You can sign or encrypt
email and PIN messages.
If you use a PGP Universal Server, your administrator might have set options so that the PGP Universal
Server always signs or encrypts your messages.
If you change the Certificate
field to None, you cannot read the message after you send it.
If you encrypt a message
and keys are not available for all recipients, you might be able to click Send to Server
to send the message to the PGP Universal
Server. If the PGP Universal
Server locates the keys, it encrypts the message. Otherwise, it might
send the message as plain text.
