ValueError: [digital envelope routines: EVP_MD_CTX_copy_ex] input not
initialized
The critical place is
hashlib.pbkdf2_hmac(digest().name, password, salt, iterations, dklen)
in crypto.py
I tried the same function manually in a Python terminal with the identical
arguments:
hashlib.pbkdf2_hmac('sha256', 'XXXXX', 'XXXXX', 36000, None)
It works OK. But if I call it in the same fashion anywhere in Django
project it causes the exception.
