I checked that the openssl library does have a call for this, however, I cannot 
see this exposed in either the cryptography or py2crypto packages. The code may 
be in there, but I don't see it obviously exposed. I think m2crypto might do the 
job, but building it for windows is a pain and I probably have to build it 6 
times ie 32 & 64 bits x 2.7 3.3 & 3.4. There are pre-built versions of openssl, 
but that's also a moving target right now.
