SCryptUtil

SCrypt util scala adaption for Will Glozer's (@wg on github) SCryptUtil, improving on SHA1PRNGs, bad security in particular.

SCrypt described here: http://www.tarsnap.com/scrypt.html

The hashed output is an extended implementation of the Modular Crypt Format that also includes the scrypt algorithm parameters.

Format: $s0$PARAMS$SALT$KEY.

<dl>

PARAMS

<dt>32-bit hex integer containing log2(N) (16 bits), r (8 bits), and p (8 bits)</dt>

SALT

<dt>base64-encoded salt</dt>

KEY

<dt>base64-encoded derived key</dt> </dl>

s0 identifies version 0 of the scrypt format, using a 128-bit salt and 256-bit derived key.
