SIM card related Projects » pySim

Hi,

With last master version, I have an issue regarding Crypto.AES when writing an USIM (with Ki and Op), using pycrypto or pycryptodome:

./pySim-prog.py -p 0 -a xxxx -x xxx -y xxx -i xxxx -s xxx --op=xxx -k xxxx --acc=xxx -n xxx

• With pycrypto, the error is:

Card programming failed with an execption:

Traceback (most recent call last):

    cp = gen_parameters(opts)

    opc = derive_milenage_opc(ki, opts.op)

TypeError: argument 1 must be read-only bytes-like object, not bytearray

• With pycryptodome, the error is:

Programming failed: Remove card from reader

In both case, it doesnt work !
