Subject: mschapv2-conversion
I did following modifications and while debugging the program, it gets terminated in fmt_self_test() in crypt_all(). It is not able to do the DES encryption. I think that I may be compiling the program wrongly. I don't know what's the problem. I did following changes.
1. In MSCAHPv2_fmt_plug.c, in init(), DES_bs_init() is called with LM=2.
2. In DES_bs.c, DES_bs_init() changes done for option LM=2.
3. In MSCHAPv2_fmt_plug.c, mschapv2_set_salt(), challenge is set as plaintext in DES_bs_all.B.
4. MSCHAPv2_fmt_plug.c, mschapv2_crypt_all(), call to DES_bs_set_key() and DES_bs_crypt_one() is made.
5. In DES_bs_b.c, DES_bs_crypt_one() function is added.
I have not completed the conversion fully but was testing for fmt_self_test() which should be able to encrypt using DES_bs_crypt_one() but it terminates on reaching S1(....). I have attached the source files, where sections marked CHANGE are the changes I have done.
Cheers,
Deepika
