Podczas tworzenia klucza zostaniemy poproszeni o kilka odpowiedzi. Początkowe dotyczą typu i siły klucza. Używamy wartości domyślnych. Następnie pytani jesteśmy o nazwisko i imię, adres email oraz komentarz. Musimy też podać hasło jakim będzie zabezpieczony nasz klucz prywatny. Następnie czekamy i wciskamy co popadnie żeby komputer mógł wylosować odpowiednio dużo liczb losowych.

Przykład utworzenia pary kluczy:

gpg --gen-key

A oto wyniki komendy i przykład dodadkowych pytań zadawanych w trakcie wykonania. Proces wymaga bardzo dużej ilości liczb losowych tak ze może zatrzymać się w połowie i poprosić o rzuszanie myszą lub wciskanie klawiszy by wygenerować dodatkowe liczby losowe.

You need a Passphrase to protect your secret key.
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.

Not enough random bytes available. Please do some other work to give the OS a chance to 
collect more entropy! (Need 255 more bytes)We need to generate a lot of random bytes.

W taki sposób wygenerowaliśmy klucze potrzebne do podpisów i szyfrowania.
