Are there any very simple RSA implementation in C++

Question

Are there any very simple cross-platform C++ libs which can do assymetric encription? Not necessary efficient, just working. I imagine it could be just 3-4 functions in an .h file which do arbitrary precission math and that's it.

I belive using OpenSSL here is an overkill.

http://cryptopp.com/ looks to be what I need. One might tear it down to individual files, and it has RSA samples.

+1 for crypto++. Often "simple" RSA implementations are lacking essential things, such as a secure padding. crypto++, as far as I can judge is carefully implemented and some versions of it have gone through NIST certification. – Accipitridae Aug 29 '10 at 10:10

@GregS: Yup. I noticed. Maybe you can regard this as a vote for Wei Dai's work. – Accipitridae Aug 29 '10 at 16:43
