------------------------------------------------------------------------
KeyGenerator is a simple wrapper around OpenSSL's implementation of
PBKDF2. It can be used to derive a number of keys for various purposes
from a given secret. This lets Rails applications have a single secure
secret, but avoid reusing that key in multiple incompatible contexts.
