Currently the PGP support in PBM is limited to PGP 2.6.x (RFC 1991) If you have a PGP keyring that was created by anything other than PGP 2.6.x you will have to download PGP 2.6.x and create a new one.

Settings
To setup PGP go to the Settings
dialog and select the PGP panel. Enter the paths to the keyrings, the public
keyring is PUBRING.PGP, the secret keyring is SECRING.PGP. You must
enter the full path to those files. You can also use the Find Public Keyring
and Find Secret Keyring buttons which will bring up a File dialog and allow you to
navigate to the files.
After you have filled in the keyrings, use the Find ID button
and select your ID from the list. If you would like your
passphrase stored in the settings, enter it here and use the Test Passphrase
button to make sure you typed it correctly. If you choose not to enter it here,
you will be prompted for it when Polarbar attempts the first retrieval
and if you are worried about leaving your passphrase in memory, you can clear it by selecting
Tools->PGP->Clear PGP Passphrase
Encrypting
You can PGP encrypt a message to multiple
people. Press the + button and select the names from your public
keyring. If you made a mistake, you can remove them by selecting them
in the drop down box and pressing -. After you have typed the portion
of your message that you would like be encrypt, press the Encrypt button.
Signing
To sign an email, bring up the Persona dialog and check the "PGP Sign Email"
checkbox at the bottom. The PGP signing can take a few seconds so don't worry if
you press send and the compose dialog doesn't disappear right away.
Once the passphrase has been entered, any email received will be automatically verified. If the message is PGP signed you will see the text of the message begin with -----BEGIN PGP SIGNED MESSAGE-----. If the user's public key is on your keyring and the message was verified, a green padlock will appear in the PGP icon column. If it fails verification the padlock will have a red X through it. If the message was signed but the user is not on your keyring, no PGP icons will appear in the PGP icon column.
Decrypting
To decrypt an email, simply RMB on the message
and select PGP->Decrypt PGP message. The existing text in the window
will disappear and the decrypted text will be shown. If you change to another
message and then change back, you will see the encrypted text and you will need
to decrypt it again.
Viewing users
To see the users on your public
keyring from the menu go to Tools->PGP->View Public PGP IDs
Adding users
If someone has sent you their ascii keyblock, you can add them to your
keyring by pressing RMB in the message window and selecting
PGP->Add PGP keyblock to public keyring. PBM can also search the
MIT keyserver if you select
RMB->PGP->Get FROM addr public key from keyserver and add it
After you add someone's public key, you can manually verify their email by
RMB->PGP->Verify PGP signature in message.
Distributing your public key
To distribute your public key to others you can either put a keyblock into
your sig or go to the
MIT keyserver and add it there. To put the keyblock
in your sig you must go back to the PGP program again and type
pgp -kxa yourID outfile In the example above the command would look like
pgp -kxa jpolar@myisp.com keyblock.asc In PBM you can create a persona and
cut and past the contents of the keyblock.asc file into your signature.
