crypt
You can use crypt as a command line tool or as a configuration library:
Demo
Watch Kelsey explain crypt in this quick 5 minute video:
Generating gpg keys and keyrings
The crypt cli and config package require gpg keyrings.
Create a key and keyring from a batch file
vim app.batch
%echo Generating a configuration OpenPGP key
Key-Type: default
Subkey-Type: default
Name-Real: app
Name-Comment: app configuration key
Name-Email: app@example.com
Expire-Date: 0
%pubring .pubring.gpg
%secring .secring.gpg
%commit
%echo 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.
