gpgkeys 1.23

A GnuPG Shell

Package Documentation

Introduction

gpgkeys is a Python program that allows to conveniently manage GnuPG keys and keyrings from the command line. It comes in the form of a shell, with commands resembling GnuPG CLI commands and their options. Its main feature is end-to-end tab completion.

gpgkeys also serves as testbed for the development of the kmd and rl Python libraries.

Motivation

The GnuPG CLI is very powerful – and with great power comes great incomprehensibility.

gpgkeys makes key management easy by:

  1. Providing a sensible subset of GnuPG commands, and
  2. Using tab completion to streamline the input process and guide the user through key management tasks.

Example Session

Everything in gpgkeys can be tab completed: commands, help topics, option flags, key ids, user names, file names, shell commands, and keyserver URLs.

$ gpgkeys
gpgkeys 1.23 (type help for help)

gpgkeys> help

Available commands (type help <topic>):
=======================================
EOF       del   export  genkey     import   lsign  refresh  shell
checksig  dump  fdump   genrevoke  list     quit   search   sign
clear     edit  fetch   help       listsig  recv   send     version

Shortcut commands (type help <topic>):
======================================
!  .  ?  e  ll  ls

gpgkeys> help export
Usage: export <keyspec>
Options: --armor --clean --minimal --output --secret

Export keys to stdout or to a file

gpgkeys> ls Stefan
pub   1024R/E1F438AD 1995-10-03
uid                  Stefan H. Holek (RSA) <stefan@epy.co.at>

pub   1024D/355A2D28 2001-11-04
uid                  Stefan H. Holek <stefan@epy.co.at>
sub   2048g/A27E0DBC 2004-10-27

gpgkeys> export --armor 355A2D28 > stefan.asc
gpgkeys> .ls
alice.asc             stefan.asc

Features

Command lines prefixed with '.' or '!' are executed by the shell. You can use cd to change the current directory, umask to change the umask, and of course everything else:

gpgkeys> .cd subdir/
gpgkeys> .pwd
/home/stefan/subdir

You can use input/output redirects and pipes:

gpgkeys> export 355A2D28 | pgpdump | less

To see the commands sent to GnuPG, run gpgkeys with the -v option:

$ gpgkeys -v
gpgkeys 1.23 (type help for help)

gpgkeys> ls 355A2D28
gpgkeys: gpg --list-keys 355A2D28
pub   1024D/355A2D28 2001-11-04
uid                  Stefan H. Holek <stefan@epy.co.at>
sub   2048g/A27E0DBC 2004-10-27

For everything you ever wanted to know about GnuPG commands, type:

gpgkeys> .man gpg

gpgkeys can be invoked with arguments, in which case it does not enter the command loop:

$ gpgkeys export --armor 355A2D28 > stefan.asc

Keyservers

For the send, recv, search, and refresh commands to work, at least one keyserver should be configured in gpg.conf. For example:

keyserver ldap://keyserver.pgp.com
keyserver hkp://pool.sks-keyservers.net

The last keyserver in gpg.conf becomes the default keyserver. All keyservers become available for completion after the --keyserver option.

Unicode

OpenPGP allows user IDs to be either Latin-1 or UTF-8 encoded. To find keys with non-ASCII IDs, GnuPG requires search strings to be encoded the right way.

gpgkeys' key completion keeps track of the original encodings, and every name you tab-complete will automatically be encoded the way GnuPG expects. You may sometimes see '?' characters in place of non-ASCII characters on the command line, which are a result of the above and no reason for concern.

Development

gpgkeys development is hosted on GitHub. It also has an issue tracker there.

Installation

Installation requires Python 2.5 or higher, including Python 3.3.

gpgkeys depends on kmd, which in turn uses the rl library. Since rl contains a C extension, it is a good idea to review its installation instructions and make sure all dependencies are in place.

To install the gpgkeys script, type:

easy_install gpgkeys

Then put it on your system PATH by e.g. symlinking it to /usr/local/bin.

Requirements

The gpg command must be available on the system PATH.
