Step 3: Generate Some Keys
Then, I ran the app and it had me generate my two keys (one public, one private). I typed in my secret passphrases which, of course, I will never tell anyone.
The last step with my keys was to select my public key and export it to a text file. Once you do this, you can attach it or copy and paste the contents into an e-mail to send to you PGP/GPG wielding friends.
