Harald Welte 721ba9b31f tests: Add new, data-driven OTA tests
Rather than writing one test class with associated method for each
OTA algorithm / test, let's do this in a data-driven way, where new
test cases just have to provide test data, while the code iterates over
it.

This is important to produce the right command syntax when generating

this kludge to the individual programs, but only to the documentation
using the :prog: syntax.

Harald Welte f9a5ba5e0f 31.102: Fix EF.Routing_Indicator for odd number of digits
The routing indicator is BCD-encoded but has an arbitrary length of
1, 2, 3 or 4 digits.

In order to support the odd lengths of 1 or 3, we must not pad on the
byte level, but on the nibble level. This requires a slight extension of
the Rpad() Adapter.

Harald Welte d75fa3f7c9 Switch from pycryptodome to pycryptodomex
So for some weird historical reasons, the same python module is
available as pycryptodome (Crypto.* namespace) and pycryptodomex
(Cryptodome.* namespace).  See the following information on the project
homepage: https://www.pycryptodome.org/src/installation

To make things extra-weird, Debian choose to package pycryptodomex as
python3-pycryptodome
(https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=886291).

So in order to support both Debian-packaged and differently-installed
packages, let's switch to pycryotodomex on all platforms/installers.

Harald Welte 219a5f369c OTA: Fix padding of AES CMAC
When using AES CMAC for authentication of OTA messages, we must not pad
the user data before calling the CMAC function. This is unlike the DES
MAC, where padding to the DES block size is mandatory.

This bug was discovered when trying to talk OTA with AES to a
sysmoISIM-SJA5.  This patch makes the OTA AES interoperate with the
card.  Also, with this patch the cryptographic results of pySim/ota.py
are identical to those of the java code

stores the information required for SUCI calculation, the
TCA/SIMalliance standard is the only standard there is.  Some CardOS
start to use this standard even for non-eSIM/eUICC use cases.

As a result, code like 'read_records' now knows the number of records
and can iterate over them rather than raising exceptions.

Harald Welte 6bf2d5f216 gsm_r: EF_Predefined: Decode first record different from others
In their infinite wisdom, the authors of the EIRENE FFFIS for GSM-R SIM
cards invented yet a new way of encoding data in SIM card files: The
first record of a file may be encoded differently than further records
of files.

This patch implements the feature based on the newly-introduced way by
which we pass the record number to the encoder and decoder methods.

This allows for some more obscure TLV parsers, such as the upcoming one
for Proactive Commands in the CAT/OTA context.

Harald Welte 21caf32e3d Introduce APDU/TPDU trace decoder
This introduces a new pySim.apdu module hierarchy, which contains
classes that represent TPDU/APDUs as exchanged between
SIM/UICC/USIM/ISIM card and UE.

It contains instruction level decoders for SELECT, READ BINARY and
friends, and then uses the pySim.filesystem.Runtime{Lchan,State} classes
to keep track of the currently selected EF/DF/ADF for each logical
channel, and uses the file-specific decoder classes of pySim to decode
the actual file content that is being read or written.

This provides a much more meaningful decode of protocol traces than
wireshark will ever be able to give us.

Furthermore, there's the new pySim.apdu_source set of classes which
provides "input plugins" for obtaining APDU traces in a variety of
formats.  So far, GSMTAP UDP live capture and pyshark based RSPRO
live and pcap file reading are imlpemented.
