In particular, this release includes a complete proof of type-safety for the implementation, test cases for structural coverage, performance, and the reference test vectors from the Skein specification. Performance is very close to that of the C reference implementation. Check it out at www.skein-hash.info There's also a technical paper describing the implementation and results, available from the same place. - Rod Chapman, SPARK Team, Altran Praxis
