METHODS AND APPARATUS FOR ENCRYPTING AND DECRYPTING EMAIL MESSAGES

摘要

An e-mail encryption method the sender embeds commands and optionally, parameters relating to the commands in an e-mail message. A domain suffix associated with an encryption e-mail server is appended to the recipient e-mail address before sending the e-mail message. The e-mail message is sent and delivered to the encryption e-mail server. The encryption e-mail server parses the e-mail message and executes any commands, optionally executing the commands based on submitted parameters. The encryption e-mail server encrypts the message and forwards the encryption message, or alternatively, a link to a memory location in the encryption email server where the encryption e-mail message is stored. The recipient receives an email notifying them of the encrypted message. The recipient is prompted for a password. The password is validated. If valid and no limits on the e-mail are exceeded, the contents of the encrypted e-mail message are decrypted and displayed for the recipient.
