How to add a comment to every encrypted email message when using PGP Partitioned Encoding.
Although this feature states the comment is added to "secured messages", older PGP Partitioned Encoding must be used for this comment to appear when using secure messaging. This feature does not work with the newer\current PGP/MIME encoding that is typically used by default. The reason this feature works only with PGP Partitioned encoding is when a message body is encrypted, the text itself is encrypted and the output is a block of cipher text. Such as the sample below:
-----BEGIN PGP MESSAGE-----
Version: PGP Desktop 10.2.0 (Build 2401)
Comment: This is the comment!
-----END PGP MESSAGE-----
PGP Partitioned encoding will also encrypt attachments individually and attach those to emails.
When PGP/MIME encoding is used, the entire message, including its attachments, are encoded into one single message.pgp file. When the recipient receives the encrypted content and automatically decrypts the message, there should no longer be a need to see any special comments. The message body is displayed automatically in the email and the attachments are placed properly as a regular attachment.
To add a comment to an unmanaged Symantec Encryption Desktop (previously PGP Desktop) encrypted email message using PGP Partitioned encoding:
To add a comment to a managed Symantec Encryption Desktop client encrypted email message using PGP Partitioned encoding:
Note: When enabled, the text you type here is always included in messages you encrypt or sign. Comments typed in this field appear below the --BEGIN PGP MESSAGE BLOCK-- text header and PGP Desktop version number of each secured message. These comments are not visible in decrypted emails.
Because this comment applies to cipher text Symantec Encryption Desktop creates, if using the "Current Window", or "Clipboard" functionality, this additional comment will also appear in this case.
For information on how to encrypt using the Current Window, or Clipboard functionality, please refer to HOWTO42131.
