Hi Jouni/list,
Wanted a clarification on the internal crypto implementation of supplicant (crypto_internal)

The function crypto_mod_exp() expects a big endian byte array (lowest byte at the highest index) as input. But I noticed that when crypto_mod_exp() is called from dh_init() the generator, private key and prime byte arrays are all in little endian format ? (I might have missed something obvious, please correct me) 

Is the result pointer that is output from crypto_mod_exp() in little endian or big endian format ?
