I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

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?
Tommy BraasCommented:
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++.
