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.
Using Shards, add the scrypt dependency
shard.yml then run
dependencies: scrypt: github: ysbaddaden/scrypt-crystal
If you're not using Shards, you may clone the repository then run
make lib to
download and compile the
require "scrypt" # hash hashed_password = Scrypt::Password.create("super awesome") # compare hashed_password == "super awesome" # => true hashed_password == "super wrong" # => false
