Python wrapper for bcrypt
Bcrypt is an implementation of a modern password hashing algorithm, based on the Blowfish block cipher, by Niels Provos and David Mazieres. It has been the default password scheme since OpenBSD 2.1.
- A paper on the algorithm that explains its design decisions is available here:
The most important property of bcrypt is that it is adaptable to future processor performance improvements, allowing you to arbitrarily increase the processing cost of checking a password while still maintaining compatibility with your older password hashes.
This package provides a high level object oriented wrapper around bcrypt, as well as low level bindings to the C library. It uses the random number generator random.SystemRandom() to create the salts.
To build the module from source code, read documentation on doc/source.txt.
Yamlog manages the error catching code and error reporting. Read its documentation if want to be set up.
import bcryptor hasher = bcryptor.Bcrypt() hash = hasher.create('crack my pass')
And to validate:
>>> hasher.valid('crack my pass', hash) True >>> hasher.valid('Crack my pass', hash) False
- Fixed an import error at loading the package to get its docstring. It doesn’t works when is imported a module generated by cython which has not built.
- Added a null handler to logging, since Yamlog could not has been set up.
- The license has been changed to ISC.
- For indentation, is used 4 spaces as is indicated in PEP-8.
- The manage of exceptions and imports has been improved.
- Better docstrings.
- The values of cost can be changed at instancing Bcrypt().
- Changed from Pyrex to Cython.
- The logging is managed through Yamlog.
- Initial release.
