Performing PGP functions from the clipboard
You will notice that many of the options on the System tray refer to PGP
functions that you perform from the Windows clipboard. If you are using an
email application that is not supported by the PGP plug-ins, or if you are
working with text generated by some other application, you perform your
encryption/decryption and signature/verification functions via the Windows
clipboard.

email application that is not supported by the PGP plug-ins, or if you are
working with text generated by some other application, you perform your
encryption/decryption and signature/verification functions via the Windows
clipboard.
For instance, to encrypt or sign text, you copy it from your application to the
clipboard, encrypt and sign it using the appropriate PGP functions, then paste
it back into your application before sending it to the intended recipients. When
you receive an encrypted or signed email message, you simply reverse the
process and copy the encrypted text, known as ciphertext from your
application to the clipboard, decrypt and verify the information, and then
view the contents. After you view the decrypted message, you can decide
whether to save the information or retain it in its encrypted form.

yourself as well as any public keys of other users that you have added to your
public keyring. (If you have not already created a new key pair, the PGP Key
Generation Wizard leads you through the necessary steps. From the PGPkeys
window you can create new key pairs and manage all of your other keys. For
instance, this is where you examine the attributes associated with a particular
key, specify how confident you are that the key actually belongs to the alleged
owner, and indicate how well you trust the owner of the key to vouch for the
authenticity of other users’ keys.
