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.
