First is that there is more to having a secure email conversation than using a public/private key encryption.
What? I didn't understand what you tried to say...
The second is that the key pair has a mathematical relationship that I cannot replace the private key since it would violate the relationship and not work.
Yes. There is only one public key to a private key. If you have the public key from someone, you can not obtain the private key, and vice-versa. Cipher text = (Clean text ^ private key) modulum n, n is obtained by calculus above two big(gigant) prime numbers and Euler functions... To decript, Clean Text = (Cipher text^public key) modulum n. bye, Daniel Menezes Daniel Pordeus Menezes Analista de Sistemas Petrobras - cp37 -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f Sponsor: Alimentazione biologica, fanghi di Guam, aloe vera, prodotti di bellezza Erbolario.
