PBKDF2 implements PBKDF2 (Password-Based Key Derivation Function 2), part of PKCS #5 v2.0 (Password-Based Cryptography Specification). It can be used to derive a number of keys for various purposes from a given secret. This lets applications have a single secure secret, but avoid reusing that key in multiple incompatible contexts. see http://tools.ietf.org/html/rfc2898#section-5.2
