Encrypting a message for a friend
The first thing you'll need is to get your friends public pgp key. Save it as a text file.
Click on 'Import' select the text file where you saved your friends public pgp key.
For this example we'll use the public PGP key from our friends at anarsec.guide.
Click 'Import'
