AES256 encryption.

#2829 (Feb 23, 2026, 6:02:44 PM)

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.)

#2828 (Feb 23, 2026, 5:47:25 PM)

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.

#2827 (Feb 23, 2026, 5:32:10 PM)

personalization: make AlgorithmID a new EnumParam

The AlgorithmID has a few preset values, and hardly anyone knows which
is which. So instead of entering '1', '2' or '3', make it work with
prededined values 'Milenage', 'TUAK' and 'usim-test'.

Implement the enum value part abstractly in new EnumParam.

Make AlgorithmID a subclass of EnumParam and define the values as from
pySim/esim/asn1/saip/PE_Definitions-3.3.1.asn

#2823 (Feb 23, 2026, 4:00:53 PM)

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 )

contrib/smpp-ota-tool: warn about mixed up KIC/KIC indexes

Cards usually have multiple sets of KIC, KID (and KIK). The keys
are selected through an index. However, mixing keys from different
sets is concidered as a security violation and cards should reject
such configurations.

Let's print a warning to make users aware that something is off.

esim/http_json_api: add alternative API interface

unfortunately the API changes introduced in change

I277aa90fddb5171c4bf6c3436259aa371d30d092

broke the API interface of http_json_api.py. This was taken into
account and necessary to introduce add the server functionality next
to the already existing client functionality. The changes to the API
were minimal and all code locations that use http_json_api.py
were re-aligned.

Unfortunately it was not clear at this point in time that there are
out-of-tree projects that could be affected by API changes in
http_json_api.py

To mitigate the problem this patch introduces an alternative API
interface to the JsonHttpApiFunction base class. This alternative
API interface works like the old API interface when the class is
instantiated in the original way. To make use of the revised client
the API use has to pass an additional keyword argument that defines
the role.

esim/http_json_api: add alternative API interface

unfortunately the API changes introduced in change

I277aa90fddb5171c4bf6c3436259aa371d30d092

broke the API interface of http_json_api.py. This was taken into
account and necessary to introduce add the server functionality next
to the already existing client functionality. The changes to the API
were minimal and all code locations that use http_json_api.py
were re-aligned.

Unfortunately it was not clear at this point in time that there are
out-of-tree projects that could be affected by API changes in
http_json_api.py

To mitigate the problem this patch introduces an alternative API
interface to the JsonHttpApiFunction base class. This alternative
API interface works like the old API interface when the class is
instantiated in the original way. To make use of the revised client
the API use has to pass an additional keyword argument that defines
the role.

tests/pySim-smpp2sim_test: add integration test

At the moment pySim.ota codebase is not covered by any of the
integration tests (we have only normal unittests so far). To
increase the test coverage, let's add an integration test that
sends exchanges an RFM OTA-SMS with a real-world card.

However, there is no tool avaliable that can be used as an SMPP
client for pySim-smpp2sim yet. Let's use smpp_ota_apdu2.py on
laforge/ota to develop a tool that we can use to exchange SMS-TPDUs
that contain remote APDU scripts (RFM/RAM).

Finally let's use the tool we have created as a basis to create
an integration test that exchanges an SMS-TPDU with the RFM
application of a sysmoISIM-SJA5 card. The testcase shall pass
when we get the expected response from the card.

[2/7] personalization: refactor ConfigurableParameter, Iccid, Imsi

Main points/rationales of the refactoring, details below:
1) common validation implementation
2) offer classmethods

The new features are optional, and will be heavily used by batch
personalization patches coming soon.

Implement Iccid and Imsi to use the new way, with a common abstract
DecimalParam implementation.

So far leave the other parameter classes working as they always did, to
follow suit in subsequent commits.

Details:

1) common validation implementation:
There are very common validation steps in the various parameter
implementations. It is more convenient and much more readable to
implement those once and set simple validation parameters per subclass.
So there now is a validate_val() classmethod, which subclasses can use
as-is to apply the validation parameters -- or subclasses can override
their cls.validate_val() for specialized validation.
(Those subclasses that this patch doesn't touch still override the
self.validate() instance method. Hence they still work as before this
patch, but don't use the new common features yet.)

2) offer stateless classmethods:
It is useful for...
- batch processing of multiple profiles (in upcoming patches) and
- user input validation
to be able to have classmethods that do what self.validate() and
self.apply() do, but do not modify any self.* members.
So far the paradigm was to create a class instance to keep state about
the value. This remains available, but in addition we make available the
paradigm of a singleton that is stateless (the classmethods).
Using self.validate() and self.apply() still work the same as before
this patch, i.e. via self.input_value and self.value -- but in addition,
there are now classmethods that don't touch self.* members.
