-- | Password Based Key Derivation Functions:
--   This module provides stock implementations of the PBKDF functions from
--   RFC-2898 based on the SHA-1, SHA-256 and SHA-256 hash functions. Each
--   function takes the password and salt as a string and returns a hex
--   string. To work with ByteStrings and provide your own hash and
--   psuedo-random use the Crypto.PBKDF.Core that are used to implement
--   these functions.
