I think I understand the answer to my question... First is that there is more to having a secure email conversation than using a public/private key encryption. 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. Thanks to everyone answering my question.

For this reason you can't make an arbitrary pair and say they are a key set. --------------------------------------------------------------------------- Free 30-day trial: firewall with virus/spam protection, URL filtering, VPN, wireless security Protect your network against hackers, viruses, spam and other risks with Astaro Security Linux, the comprehensive security solution that combines six applications in one software solution for ease of use and lower total cost of ownership.
