The first link is probably your best bet.

The GNU Crypto project has code for a bunch of different algorithms. Find more information here:

Good luck!

the reason I ask for a working algorithm is because I have seen this RFC you sent me, but I don't know how to put it together.  I copied the source from the RFC, but I can't make it compile.  What I'm looking for is a working 'compilable' version of HMCA-MD5... if you can help me put it together, it would be very helpful

Do you need the code in Java or in another language?

Strike that question (had a late night...)

If you're comfortable reading Java, the code that you can download from GNU would be right up your alley. The GNU libraries mentioned above are written in Java, and should be easy to translate into C++.
