Discretion™ by Hallberg Ulrich

If you are tired of the way that PGP Mail's "Encrypt new messages by default" feature continually leads to pop-up dialogs for missing keys, then Discretion is the remedy.

How It Works

Discretion integrates into Microsoft Outlook in the same way as PGP Mail. It provides the following features to automate the selection of encryption and signing for outgoing mail:

• "Encrypt messages if all recipients are found in PGP's default keyring" (a substitute for PGP Mail's "Encrypt new messages by default").
• "Sign messages if all recipients are found in PGP's default keyring" (a substitute for PGP Mail's "Sign new messages by default").

Discretion uses PGP's publicly available programming interface to search for message recipients in your default PGP keyring. When Discretion selects encryption or signing, the appropriate PGP toolbar button is pressed down, just as if you had made the same selection manually.

Note that Discretion's operation is strictly one-way: it will never deselect encryption or signing for any message.
