-My motivation to write this code was the lack of a nicely licensed
-hmac_md5 function in C. I programmed it following the RFC's text.
-Obviously this code is highly similar to the sample code of the RFC.
-The code is tested against the test vectors of the RFC. Wikipedia's
-HMAC page helped me to understand the algorithm better.

-This hmac_md5 function requires an OpenSSL-compatible MD5
-implementation. There are Public Domain MD5 implementations by Colin
-Plumb and by Solar Designer. You probably want to use one of these.
