Yawning / elligator2.h
Last active Mar 20, 2020
(DEPRECATED) A mostly drop in elligator2 for ed25519-donna.
View elligator2.h
There used to be something that resembled an Elligator2 implementation here ported from agl's
Go code. The implementation is unmaintained and has severe issues (as pointed out in a comment),
and should not be used for anything.
