Log Message:
A collection of crypto hashes, with a practical incremental and one-pass,
pure APIs, with performance close to the fastest implementations available
in others languages.

The implementations are made in C with a haskell FFI wrapper that hide the
C implementation.

Simple examples using the unified API:
 import Crypto.Hash

 sha1 :: ByteString -> Digest SHA1
 sha1 = hash

 hexSha3_512 :: ByteString -> String
 hexSha3_512 bs = show (hash bs :: Digest SHA3_512)

Simple examples using the module API:
 import qualified Crypto.Hash.SHA1 as SHA1

 main = putStrLn $ show $ SHA1.hash (Data.ByteString.pack [1..256])

 import qualified Crypto.Hash.SHA3 as SHA3

 main = putStrLn $ show $ digest
   where digest = SHA3.finalize ctx
         ctx    = foldl' SHA3.update iCtx (map Data.ByteString.pack [ [1,2,3], \ 
[4,5,6] ]
         iCtx   = SHA3.init 224
