Hello, Maybe, in my last post, I didn't explain my problem as well...
I'm trying to identify the functions to integrate in my client-server application (developped in C/C++ language) that allow me to construct an assimetric encryption system. Specifically, I need to know the functions for 1) Generating (& identificating) both private & public keys. 2) Signing the public key with the foreign private key. 3) Encrypting messages using the foreign public key. 4) Decrypting messages using the private key. I need help to be pointed at the documentation pages & the concrete functions. Moreover, I read that RSA is so good... Could you help me ? S.
