NIST has put up its official list of 51 round one candidates.
Ewan Fleischmann, Christian Forler, and Michael Gorski have done a classification of the candidates. Their article is up on the IACR ePrint Archive, amusingly, it is article #511 for the year.
There is another Java implementation of Skein-512-512 by the H2 Database folks.
I got this report today. The Intel C++ v11 compiler gives better code than Doug's assembler.
Maarten Bodewes has created an implementation of Skein in Java. It matches our test vectors. You can find his page here.
There are two bugs in the Skein code. They are subtle and esoteric, but they're there. We have revised both the reference and optimized code -- and provided new test vectors. A revision of the paper -- Version 1.1 -- has new IVs, new test vectors, and also fixes a few typos in the paper. There is also a revised version of the NIST submission CD.
A web site called The SHA-3 Zoo can be found at http://ehash.iaik.tugraz.at/wiki/The_SHA-3_Zoo. It has lists of all SHA-3 submissions, including Skein.
