pake vs spake2 vs srp

Traits which describe the functionality of [Password-Authenticated Key Exchange] (PAKE) algorithms, which can be used to establish a shared secret over an insecure channel using only the client's knowledge of a password and the server's knowledge of a password hash for authentication, without the client revealing their plaintext password to the server

The SPAKE2 password-authenticated key-exchange algorithm.

Pure Rust implementation of the Secure Remote Password (SRP) password-authenticated key exchange (PAKE) algorithm as described in RFC5054. Built on `crypto-bigint`, a mathematical library designed with constant-time algorithms.
