Using PGP
Before you can begin using PGP, you need to generate a key pair. A PGP key

key that you can copy andmake freely available to everyone with whom you
exchange information.

window:
1. Choose New Key from the Keys menu.
2. The PGP Key G eneration Wizard asks you to enter your name and email
address. You do not have to enter your real name or even your email
address. Ho wever, using your real name makes it easier for ot hers t o
identify yo u as t he o wner of your public key.
3. Click Next; then select a key type.
4. Select a key size, or enter a custom key size from 768 to 4096.
5. Choose w hen the key pair expires (enter a specific d ate or accept the
