Cryptography #2

So, it turns out I couldn’t generate public keys from private ones using Diffie-Hellman algorithm, it took several minutes for even a limited size private key.

In the end I went back to visual basic and after lots of researching(thanks stackoverflow) I got a handle on how to extract(export) private and public keys.
That may be unnecessary though, I can simply send a signature with the algorithm I’m using(one called “ECDsa”). If I were to save the private key I’d need to authorize it at object(Security.Cryptography.CngKey) instantiation.

I need to send the public key even if I have a signature. No idea why I said I didn’t need to. I spent most of the previous days trying to accomplish just that.
