Webyescrypt - scalable KDF and password hashing scheme. yescrypt is a password-based key derivation function (KDF) and password hashing scheme. It builds upon Colin Percival's scrypt. This implementation is able to compute native yescrypt hashes as well as classic scrypt. For a related proof-of-work (PoW) scheme, see yespower instead. http://www.iotword.com/4472.html
