TL;DR

ClojureWerkz Scrypt is a tiny Clojure library for working with scrypt, a key derivation function. Scrypt can be used to hash passwords and generate cryptographic keys. It is an alternative to Bcrypt and PBKDF2.

Why Use Scrypt

Values (e.g. passwords) encrypted with Scrypt are much more computationally hard to crack than with most other available key derivation functions:

More can be found in the scrypt paper.

What’s In The Box

Scrypt is literally a couple of functions:

• Encrypt a value (e.g. a password)
• Verify a candidate against a hash (e.g. against a password used to authenticate)

Documentation

Scrypt is a small library and all of its documentation guide fits in the README.

Supported Clojure Versions

Scrypt supports Clojure 1.3+.
