collection of crypto hashes, fast, pure and practical

 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.
 .
 This package provides a library for the Haskell programming language.
 See http://www.haskell.org/ for more information on Haskell.
