Hello list,
A while ago, I've created a Whirlpool hash function library [1] based on the original implementation of Whirlpool algorithm by Vincent Rijmen and Paulo S. L. M. Barreto.
It's packaged as 'libwhirlpool' in Fedora and EPEL [2].
Also provides 'whirlpoolsum' utility to calculate and check Whirlpool hashes with the interface similar to 'md5sum', 'shaXXXsum' from coreutils.
