You can use crypt as a command line tool or as a configuration library:

• crypt cli
• crypt/config

Watch Kelsey explain crypt in this quick 5 minute video:

The crypt cli and config package require gpg keyrings.

vim app.batch

�ho Generating a configuration OpenPGP key
Key-Type: default
Subkey-Type: default
Name-Real: app
Name-Comment: app configuration key
Name-Email: [email protected]
Expire-Date: 0
%pubring .pubring.gpg
%secring .secring.gpg
%commit
�ho done

Run the following command:

gpg2 --batch --armor --gen-key app.batch

You should now have two keyrings, .pubring.gpg which contains the public keys, and .secring.gpg which contains the private keys.

Note the private key is not protected by a passphrase.
