Hi you may want to check out BouncyCastle at http://en.wikipedia.org/wiki/Bouncy_Castle_%28cryptography%29.

Most are in Java and C# but I believe there maybe some implementation in C or C++.

If you cannot find, since it is Open Source, you can "convert" those Java, C# code into their C/C++ equivalent. A major under-taking I guess but who knows you can spawn off a C/C++ BoucyCastle or join forces with them to produce crypto API for C/C++.

Don't know any library for C, but there is Crypto++ for C++.

Read the licensing section. I don't really get it though.
