Go implementation of bcrypt_pbkdf(3) from OpenBSD (a variant of PBKDF2 with bcrypt-based PRF). USAGE func Key(password, salt []byte, rounds, keyLen int) ([]byte, error) Key derives a key from the password, salt and rounds count, returning a []byte of length keyLen that can be used as cryptographic key. Remember to get a good random salt of at least 16 bytes. Using a higher rounds count will increase the cost of an exhaustive search but will also make derivation proportionally slower.
