My bad, how about M2Crypto <http://sandbox.rulemaker.net/ngps/m2/> then? This one supports message digests and is more license compatible with Python to boot. [...]

This one does have md5 support, but the Python API is rather different from the current python md5sum API. It hooks into the slightly higher level MVP openssl layer, rather than the lower level md5 layer. Hooking into the MVP layer pretty much requires including all the openssl message digest implementations (which may or may not be a good idea).

It also uses SWIG to generate the extension module. I don't think anything else in Python itself uses SWIG, so starting to use it would introduce a "Build Dependency".

I think it would be cleaner and simpler to modify the existing md5module.c to use the openssl md5 layer API (this is just a search/replace to change the function names). The bigger problem is deciding what/how/whether to include the openssl md5 implementation sources so that win32 can use them.
