From main menu, choose "Privacy > Generate Keypair" to enter this screen. Once entered, you will be presented with a form to enter necessary data to generate a keypair for yourself:
Enter your name here; if you later order a per-user license, you will need to provide the exact name like this
Enter your e-mail address here; this is part of your key information to communicate with others
Describe yourself over here; for your personal use, "Private Citizen" is a very good choice; for your professional use, your profession such as "Software Engineer" should be a good choice too
Enter your passphrase here; passphrase has some similarity with widely used password but with enhanced security; passphrase can be very long; a passphrase often consists of a sequence of words; please read this topic on wikipedia.org for more information
Re-enter passphrase to make sure you did not mistype your passphrase
Once the form is filled out, click
button on the toolbar to continue.
It will take a while to generate your keypair and a moving progress bar
will be shown until it is done.
Once the keypair is generated, it is recommended to restart the application. You will see the "Generate Keypair" menu item being dimmed to prevent you from creating another keypair for yourself.
