Any DLL's that handle Public Key Encryption or Key Exchange?

I'm in the process of writing a freeware IRC client in Visual Basic 3 and wanted to encorporate a secure variant of DCC chat. Trouble is I can't find a precompiled library that has either RSA or DH in it. This doesn't do me much good as I don't even own a Windows C compiler... (is that a crime in some countries? :) ) I'll appreciate any help you folks could give.. Greg Morgan Vice President: Crescent Moon Productions draven@infi.net PGP Public Key via E-Mail
