module BCryptPbkdf
# generates a key from a password + salt returning a string with keylen bytes
# 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.
#
# Example:
# rounds = 10
# keylen = 64
# @key = BCryptPbkdf.key("my secret", "my salt", keylen, rounds)
