This is crypt fork, add etcdv3 support.

crypt

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

• crypt cli
• crypt/config

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.
