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.

Version 1.1.0 makes it possible to use a native scrypt implementation.

Changes Between 1.0.0 and 1.1.0

Lambdaworks Scrypt Upgrade

Lambdaworks Scrypt is updated to 1.4.0, which makes it possible to use a native implementation of the library.

To quote the docs:

6

The system property "com.lambdaworks.jni.loader" may be set to override
the default native library loader with one of the following values:

 * nil: refuse to load native libraries and revert to pure Java implementation
 * jar: extract native library from jar and load with System.load
 * sys: use System.loadLibrary, which may require java.library.path to be set

Clojure 1.3 Support Dropped

Scrypt no longer officially supports Clojure 1.3.
