haskell Skein (<http://www.skein-hash.info/>) is a family of fast secure cryptographic hash functions designed by Niels Ferguson, Stefan Lucks, Bruce Schneier, Doug Whiting, Mihir Bellare, Tadayoshi Kohno, Jon Callas and Jesse Walker. This package uses bindings to the optimized C implementation of Skein. We provide a high-level interface (see module "Crypto.Skein") to some of the Skein use cases. We also provide a low-level interface (see module "Crypto.Skein.Internal") should you need to use Skein in a different way. Currently we have support for Skein as cryptographic hash function as Skein as a message authentication code (Skein-MAC). For examples of how to use this package, see "Crypto.Skein" module documentation. When manually selecting the endianness, use big-endian (default is little-endian). Use a manually selected endian when compiling (see flag 'big-endian'). Use the reference implementation instead of the optimized one. meteficha/skein
