regpg program is a thin wrapper around
gpg for looking after
secrets that need to be stored encrypted in a version control system
(so you don't have to trust the VCS server) and decrypted when your
configuration management system deploys them to servers.
discreet and discrete
regpg is designed to store each secret in its own
ASCII-armored PGP-encryped file, separate from non-secret
code and configuration. The only other file
is a public keyring.
simplified key management
regpg manages a keyring containing the public keys of
whoever is allowed to decrypt the secrets.
There is no need to curate your personal public keyring, or
get involved in the web of trust, or use PGP keyservers.
You exchange public keys with your colleagues via the
pubring.gpg file in your version control system.
After you have added or removed a key it is easy to re-encrypt
regpg can check that all secrets are properly
encrypted to the keys in its
regpg has subcommands for generating and encrypting TLS and
SSH private keys in one step, and for wrangling X.509
There are also some quick
init commands to get
regpg hooked up
git, and some
conv commands to help you
regpg from other tools.
conventional project layout
At the root of your project you have a
pubring.gpg file which
lists the set of people who can decrypt the secrets. This is your
current working directory when using
regpg. Elsewhere in your
project directory and its subdirectories you have encrypted
secret.asc files. The F<.asc> extension is short for
ASCII-armored PGP message.
regpg help displays the reference manual, or you can read it at
an introduction and overview of
regpg's approach to handling secrets.
