The next option asks you to specify how long you want your key to be valid. If you do choose an

expiration date, remember that anyone who is using your public key must also be informed of its

expiration and supplied with a new public key. It is recommended that you select no expiration date. If

you do not choose an expiration date, you are asked to confirm your decision:

Key does not expire at all Is this correct (y/n)?

Press y to confirm your decision.

Your next task is to provide a User-ID containing your name, your email address, and an optional

comment. Each is requested individually. When you are finished, you are presented with a summary of

the information you entered.

Once you accept your choices, you enter a passphrase.

Tip

Like your account passwords, a good passphrase is essential for optimal security in GnuPG. Mix

your passphrase with uppercase and lowercase letters, use numbers, and/or include punctuation

marks.

Once you enter and verify your passphrase, your keys are generated. A message similar to the

following appears:

We need to generate a lot of random bytes. It is a good idea to perform some

other action (type on the keyboard, move the mouse, utilize the disks)

during the prime generation; this gives the random number generator a

better chance to gain enough entropy.

When the activity on the screen ceases, your new keys are placed in the directory .gnupg in root's

home directory. This location is because you are ran the command as root. To list your root keys, use

the command:

gpg --list-keys

The output is similar to the following:

/root/.gnupg/pubring.gpg ---------------- pub 1024D/B7085C8A 2002-02-18

sub 1024g/E12AF9C4 2002-02-18

To retrieve your public key, use the following command:

gpg --export -a 'Your Name' > public_key.txt

Your public key is written to the file public_key.txt.
