Specifications

Options within this program include help, which will describe the available commands—
trust, sign, and save.
Type trust and tell GPG that you trust your key fully. Type sign to sign this public key using
nobody’s private key. Finally, type save to exit this program, keeping your changes.
Testing GPG
GPG should now be set up and ready to use.
Creating a file containing some text and saving it as test.txt will allow us to test it.
Typing the following command
gpg -a --recipient ‘Luke Welling <[e-mail]>’ --encrypt test.txt
(modified to use the name of your key) should give you the warning
gpg: Warning: using insecure memory!
and create a file named test.txt.asc. If you open test.txt.asc you should see an encrypted
message like this:
