<p>The present disclosure provides a system and method for end-to-end electronic mail encryption. In one embodiment, the sender contacts a payload-encryption-packet creation server which receives the message the sender would like to encrypt, generates an encrypted message and a payload-encryption-packet, and returns both to the sender. The sender then uses his regular email infrastructure to transmit to the recipient the encrypted message and the payload-encryption-packet as a single email. Upon receiving the sender's email, the recipient contacts a payload-encryption-packet processing server and sends it the payload-encryption-packet and authorization information. Depending on the validity of the authorization information, said server processes the payload-encryption-packet and provides the recipient with information usable for extracting the original message from the encrypted message.</p> |
