Encryption Question

Encrypting an E-mail...

[omoutop]

Hi to all!

in one of my scripts I have abooking form which is sent by e-mail to the user (php mail function)...what I want is to encrypt the e-mail (contents) while providing users with specific keys in order to unencrypt the e-mail afterwards...I know that encryption methods such as password, md5 etc.. cannot be a solution since encrypted strings cannot be retrieved...is there any other way to create such system?
Thank you

Generally something like PGP/GPG is used. Since it uses public key encryption, the server only needs the public key and the messages can't be read if the server is comprimised. The user receiving the message has the secret key.
