Skein [1] is a family of fast secure cryptographic hash functions. This package uses bindings to the optimized C implementation of Skein. There is a high-level interface provided to some of the Skein use cases, and a low-level interface when Skein has to be used in a different way. Currently Skein is supported as cryptographic hash function as Skein as a message authentication code (Skein-MAC). [1] http://www.skein-hash.info/ WWW: https://github.com/meteficha/skein
