
+In this example we intend to address the SIM RFM application on the `SIM`. Which according to the manual has TAR ``B00010``
+and MSL ``0x06``. When we hold ``0x06`` = ``0b00000110`` against the SPI coding chart (see also ETSI TS 102 225,
+section 5.1.1). We can deduct that Ciphering and Cryptographic Checksum are mandatory.
+
+.. note:: The MSL (see also ETSI TS 102 226, section 6.1) is assigned to an application by the `SIM` issuer. It is a
+	  custom decision and may vary with different `SIM` types/profiles. In the case of sysmoISIM-SJS1/SJA2/SJA5 the
+	  counter requirement has been waived to simplify lab/research type use. In productive environments, `SIM`
+	  applications should ideally use an MSL that makes the counter mandatory.
+
+In order to select DF.GSM (``0x7F20``) and to retrieve the select response, two APDUs are needed. The first APDU is the
+select command ``A0A40000027F20`` and the second is the related get-response command ``A0C0000016``. Those APDUs will be
+concatenated and are sent in a single message. The message containing the concatenated APDUs works as a script that
+is received by the SIM RFM application and then executed. This method poses some limitations that have to be taken into
+account when making requests like this (see also ETSI TS 102 226, section 5).
+
+With this information we may now construct a commandline for `smpp-ota-tool.py`. We will pass the KVN as kid_idx and
+kic_idx (see also ETSI TS 102 225, Table 2, fields `KIc` and `KID`). Both index values should refer to the same
+keyset/KVN as keysets should not be mixed. (`smpp-ota-tool` still provides separate parameters anyway to allow testing
+with invalid keyset combinations)

+The result we see is the select response of DF.GSM and a status word indicating that the last command has been
+processed normally.
+
+As we can see, this mechanism now allows us to perform small administrative tasks remotely. We can read the contents of
+files remotely or make changes to files. Depending on the changes we make, there may be security issues arising from
+replay attacks. With the commandline above, the communication is encrypted and protected by a cryptographic checksum,
+so an adversary can neither read, nor alter the message. However, an adversary could still replay an intercepted
+message and the `SIM` would happily execute the contained APDUs again.
+
+To prevent this, we may include a replay protection counter within the message. In this case, the MSL indicates that a
+replay protection counter is not required. However, to extended the security of our messages, we may chose to use a
+counter anyway. In the following example, we will encode a counter value of 100. We will instruct the `SIM` to make sure
+that the value we send is higher than the counter value that is currently stored in the `SIM`.
+
+To add a replay connection counter we add the commandline arguments `--cntr-req` to set the counter requirement and
+`--cntr` to pass the counter value.

+==============
+
+This is a program to emulate the entire communication path SMSC-CN-RAN-ME
+that is usually between an OTA backend and the SIM card.  This allows
+to play with SIM OTA technology without using a mobile network or even
+a mobile phone.
+
+An external application can act as SMPP ESME and must encode (and
+encrypt/sign) the OTA SMS and submit them via SMPP to this program, just
+like it would submit it normally to a SMSC (SMS Service Centre).  The
+program then re-formats the SMPP-SUBMIT into a SMS DELIVER TPDU and
+passes it via an ENVELOPE APDU to the SIM card that is locally inserted
+into a smart card reader.
+
+The path from SIM to external OTA application works the opposite way.
+
+The default SMPP system_id is `test`.  Likewise, the default SMPP
+password is `test`
+
+Running pySim-smpp2sim
+----------------------
+
+The command accepts the same command line arguments for smart card interface device selection as pySim-shell,
+as well as a few SMPP specific arguments:

+
+Example execution with sample output
+------------------------------------
+
+So for a simple system with a single PC/SC device, you would typically use something like
+`./pySim-smpp2sim.py -p0` to start the program.  You will see output like this at start-up
+::
+
+  Using reader PCSC[HID Global OMNIKEY 3x21 Smart Card Reader [OMNIKEY 3x21 Smart Card Reader] 00 00]
+  INFO     root: Binding Virtual SMSC to TCP Port 2775 at ::
+
+The application has hence bound to local TCP port 2775 and expects your SMS-sending applications to send their
+SMS there.  Once you do, you will see log output like below:
+::
+

+============
+
+Subscriber concealment is an important feature of the 5G SA architecture: It avoids the many privacy
+issues associated with having a permanent identifier (SUPI, traditionally the IMSI) transmitted in plain text
+over the air interface.  Using SUCI solves this issue not just for the air interface; it even ensures the SUPI/IMSI
+is not known to the visited network (VPLMN) at all.
+
+In principle, the SUCI mechanism works by encrypting the SUPI by asymmetric (public key) cryptography:
+Only the HPLMN is in possession of the private key and hence can decrypt the SUCI to the SUPI, while
+each subscriber has the public key in order to encrypt their SUPI into the SUCI.  In reality, the
+details are more complex, as there are ephemeral keys and cryptographic MAC involved.
+
+In any case, in order to operate a SUCI-enabled 5G SA network, you will have to
+
+#. generate a ECC key pair of public + private key
+#. deploy the public key on your USIMs
+#. deploy the private key on your 5GC, specifically the UDM function
+
+pysim contains (in its `contrib` directory) a small utility program that can make it easy to generate
+such keys: `suci-keytool.py`
+
+Generating keys
+~~~~~~~~~~~~~~~
+
+Example: Generating a *secp256r1* ECC public key pair and storing it to `/tmp/suci.key`:
+::
+
+        $ ./contrib/suci-keytool.py --key-file /tmp/suci.key generate-key --curve secp256r1
+
+Dumping public keys
+~~~~~~~~~~~~~~~~~~~
+
+In order to store the key to SIM cards as part of `ADF.USIM/DF.5GS/EF.SUCI_Calc_Info`, you will need
+a hexadecimal representation of the public key.  You can achieve that using the `dump-pub-key` operation
+of suci-keytool:
+
+Example: Dumping the public key part from a previously generated key file:
+::
+
+        $ ./contrib/suci-keytool.py --key-file /tmp/suci.key dump-pub-key
+        0473152f32523725f5175d255da2bd909de97b1d06449a9277bc629fe42112f8643e6b69aa6dce6c86714ccbe6f2e0f4f4898d102e2b3f0c18ce26626f052539bb
+
+If you want the point-compressed representation, you can use the `--compressed` option:
+::
+
+        $ ./contrib/suci-keytool.py --key-file /tmp/suci.key dump-pub-key --compressed
+        0373152f32523725f5175d255da2bd909de97b1d06449a9277bc629fe42112f864

 Guide: Enabling 5G SUCI
-========================
+=======================
 
 SUPI/SUCI Concealment is a feature of 5G-Standalone (SA) to encrypt the
 IMSI/SUPI with a network operator public key.  3GPP Specifies two different
 variants for this:
 
-* SUCI calculation *in the UE*, using data from the SIM
+* SUCI calculation *in the UE*, using key data from the SIM
 * SUCI calculation *on the card itself*
 
-pySIM supports writing the 5G-specific files for *SUCI calculation in the UE* on USIM cards, assuming that
-your cards contain the required files, and you have the privileges/credentials to write to them.  This is
-the case using sysmocom sysmoISIM-SJA2 cards (or successor products).
+pySim supports writing the 5G-specific files for *SUCI calculation in the UE* on USIM cards, assuming
+that your cards contain the required files, and you have the privileges/credentials to write to them.
+This is the case using sysmocom sysmoISIM-SJA2 or any flavor of sysmoISIM-SJA5.
 
-In short, you can enable SUCI with these steps:
+There is no 3GPP/ETSI standard method for configuring *SUCI calculation on the card*; pySim currently
+supports the vendor-specific method for the sysmoISIM-SJA5-S17).
 
-* activate USIM **Service 124**
-* make sure USIM **Service 125** is disabled
-* store the public keys in **SUCI_Calc_Info**
-* set the **Routing Indicator** (required)
+This document describes both methods.
 
-If you want to disable the feature, you can just disable USIM Service 124 (and 125).

+SUCI calculation by the USIM
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The SUCI calculation can also be performed by the USIM application on the UICC
+directly. The UE then uses the GET IDENTITY command (see also 3GPP TS 31.102,
+section 7.5) to retrieve a SUCI value.
+
+The sysmoISIM-SJA5-S17 supports *SUCI calculation by the USIM*. The configuration
+is not much different to the above described configuration of *SUCI calculation
+in the UE*.
+
+The main difference is how the key provisioning is done. When the SUCI
+calculation is done by the USIM, then the key material is not accessed by the
+UE. The specification (see also 3GPP TS 31.102, section 7.5.1.1), also does not
+specify any file or file format to store the key material. This means the exact
+way to perform the key provisioning is an implementation detail of the USIM
+card application.
+
+In the case of sysmoISIM-SJA5-S17, the key material for *SUCI calculation by the USIM* is stored in
+`ADF.USIM/DF.SAIP/EF.SUCI_Calc_Info` (**not** in `ADF.USIM/DF.5GS/EF.SUCI_Calc_Info`!).

+   pySIM-shell (00:MF/ADF.USIM/DF.SAIP)> select EF.SUCI_Calc_Info
+
+The file format is exactly the same as specified in 3GPP TS 31.102, section
+4.4.11.8. This means the above described key provisioning procedure can be
+applied without any changes, except that the file location is different.
+
+To signal to the UE that the USIM is setup up for SUCI calculation, service
+125 must be enabled in addition to service 124 (see also 3GPP TS 31.102,

+# An external application must encode (and encrypt/sign) the OTA SMS
+# and submit them via SMPP to this program, just like it would submit
+# it normally to a SMSC (SMS Service Centre).  The program then re-formats

+# APDU to the SIM card that is locally inserted into a smart card reader.
+#
+# The path from SIM to external OTA application works the opposite way.

-    @abc.abstractmethod
-    def apply(self, pe_seq: ProfileElementSequence):
+    This class is abstract, you will only use subclasses in practice.
+
+    Subclasses have to implement the apply_val() classmethods, and may choose to override the default validate_val()
+    implementation.
+    The default validate_val() is a generic validator that uses the following class members (defined in subclasses) to
+    configure the validation; if any of them is None, it means that the particular validation is skipped:
+
+    allow_types: a list of types permitted as argument to validate_val(); allow_types = (bytes, str,)
+    allow_chars: if val is a str, accept only these characters; allow_chars = "0123456789"
+    strip_chars: if val is a str, remove these characters; strip_chars = ' \t\r\n'
+    min_len: minimum length of an input str; min_len = 4
+    max_len: maximum length of an input str; max_len = 8
+    allow_len: permit only specific lengths; allow_len = (8, 16, 32)
+
+    Subclasses may change the meaning of these by overriding validate_val(), for example that the length counts
+    resulting bytes instead of a hexstring length. Most subclasses will be covered by the default validate_val().
+
+    Usage examples, by example of Iccid:
+
+    1) use a ConfigurableParameter instance, with .input_value and .value state::
+
+          iccid = Iccid()
+          try:
+            iccid.input_value = '123456789012345678'
+            iccid.validate()
+          except ValueError:
+            print(f"failed to validate {iccid.name} == {iccid.input_value}")
+
+          pes = ProfileElementSequence.from_der(der_data_from_file)
+          try:
+            iccid.apply(pes)

+            print(f"failed to apply {iccid.name} := {iccid.input_value}")
+
+          changed_der = pes.to_der()
+
+    2) use a ConfigurableParameter class, without state::
+
+          cls = Iccid
+          input_val = '123456789012345678'
