regpg - safely store server secrets

The 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.



If you use regpg, let me know! Send me mail at

If you would like to submit a bug report or a patch, or if you would like more information about regpg's licence, see doc/


For a simple one-file install you can copy the regpg script to a directory on your $PATH.

You can run make install to install the script and man page to the standard places in your home directory, and make uninstall to remove them. See the start of the Makefile for variables you can set on the command line to adjust the install location. See doc/ for details about building from git.


To use regpg you need the following programs. I've listed the versions that I have tested.

You only need the following programs if you use regpg's helper subcommands.

You only need the following to build from git.


Download the single-file regpg perl script: and its GPG signature.

Thanks to Jon Warbrick who gave me the idea for regpg's key management; and David Carter, Ben Harris, Ian Lewis, David McBride, mchubby, and Matthew Vernon for helpful bug reports and discussions.
