• File pySim/esim/saip/personalization.py:

  • Patch Set #3, Line 551: allow_len = int(128/8) # length in bytes (from BinaryParam)

    You mean the length of 128 bit? I have no idea!! Will have to check, thanks! […]

    just look at the pysim-shell code for setting the values on a sysmoISIM card:

            # TUAK has a rather different layout for the data, so we define a different
            # construct below and use explicit _{decode,encode}_bin() methods for separating
            # the TUAK and non-TUAK situation
            CfgByteTuak = BitStruct(Padding(1),
                                    'key_length'/Mapping(Bit, {128:0, 256:1}),
                                    'sres_deriv_func_in_2g'/Mapping(Bit, {1:0, 2:1}),
                                    'use_opc_instead_of_op'/Mapping(Bit, {False:0, True:1}),
                                    'algorithm'/Algorithm)
            TuakCfgByte = BitStruct(Padding(1),
                                    'ck_and_ik_size'/Mapping(Bit, {128:0, 256:1}),
                                    'mac_size'/Mapping(BitsInteger(3), {64:0, 128:1, 256:2}),
                                    'res_size'/Mapping(BitsInteger(3), {32:0, 64:1, 128:2, 256:3}))
