Is there a very simple RSA implementation in C ++

Question

Are there any very simple cross-platform C ++ libraries that can perform asymmetric subscription? No need effective, just working. I assume that it can be just 3-4 functions in the .h file that perform arbitrary math finishing and that it is.

I believe that using OpenSSL is redundant here.

Answer 1

http://cryptopp.com/ looks like what I need. One could tear it into separate files, and it has RSA samples.
