Edit Question
Title
Body
I'm looking for two functions conceptually similar to these: // returns the encrypted text string encrypt( string public_key, string pass_phrase, string text ); // returns the original text string decrypt( string private_key, string pass_phrase, string encrypted_text ); where string could be a char* , a std::string or something easily convertible to those two. And where public_key and private_key can be basically anything, from keys generated with some commands (gpg/ssl stuff or whatever), to keys generated with other simple functions. I've looked into a few cryptography libraries (libgcrypt, libgpgme, openssl ...), but it doesn't look easy at all to implement such functions with those libraries: they require a non-superficial knowledge about asymmetric encryption and a lot of code. Anyway this task doesn't seem uncommon. How can I implement the two functions above?
