MD5 Hash Generation

I did a search for how to generate MD5 hash's through C++ or even C, but I was unable to find a answer as to how this is done. It appears that there isn't a standard function for MD5 in C or C++, unless I missed it, so I was hopeing there was a class out there or something. Does anyone know anything that will help me out here? Thanks.

No standard implementation (as far as I know)
