pysha2 is a pure Python implementation of the FIPS 180-2 secure hash
standard. I originally wrote and published this on the web prior to
the inclusion of hashlib into the Python standard
library. Unfortunately, the original source was lost due to a hard
drive failure. Fortunately, the library proved useful to some at the
time (due to the prevalence of Python 2.3 and 2.4), and so I was able
to recover all but the unit tests (which I later rewrote).
The library supports both the "old" hash interface of md5 and
sha, as well as the "new" hash interface introduced by
hashlib. This permits you to use pysha2 as a drop-in replacement
for either interface.
A quick example of hashing a string:
import sha2
print sha2.sha256('Can you keep a secret?').hexdigest()
To run the included unit tests, execute:
python test.py
in the current directory or run with nosetests.
