= PGP Partitioned = PGP Partitioned is a format optionally used by Symantec in it's Endpoint security solution. It's not an official standard, it does not have a content type. There is just some mailing thread describing it. ([[http://www.ietf.org/mail-archive/web/openpgp/current/msg01811.html|partitioned]]) PGP Partitioned is basically a word for "PGP/Inline Mail Body and each attachment encrypted / signed separately " It can usually be identified by a "~P~G~Pexch.htm.pgp" Attachment containing the body of the mail as a ~H~T~M~L Page. Symantec's PGP Desktop can be configured to send PGP/MIME. This should be preferred. == Critique == * PGP Partitioned is not standardized in an RFC. * It does not properly handle encoding as it uses PGP/Inline. * Attachments and the Text are encrypted / signed as different PGP Messages. E.g. for a Signed and Encrypted Message with 10 Attachments a receiving MUA would have to show 10 different decryption and verification states. To do this securely and user friendly is nearly impossible. An attacker could add or remove attachments to a mail or change the encoding specified in the mail header making this format inherently insecure.
