Skein Home
Here's an implementation of version 1.3 of the Skein cryptographic hash function. (To Linux-libre
aid in pronunciation the name rhymes with rain and Spain.) It uses the reference
implementation provided by Bruce Schneier on his website.

Skein was one of the finalists in the NIST competition to develop a new hash function
called SHA-3. Skein made it all the way through to the end but was ultimately not How To
selected. There was a later announcement that the winner, Keccak, would have some
changes made so as to increase performance but some saw these changes as Articles
weakening it. Given that we know the NSA has played a role in weakening
cryptographic standards, some wondered if this was such an attempt. Regardless of RSS Feed
whether it was or not, the fact that there was such a huge uproar over the changes
goes to show just how little trust there is of the NSA and NIST.
About Me
I'm not necessarily proposing that anyone not use NIST standards but at the same
time, my interest in Skein comes specifically because it was not selected by NIST. Contact Me
While Skein can be used as a drop-in replacement for the entire SHA family of hash
functions perhaps using multiple cryptographic hashes would be a good defense GPL enforced
against any one of them being compromised, so here's one.
