7cadab94f8 esim/http_json_api.py: support text/plain response Content-Type
Allow returning text/plain Content-Types as 'data' output argument.

So far, all the esim/http_json_api functions require a JSON response.
However, a specific vendor has a list function where the request is JSON
but the response is text/plain CSV data. Allow and return in a dict.

f62ae7bd17 saip: add numeric_base indicator to ConfigurableParameter
By default, numeric_base = None, to indicate that there are no explicit
limitations on the number space.

For parameters that are definitely decimal, set numeric_base = 10.
For definitely hexadecimal, set numeric_base = 16.

Do the same for ConfigurableParameter as well as ParamSource, so callers
can match them up: if a parameter is numeric_base = 10, then omit
sources that are numeric_base = 16, and vice versa.

ee03065663 saip SmspTpScAddr: safeguard against decoding error
Reading the TS48 V6.0 eSIM_GTP_SAIP2.1A_NoBERTLV profile results in an
exception [1] in SmspTpScAddr. I have a caller that needs to skip
erratic values instead of raising.

The underlying issue, I presume, is that either the data needs
validation before decode_record_bin(), or decode_record_bin() needs
well-defined error handling.

So far I know only of this IndexError, so, as a workaround, catch that.

9f18a0ff56 personalization audit: optionally audit all (unknown) SD keys
By a flag, allow to audit also all Security Domain KVN that we have
*not* created ConfigurableParameter subclasses for.

For example, SCP80 has reserved kvn 0x01..0x0f, but we offer only
Scp80Kvn01, Scp80Kvn02, Scp80Kvn03. So we would not show kvn
0x03..0x0f in an audit.

This patch includes audits of all SD key kvn there may be in the UPP.
This will help to spot SD keys that may already be present in a UPP
template, with unexpected / unusual kvn.

bd358a2621 personalization: fix SdKey.apply_val() implementation
'securityDomain' elements are decoded to ProfileElementSD instances,
which keep higher level representations of the key data apart from the
decoded[] lists.

So far, apply_val() was dropping binary values in decoded[], which does
not work, because ProfileElementSD._pre_encode() overwrites
self.decoded[] from the higher level representation.

Implement using
- ProfileElementSD.find_key() and SecurityDomainKeyComponent to modify
  an exsiting entry, or
- ProfileElementSD.add_key() to create a new entry.

Before this patch, SdKey parameters seemed to patch PES successfully,
but their modifications did not end up in the encoded DER.

(BTW, this does not fix any other errors that may still be present in
the various SdKey subclasses, patches coming up.)

1f50f29546 personalization: indicate default ParamSource per ConfigurableParameter
Add default_source class members pointing to ParamSource classes to all
ConfigurableParameter subclasses.

This is useful to automatically set up a default ParamSource for a given
ConfigurableParameter subclass, during user interaction to produce a
batch personalization.

For example, if the user selects a Pin1 parameter, a calling program can
implicitly set this to a RandomDigitSource, which will magically make it
work the way that most users need.

BTW, default_source and default_value can be combined to configure a
matching ParamSource instance:

  my_source = MyParam.default_source.from_str( MyParam.default_value )

1e0b3b35d4 personalization: implement reading back values from a PES
Implement get_values_from_pes(), the reverse direction of apply_val():
read back and return values from a ProfileElementSequence. Implement for
all ConfigurableParameter subclasses.

Future: SdKey.get_values_from_pes() is reading pe.decoded[], which works
fine, but I07dfc378705eba1318e9e8652796cbde106c6a52 will change this
implementation to use the higher level ProfileElementSD members.

Implementation detail:

Implement get_values_from_pes() as classmethod that returns a generator.
Subclasses should yield all occurences of their parameter in a given
PES.

For example, the ICCID can appear in multiple places.
Iccid.get_values_from_pes() yields all of the individual values. A set()
of the results quickly tells whether the PES is consistent.

Rationales for reading back values:

This allows auditing an eSIM profile, particularly for producing an
output.csv from a batch personalization (that generated lots of random
key material which now needs to be fed to an HLR...).

Reading back from a binary result is more reliable than storing the
values that were fed into a personalization.
By auditing final DER results with this code, I discovered:
- "oh, there already was some key material in my UPP template."
- "all IMSIs ended up the same, forgot to set up the parameter."
- the SdKey.apply() implementations currently don't work, see
  I07dfc378705eba1318e9e8652796cbde106c6a52 for a fix.

The tuples defining a DF or ADF in an eSIM template must contain a

must save it, and re-create it at the time we re-encode that file.

Same applies to the lcsi (life cycle state indicator), which may
optionally exist for any file.

8ee10ab1a5 tests/pySim-smpp2sim_test/card_sanitizer: update card backup with new test keyset
In our test setup we run the card_sanitizer.py script regualary to ensure that
we have consistent start conditions when running our tests. In case a testcase
crashes for some reason and leaves messed up files on a test card. The
card_sanitizer.py script will ensure that any problem like that is cleaned up
over night.

For the testcases we are about to add in the patch following this one, we need
to provision a new test keyset to one of our test cards. This has been already
done manually. However since the card_sanitizer still has the old keys in its
backup we will have to update that as well.

f10af30aed global_platform/scp: fix dek_encrypt/dek_decrypt for SCP02
The methods dek_encrypt/dek_decrypt use the wrong algorithm and the
wrong key material. The algorithm should be 3DES rather then single
DES and the key must be the DEK session key instead of the static
DEK key from which the DEK session key is derived.

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.
