Implementation of the Skein hash function, one of the finalists in the SHA-3 competition
Project description
- PySkein is an extension module for Python, implementing the
Skein hash algorithm, one of the finalists in the NIST SHA-3 Competition. While originally based on the optimized version of the reference implementation by Doug Whiting, PySkein is now feature complete and offers a pythonic interface, all released as free software under the GNU General Public License. Its highlights are:
Simple interface following the hash algorithms in the Python standard library (like hashlib.sha1 or hashlib.sha256)
All features of the Skein specification (flexible digest sizes, MAC generation, tree hashing, and various other arguments)
High performance through optimized C implementation (7.1 cycles/byte for sequential hashing and 4.2 cycles/byte for tree hashing on two cores, measured on an Athlon 64 X2)
Threefish, the tweakable block cipher used in Skein, available for encrytion and decryption on its own
