SPAKE2 password-authenticated key exchange (in pure python).
This library implements the SPAKE2 password-authenticated key
exchange ("PAKE") algorithm. This allows two parties, who share a
weak password, to safely derive a strong shared secret (and
therefore build an encrypted+authenticated channel).
