GnuPG needs to construct a user ID to identify your key.

Real name: testuser
Email address: testuser@localhost
Comment: 
You selected this USER-ID:
    "testuser <testuser@localhost>"

Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? O
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.
