The Skein Hash Function Family

Keep them coming!

Alberto Fajardo has an implementation in .NET that is tuned for speed. Take a look at http://code.google.com/p/skeinfish/.

Sriram Krishnan has done a managed implementation of Skein in .NET, which is available on his blog at http://www.sriramkrishnan.com/blog/2009/08/nskein-skein-implementation-net.html.

The Botan C++ crypto library now includes Skein-512. http://botan.randombit.net/news/releases/1_8_3.html

Martin Kausche has done a Skein implementation in Ada, too.

We have released the final (V1.0, 29 April 2009) version of the Skein Proofs paper. It is available from the downloads page, or directly from <http://www.skein-hash.info/sites/default/files/skein-proofs.pdf>.

Daniel Otte has created an implementation of Skein for the AVR microcontroller. The implementation can be found at http://www.das-labor.org/wiki/AVR-Crypto-Lib/en and is licensed under GPLV3.

Thomas Mueller's Skein-512 Java code got ported to C#/.NET. The
code's available here:

In our Skein paper, we reference an unpublished paper detailing Skein's proofs of security.

A draft of that paper is now available at:

http://www.skein-hash.info/sites/default/files/skein-proofs.pdf.

We'll update it with the final paper soon.

Men Long has a paper on implementing Skein on the Xilinx Vertex-5 FPGA system. You can find the paper from the downloads page, or directly from this link.

The folks at Galois have come up with an implementation of Skein using their Cryptol language. Their article is here.

Thank you to Sigbjorn Finne, who did the article and likely the implementation, and Sally Browning, who told us about it.
