The [Whirlpool] algorithm is designed by Vincent Rijmen and Paulo S.L.M. Barreto.
It is a secure and modern digest function that has been recommended by the
[NESSIE] project and adopted in the ISO/IEC 10118-3 international standard.
Digest functions, also known as hash functions, produce fixed-length output (a
digest or hash) from a variable-length message. They are designed to be a
one-way function.
This library is a Python wrapper around the Whirlpool C reference implementation.
The Whirlpool reference implementations are public domain, as is this code.
The first version of the wrapper was written by James Cleveland with help
from #python on irc.freenode.net.
Later on the wrapper was rewritten by Olaf Conradi to use the hashlib interface
and he made the library compatible with Python 3.
## Installation
This library is available on [PyPI].
pip install whirlpool
## Usage
This is the same interface as provided by the other digest algorithms in
Python's hashlib.
import whirlpool
wp = whirlpool.new("My String")
hashed_string = wp.hexdigest()
wp.update("My Salt")
hashed_string = wp.hexdigest()
Starting with Python 3 text strings (as shown above) are stored as unicode.
You need to specify the encoding of these strings before hashing.
wp = whirlpool.new(data.encoding('utf-8'))
Strings that are marked as binary do not need encoding.
## Development
The source code is available on [GitHub].
git clone https://github.com/oohlaf/python-whirlpool.git
cd python-whirlpool
Install in development mode using:
python setup.py develop
Or install in editable mode using pip:
pip install -e .
## Testing
This module is tested using Python 2.7, PyPy, and Python 3.3 and up.
You can run the test suite using
python setup.py test

# Whirlpool Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog][keepachangelog] and this
project adheres to [Semantic Versioning][semver].
## [Unreleased]
## [1.0.0] (2018-02-19)
### Added
- Port to Python 3.
- Added PyPy support. PyPy3 does not work due to functions
that have not yet been ported (like missing `PyUnicode_New`).
- Added Continuous Integration using Travis CI and AppVeyor.
- Added automatic upload to PyPI for successful build tags. Proper
vX.Y.Z style tags upload to production PyPI, any other build
(including .devX appended) upload to Test PyPI.
### Fixed
- Fix struct function declaration prototype warnings.
- Fix pointer warnings.
### Changed
- Package ownership transferred to Olaf Conradi.
- Started using [Semantic Versioning][semver] together with
[Keep a Changelog][keepachangelog].
- Restructured the package setup and revamped build scripts.
### Deprecated
- Removed the old deprecated `hash()` interface.
## [0.3] (2013-01-23)
### Added
- Added the same interface as other Python digest algorithms have
(like the default `hashlib` module).
### Changed
- Created proper unit tests.
### Deprecated
- The `hash()` function is deprecated. Please transition to the hashlib
interface and use `new()` and `hexdigest()`.
## 0.2 (unreleased)
- This release was skipped.
## 0.1 (2011-05-18)
### Added
- Initial commit by James Cleveland.
