Known Bugs

Messages saved decrypted in Outlook

If the Automatically decrypt/verify when opening messages checkbox under the Email tab in PGP Options is checked, encrypted messages can silently be saved unencrypted in M$ Outlook. This occurs for example when replying to an encrypted message.

To avoid the bug, you have to do one of the following:

Switch off the Automatically decrypt/verify when opening messages option (see Setting PGP Options). Decryption will now require a click on a decrypt icon in Outlooks toolbar.
Pay USD 50 for the latest non-freeware version of PGP (sold by Phil Zimmermann). Since the software uses an "activation scheme", you will might end up having to buy a new license each time you upgrade your computer (change disks, expand memory etc or even recover from a crash), so this could be money unwisely spent.
Assemble your own solution from bits and pieces found at Alternative Software. Interesting and commendable stuff, alas not for the lazy.

The Klima/Rosa vulnerability

The Klima/Rosa attack, named after those who discovered the security hole, can be used to snatch your signing key (signing is not covered by this guide). However, your decryption key is perfectly safe. For details about the vulnerability, see  Key Vulnerability on Tom McCune's PGP page. Note that the attacker needs read and write access to your files in order to succeed. If that is the case, you're likely to have big security problems.
