sysmocom_sjs1: CardModel for the sysmoUSIM-SJS1

SJS1 model lifted off the the legacy
SysmoUSIMSJS1.program(), ADM is ADM1 with CHV 0x0a,
already used by the generic UiccCardBase default.

+# The card (specifically a SD supporting SCP81) is the TLS client:
+# - it opens a TCP connection to this server,
+# - performs a TLS handshake authenticated with a PSK,
+# - and then drives the HTTP admin loop of to fetch remote APDU command strings
+# - and posts back their responses.
+# This program is the server side of that exchange, it:
+# - accepts the PSK-TLS connection,
+# - hands the card a queue of commands

+Guide: Managing GP Keys
+=======================
+
+Most of today's 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's 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 fundamentally different from the classic
+model with one primary Security Domain (ISD). In the case of eUICCs, an ISD-R (Issuer Security Domain - Root) and an
+ISD-P (Issuer Security Domain - Profile) exist (see also: GSMA SGP.02, section 2.2.1).
+
+The ISD-P is established by the ISD-R during the profile installation and serves as a secure container for an eSIM
+profile. Within the ISD-P the eSIM profile establishes a dedicated Security Domain called `MNO-SD` (see also GSMA
+SGP.02, section 2.2.4). This `MNO-SD` is comparable to the Issuer Security Domain (ISD) we find on UICCs. The AID of
+`MNO-SD` is either the default AID for the Issuer Security Domain (see also GlobalPlatform, section H.1.3) or a
+different value specified by the provider of the eSIM profile.
+
+Since the AID of the `MNO-SD` is not a fixed value, it is not known by `pySim-shell`. This means there will be no
+`ADF.ISD` file shown in the file system, but we can simply select the `ADF.ISD-R` first and then select the `MNO-SD`
+using a raw APDU. In the following example we assume that the default AID (``a000000151000000``) is used  The APDU
+would look like this: ``00a4040408`` + ``a000000151000000`` + ``00``
+
+::
+
+   pySIM-shell (00:MF)> select ADF.ISD-R
+   {
+       "application_id": "a0000005591010ffffffff8900000100",
+       "proprietary_data": {
+           "maximum_length_of_data_field_in_command_message": 255
+       },
+       "isdr_proprietary_application_template": {
+           "supported_version_number": "020300"
+       }
+   }
+   pySIM-shell (00:MF/ADF.ISD-R)> apdu 00a4040408a00000015100000000
+   SW: 9000, RESP: 6f108408a000000151000000a5049f6501ff
+
+After that, the prompt will still show the `ADF.ISD-R`, but we are actually in `ADF.ISD` and the standard GlobalPlatform
+operations like `establish_scpXX`, `get_data`, and `put_key` should work. By doing this, we simply have tricked
+`pySim-shell` into making the GlobalPlatform related commands available for some other Security Domain we are not
+interested in. With the raw APDU we then have swapped out the Security Domain under the hood. The same workaround can
+be applied to any Security Domain, 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. In the following examples we will use `SCP02` (see also GlobalPlatform Card
+Specification, section E.1.1) and `SCP03` (see also GlobalPlatform Card Specification – Amendment D) to establish the
+secure channel. `SCP02` is slightly older than `SCP03`. 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.
+
+.. warning:: The key values used in the following examples are random key values used for illustration purposes only.
+	     Each UICC or eSIM profile is shipped with individual keys, which means that the keys used below will not
+	     work with your UICC or eSIM profile. You must replace the key values with the values you have received
+	     from your UICC vendor or eSIM profile provider.
+
+
+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:
+
++---------+----------------------------------+
+| Keyname | Keyvalue                         |
++=========+==================================+
+| ENC/KIC | F09C43EE1A0391665CC9F05AF4E0BD10 |

+| MAC/KID | 01981F4A20999F62AF99988007BAF6CA |
++---------+----------------------------------+
+| DEK/KIK | 8F8AEE5CDCC5D361368BC45673D99195 |
++---------+----------------------------------+
+
+This keyset is tied to the key version number KVN 122 and is configured as a DES keyset. We can use this keyset to
+establish a secure channel using the SCP02 Secure Channel Protocol.
+
+::
+
+    pySIM-shell (00:MF/ADF.ISD)> establish_scp02 --key-enc F09C43EE1A0391665CC9F05AF4E0BD10 --key-mac 01981F4A20999F62AF99988007BAF6CA --key-dek 8F8AEE5CDCC5D361368BC45673D99195  --key-ver 112 --security-level 3
+    Successfully established a SCP02[03] secure channel
+
+
+Example: `SCP03`
+----------------
+
+The establishment of a secure channel via SCP03 works just the same. In the following example we will establish a
+secure channel to the `MNO-SD` of an eSIM profile. The SCP03 keyset we use is tied to KVN 48 and looks like this:
+
++---------+------------------------------------------------------------------+
+| Keyname | Keyvalue                                                         |
++=========+==================================================================+
+| ENC/KIC | 63af517c29ad6ac6fcadfe6ac8a3c8a041d8141c7eb845ef1cba6112a325e430 |
++---------+------------------------------------------------------------------+

++---------+------------------------------------------------------------------+
+
+We assume that the `MNO-SD` is already selected (see above). We may now establish the SCP03 secure channel:
+
+::
+
+   pySIM-shell (00:MF/ADF.ISD-R)> establish_scp03 --key-enc 63af517c29ad6ac6fcadfe6ac8a3c8a041d8141c7eb845ef1cba6112a325e430 --key-mac 54b9ad6713ae922f54014ed762132e7b59bdcd2a2a6beba98fb9afe6b4df27e1 --key-dek cbb933ba2389da93c86c112739cd96389139f16c6f80f7d16bf3593e407ca893 --key-ver 48 --security-level 3
+   Successfully established a SCP03[03] secure channel
+
+
+
+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`. This command does not require the establishment of
+a secure channel. We also 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": [
+            {
+                "key_information_data": {

+        ]
+    }
+
+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)                        |
++-----------+-------------------------------------------------------+
+| 17        | reserved for DAP specified in ETSI TS 102 226         |
++-----------+-------------------------------------------------------+
+| 32-47     | reserved for `SCP02`                                  |
++-----------+-------------------------------------------------------+
+| 48-63     | reserved for `SCP03`                                  |
++-----------+-------------------------------------------------------+
+| 64-79     | reserved for `SCP81` (GSMA SGP.02, section 2.2.5.1)   |
++-----------+-------------------------------------------------------+
+| 112       | Token key (RSA public or DES, also used with `SCP02`) |
++-----------+-------------------------------------------------------+
+| 113       | Receipt key (DES)                                     |
++-----------+-------------------------------------------------------+
+| 115       | DAP verification key (RS public or DES)               |
++-----------+-------------------------------------------------------+
+| 116       | reserved for CASD                                     |
++-----------+-------------------------------------------------------+
+| 117       | 16-byte DES key for Ciphered Load File Data Block     |
++-----------+-------------------------------------------------------+
+| 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`).
+
+The second example shows that different schemes are possible. 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 |
++----------------+---------+----------------------------------+
+| 2              | MAC/KID | 34F11BAC8E5390B57F4E601372339E3C |
++----------------+---------+----------------------------------+
+| 3              | DEK/KIK | 5524F4BECFE96FB63FC29D6BAAC6058B |
++----------------+---------+----------------------------------+
+
+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 identifies the keyset we want to rotate. The `--key-version-nr` is also set to 112 as we do not want
+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 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 |
++----------------+---------+----------------------------------+
+| 2              | MAC/KID | 34F11BAC8E5390B57F4E601372339E3C |
++----------------+---------+----------------------------------+
+| 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.

+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                                                         |
++================+=========+==================================================================+
+| 1              | ENC/KIC | 542C37A6043679F2F9F71116418B1CD5542C37A6043679F2F9F71116418B1CD5 |
++----------------+---------+------------------------------------------------------------------+
+| 2              | MAC/KID | 34F11BAC8E5390B57F4E601372339E3C34F11BAC8E5390B57F4E601372339E3C |

++----------------+---------+------------------------------------------------------------------+
+
+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                         |
++================+=========+==================================+
+| 1              | TLS-PSK | 000102030405060708090a0b0c0d0e0f |
++----------------+---------+----------------------------------+
+| 2              | DEK/KIK | 000102030405060708090a0b0c0d0e0f |
++----------------+---------+----------------------------------+
+
+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

@@ -170,6 +170,35 @@ ensures that a message can only be sent once.
 .. note:: The replay-protection-counter is implemented as a 5 byte integer value (see also ETSI TS 102 225, Table 3).
 	  When the counter has reached its maximum, it will not overflow nor can it be reset.
 
+Expanded remote application data format
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+`smpp-ota-tool` uses the TS 102 226 section 5.1 compact remote application data format by default. This
+format concatenates C-APDUs into one command string and only the result of the LAST executed command is reported back.
+Retrieving the response data therefore requires a GET RESPONSE C-APDU, and only a single GET RESPONSE command may occur per script.
+
+The TS 102 226 section 5.2 expanded remote application data format removes these limitations: Each C-APDU is
+wrapped in its own C-APDU TLV inside a Command Scripting template, and the response is a Response Scripting template that contains one R-APDU TLV with the full response data and status word per executed command. To use it, pass
+``--format expanded``; every ``--apdu`` argument then becomes its own C-APDU TLV.
+
+.. note:: The expanded format does not use GET RESPONSE. To retrieve response data from a case 2 or case 4
+	  command, include an ``Le`` field in the C-APDU. i.e. ``Le='00'`` instructs the card to return all available
+	  response data in the R-APDU, with no 256-byte limit (TS 102 226, section 5.2.1.1). Without the ``Le``
+	  field no response data is returned, except a status word for the last command!.
+
+For example, a GP GET STATUS of all applications (``80F24002024F00``) returns a registry that can be much
+larger than 256 bytes. In the compact format the card would only answer with ``61xx`` procedure bytes. In the expanded
+format, appending ``Le='00'`` (i.e. ``80F24002024F0000``) makes the card return the whole registry in one exchange:
+
+::
+
+   $ PYTHONPATH=./ ./contrib/smpp-ota-tool.py --kic <KIC> --kid <KID> --kid-idx 1 --kic-idx 1 \
+       --algo-crypt triple_des_cbc2 --algo-auth triple_des_cbc2 --tar 000000 --cntr-req no_counter \
+       --format expanded --apdu 80F24002024F0000
+
+The response data (a concatenation of GlobalPlatform registry TLVs) can then be decoded with
+``pySim.global_platform.GpRegistryRelatedData.from_tlv()``.

+
+    A large user-data payload (e.g. a big OTA response packet) is split by the
+    sending entity into several SMS,
+    each carries a
+    - "concat short messages" IE in its UDH that identifies the set (ref num),
+    - total number of parts
+    - this parts seqno.
+    supports both:
+    IEI 0x00, section 9.2.3.24.1 8-bit ref form
+    IEI 0x08, section 9.2.3.24.8 the 16-bit ref form
+
+    Feed each received TP-User-Data (UDH + payload) to add() which
+    returns the reassembled TP-User-Data once all parts of the set have arrived,
+    or None as long as parts are still missing.
+
+    A non-concatenated SMS is returned unchanged,
+    just like one where the concat IE holds a reserved value:
+    TS 23.040 9.2.3.24.1 says
+    - both a total of zero
+    - a sequence number that is zero or greater than the total
+    that "the receiving entity shall ignore the whole IE",
+    we treat the message as a single, non-concatenated one and warn, not
+    as an error, so the caller does not die.
+
+    The reassembled TP-User-Data is built with a UDH that contains
+    the non-concat IEs seen in the parts, for example the the OTA "response packet"
+    indicator IE 0x71, followed by the concatenated payloads in sequence order,
+    so exactly the single-SMS form the sender would have produced for a payload that fits
