I've been quietly maintaining a Linux kernel implementation of the
'skein' hash algorithm, which is one of the proposed SHA-3 algorithms.
First posted around two years ago:

Skein is currently at version 1.3, and as slashdot readers are aware,
skein is one of the finalists for SHA-3.
The git URL remains unchanged: branch "skein" of
git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/misc-2.6.git
Thanks to Tobias Karnat for recent updates, including conversion to shash.
