Implementation of the Skein hash function

PySkein is an extension module for Python 3.0 or later implementing the Skein hash algorithm, one of the Second Round Candidates in the NIST SHA-3 Competition. While originally based on the optimized version of the reference implementation by Doug Whiting, PySkein has since evolved into a feature-rich and pythonic module. It is released as free software under the GNU General Public License. Its highlights are:

• A simple interface following the hash algorithms in the Python standard library (like hashlib.sha1 or hashlib.sha256)

• High hashing performance through efficient implementation in C (368 MB/s on a 2.8 GHz Opteron)

• Many features of the Skein specification (such as tree hashing, various parameters and output sizes etc.)

• Threefish, the tweakable block cipher used in Skein, available for encrytion and decryption on its own

New in version 0.6: Tree hashing with arbitrary tree parameters
