1.3 Overview

This protocol enables the client to create and consume rights-managed email messages by defining a format for creating and writing an email message with encrypted and compressed content.

When a client creates a rights-managed email message, it encrypts and compresses the contents of the message (body, attachments, and so on) and stores the encrypted, compressed contents as part of the message that is sent to the recipients. The client sets certain properties on the message to identify it as rights-managed.

When a client receives a rights-managed email message, it decompresses and decrypts the encrypted binary large object (BLOB) and displays the content to the end user if the end user has sufficient permission to view the content. In addition, the client disables certain functionality on the rights-managed email message to prevent the recipient from using the message content in an unauthorized manner.
