Generating a GPG key
gpg --full-generate-key
gpg --list-secret-keys --keyid-format=long
From the list of GPG keys, copy the long form of the GPG key ID you’d like to use. In this example, the GPG key ID is 3AA5C34371567BD2:
$ gpg --list-secret-keys --keyid-format=long /Users/hubot/.gnupg/secring.gpg ------------------------------------ sec 4096R/3AA5C34371567BD2 2016-03-10 [expires: 2017-03-10] uid Hubot ssb 4096R/42B317FD4BA89E7A 2016-03-10
gpg --armor --export 3AA5C34371567BD2 # Prints the GPG key ID, in ASCII armor format
Copy your GPG key, beginning with -----BEGIN PGP PUBLIC KEY BLOCK----- and ending with -----END PGP PUBLIC KEY BLOCK-----.
