The package is a wrapper around the +optimized Keccak Code Package, https://github.com/gvanas/KeccakCodePackage . + +The module is a standalone version of my SHA-3 module from Python 3.6 +(currently under development). The code in sha3module.c has been modified to +be compatible with Python 2.7 to 3.5. Python 2.6 and earlier are not +supported. + + +Updates since pysha 0.3 +======================= + +**pysha3 1.0 is not compatible with pysha3 0.3!** + +pysha3 < 1.0 used the old Keccak implementation. During the finalization of +SHA3, NIST changed the delimiter suffix from 0x01 to 0x06. The Keccak sponge +function stayed the same. pysha3 1.0 provides the previous Keccak hash, too. + + +Platforms +========= + +pysha3 has been successfully tested on several platforms: + + - Linux (GCC, clang) on X86, X86_64 and ARMv6 (little endian) + - Windows (VS 2008, VS 2010, VS2015) on X86 and X86_64 + + +Usage +===== + +The `sha3` module contains several constructors for hash objects with a +PEP 247 compatible interface. The module provides SHA3, SHAKE and Keccak: + +* `sha3_228()`, `sha3_256()`, `sha3_384()`, and `sha3_512()` +* `shake_128()`, `shake_256()` +* `keccak_228()`, `keccak_256()`, `keccak_384()`, and `keccak_512()` + +The `sha3` module monkey patches the `hashlib` module . The monkey patch is +automatically activated with the first import of the `sha3` module. The +`hashlib` module of Python 3.6 will support the four SHA-3 algorithms and +the two SHAKE algorithms on all platforms. Therefore you shouldn't use the +sha3 module directly and rather go through the `hashlib` interface:: + + >>> import sys + >>> import hashlib + >>> if sys.version_info < (3, 6): + ... import sha3 + >>> s = hashlib.sha3_512() + >>> s.name + 'sha3_512' + >>> s.digest_size + 64 + >>> s.update(b"data") + >>> s.hexdigest() + 'ceca4daf960c2bbfb4a9edaca9b8137a801b65bae377e0f534ef9141c8684c0fedc1768d1afde9766572846c42b935f61177eaf97d355fa8dc2bca3fecfa754d' + + >>> s = hashlib.shake_256() + >>> s.update(b"data") + >>> s.hexdigest(4) + 'c73dbed8' + >>> s.hexdigest(8) + 'c73dbed8527f5ae0' + >>> s.hexdigest(16) + 'c73dbed8527f5ae0568679f30ecc5cb6' + + >>> import sha3 + >>> k = sha3.keccak_512() + >>> k.update(b"data") + >>> k.hexdigest() + '1065aceeded3a5e4412e2187e919bffeadf815f5bd73d37fe00d384fe29f55f08462fdabe1007b993ce5b8119630e7db93101d9425d6e352e22ffe3dcb56b825' + +Changelog +========= + +pysha3 1.0.2 +------------ + +*Release: 05-Feb-2017* + +- Rename internal C extension to _pysha3 to avoild conflict with Python 3.6' + _sha3 extension. + +pysha3 1.0.1 +------------ + +*Release: 24-Jan-2017* + +- Fix github.org -> github.com (Pi Delport) + +- Fix endianness checks for Python 2 (William Grant) + +- Fix changelog, the Christmas release was 1.0.0, not 1.1.0 + +pysha3 1.0.0 +------------ + +*Release date: 24-Dec-2016* + +- Synchronize with Python 3.6.0 release + +- Move all backport related additions to backport.inc + +- Fix flake8 violations + + +pysha3 1.0b1 +------------ + +*Release date: 01-May-2016* + +- Update backend to use the latest Keccak Code Package. pysha3 now implements + the official NIST standard.
