scrypt
scrypt (crystal)
Crystal bindings for Colin Percival's scrypt library.
The scrypt key derivation function was originally developed for use in the Tarsnap online backup system and is designed to be far more secure against hardware brute-force attacks than alternative functions such as PBKDF2 or bcrypt.
