Recommendations for RSA in C++

D'yer mind a code question? :) I'm looking at doing a security module and want to use RSA (but not PGP in general) for part of the protocol. I'd appreciate pointers to RSA implementations, preferably in C++ but C is ok. Free Source is a must. (I don't think RSAREF is freely reusable, is it?) TIA -- Roy M.
