Dear Freeradius developers:
I am now doing research using Freeradius Server and I have to add some
functions based on the source code. I have several questions and need your
1. In which variable (and in which file) in the source code is the session
key (or TEK) stored after successful authentication? I have to use it. In
the src/modules/rlm_eap/libeap/eapcrypto.c file, eapsim_calculate_keys()
produces 4 other keys after ek->master_key is calculated. Is one of them
used as the session key? And where is the session key if PAP authentication
2. What symmetric-key encryption/decryption algorithm (like AES, Twofish, or
others) is used? And where is it in the source code?
3. If I want to generate a key from a random integer, is it proper to use
Thanks for your help.
Regards, Hao Wang
