+pysha3
+======
+
+SHA-3 wrapper (keccak) for Python. 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()

+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. The old Keccak hashes are available with
+ keccak prefix.
+
+- Add SHAKE support.
+
+- All sha3, shake and keccak variants are separate types instead of factory
+ functions that return the same type.
+
+- Drop Python 2.6 and Python 3.0 to 3.3 support.
+
+- Fix typo that disabled threading optimization.
+
+- Add vector files for additional tests.
+
+- Add experimental HMAC support based on examples from
+ http://wolfgang-ehrhardt.de/hmac-sha3-testvectors.html .
+
+- Test hashing of unaligned data.
+
+- Add ISO C11 memset_s() function as _Py_memset_s() in order to securely
+ wipe memory that holds sensitive data. The page
+ https://www.securecoding.cert.org/confluence/display/seccode/MSC06-C.+Be+aware+of+compiler+optimization+when+dealing+with+sensitive+data
+ explains the motivation for memset_s().
+
+- Add tox support.
+
+- Add Travis and appveyor integration.
+
+- Add _capacity_bits, _rate_bits and _suffix attributes for diagnostic
+ purposes.
+
+
+pysha3 0.3
+----------
+
+*Release date: 14-Oct-2012*
+
+- Fix 64bit big endian support
+
+- Add workaround for alignment error on 64bit SPARC machine by using the opt32
+ implementation.
+
+- block_size now returns NotImplemented to prevent users from using pysha3
+ with the hmac module.
+
+
+pysha3 0.2.2
+------------
+
+*Release date: 07-Oct-2012*
+
+- Re-add brg_endian.h to fix issue on Solaris (big endian platform)
+
+

+------------
+
+*Release date: 06-Oct-2012*
+
+- Fix MANIFEST.in to include Makefile and tests.py
+
+- Add setup.py test command with hack for inplace builds
+
+- Enhance README.txt and fixed its markup
+
+
+pysha3 0.2
+----------
+
+*Release date: 06-Oct-2012*
+
+- Change directory struct to use the same directory layout as Python 3.4.
+
+- Remove C++ comments from Keccak sources for ANSI C compatibility.
+
+- Declare all Keccak functions and globals as static to avoid name clashes.
+
+- Remove alias sha3() for sha3_512().
+
+- Add block_size attribute. Keccak has a internal sponge size of 1600 bits.
+

+
+- Monkey patch the hashlib module to support, e.g. hashlib.sha3_512() and
+ hashlib.new("sha3_512")
+
+- Release GIL around SHA3_update() when the data exceeds a certain size.
+
+- Fix build on platforms with an unsigned 64bit integer type (uint64_t). The
+ module falls back to 32bit implementation of Keccak with interleave tables.
+
+
+pysha3 0.1
+----------
+
+*Release date: 04-Oct-2012*
