-- | A bcrypt implementation for haskell
--   
--   Wraps around the OpenBSD blowfish implementation to implement bcrypt.
--   
--   A slightly modified (for build purposes) bcrypt c library is included.

module Data.Digest.BCrypt

-- | Hash a password based on a BSalt with a given cost
bcrypt :: ByteString -> BSalt -> ByteString

-- | Given a cost from 4-32 and a random seed of 16 bytes generate a salt.
--   Seed should be 16 bytes from a secure random generator
genSalt :: Integer -> ByteString -> Maybe BSalt

-- | Given a bytestring, construct a BSalt type, with some minimal checking
packBSalt :: ByteString -> Maybe BSalt

-- | BCrypt salt for passing to bcrypt.
