GnuPG::Interface and its associated modules are designed to provide an object-oriented method for interacting with GnuPG, being able to perform functions such as but not limited to encrypting, signing, decryption, verification, and key-listing parsing.

GPA, the GNU Privacy Assistant, is a graphical user interface for GnuPG. It can be used to encrypt, decrypt, and sign files, to verify signatures, and to manage the private and public keys.

Signing-party is a collection for all kinds of PGP/GnuPG related things, including tools for signing keys, keyring analysis, and party preparation.

1. caff: CA - Fire and Forget signs and mails a key

2. pgp-clean: removes all non-self signatures from key

3. pgp-fixkey: removes broken packets from keys

4. gpg-mailkeys: simply mail out a signed key to its owner

5. gpg-key2ps: generate PostScript file with fingerprint paper strips

6. gpgdir: recursive directory encryption tool

7. gpglist: show who signed which of your UIDs

8. gpgsigs: annotates list of GnuPG keys with already done signatures

9. gpgparticipants: create list of party participants for the organiser

10. gpgwrap: a passphrase wrapper

11. keyanalyze: minimum signing distance (MSD) analysis on keyrings

12. keylookup: ncurses wrapper around gpg --search

13. sig2dot: converts a list of GnuPG signatures to a .dot file

14. springgraph: creates a graph from a .dot file

Libassuan is a small library implementing the so-called Assuan protocol. This protocol is used for IPC between most newer GnuPG components. Both, server and client side functions are provided.

Pinentry-rofi is a simple graphical user interface for passphrase or PIN when required by gpg or other software. It is using the Rofi application launcher as the user interface. Which makes it combined with rofi-pass a good front end for password-store.

Pinentry provides a console and a Qt GUI that allows users to enter a passphrase when gpg is run and needs it.

QGpgme provides a very high level Qt API around GpgMEpp.

Libgcrypt is a general-purpose cryptographic library. It provides the standard cryptographic building blocks such as symmetric ciphers, hash algorithms, public key algorithms, large integer functions and random number generation.

Pinentry provides a console and a GTK+ GUI that allows users to enter a passphrase when gpg is run and needs it.

The GNU Privacy Guard is a complete implementation of the OpenPGP standard. It is used to encrypt and sign data and communication. It features powerful key management and the ability to access public key servers. It includes several libraries: libassuan (IPC between GnuPG components), libgpg-error (centralized GnuPG error values), and libskba (working with X.509 certificates and CMS data).

This package provides Python bindings to the GPGME GnuPG cryptographic library. It is developed in the GPGME source code, and then distributed separately.

pgpdump displays the sequence of OpenPGP or PGP version 2 packets from a file.

The output of this command is similar to GnuPG's list packets command, however, pgpdump produces more detailed and easier to understand output.

Libgpg-error is a small library that defines common error values for all GnuPG components. Among these are GPG, GPGSM, GPGME, GPG-Agent, libgcrypt, Libksba, DirMngr, Pinentry, SmartCard Daemon and possibly more in the future.

GnuPG Made Easy (GPGME) is a library designed to make access to GnuPG easier for applications. It provides a High-Level Crypto API for encryption, decryption, signing, signature verification and key management. Currently it uses GnuPG as its backend but the API isn't restricted to this engine.

Because the direct use of GnuPG from an application can be a complicated programming task, it is suggested that all software should try to use GPGME instead. This way bug fixes or improvements can be done at a central place and every application benefits from this.

Pinentry provides a console and an Emacs interface that allows users to enter a passphrase when required by gpg or other software.

Guile-Gcrypt provides a Guile interface to a subset of the GNU Libgcrypt crytographic library. It provides modules for cryptographic hash functions, message authentication codes (MAC), public-key cryptography, strong randomness, and more. It is implemented using the foreign function interface (FFI) of Guile.

This module allows easy access to GnuPG’s key management, encryption and signature functionality from Python programs.

Pinentry provides a console and a GTK+ GUI that allows users to enter a passphrase when gpg is run and needs it.

KSBA (pronounced Kasbah) is a library to make X.509 certificates as well as the CMS easily accessible by other applications. Both specifications are building blocks of S/MIME and TLS.

Window Maker is an X11 window manager originally designed to provide integration support for the GNUstep Desktop Environment. In every way possible, it reproduces the elegant look and feel of the NeXTSTEP user interface. It is fast, feature rich, easy to configure, and easy to use.

The makefile package is a simple, powerful and extensible way to write makefiles for a GNUstep-based project. It allows the user to write a project without having to deal with the complex issues associated with configuration, building, installation, and packaging. It also allows the user to easily create cross-compiled binaries.

wmamixer is an applet for window maker which displays the current volume level both numerically and visiaully with a volume bar. It includes the ability to toggle through different outputs to show their respective volume level.

Wmcpuload displays the current CPU usage, expressed as a percentile and a chart, and has an LCD look-alike user interface. The back-light may be turned on and off by clicking the mouse button over the application. If the CPU usage hits a certain threshold, an alarm-mode will alert you by turning back-light on.

wmclock is an applet for Window Maker which displays the date and time in a dockable tile. It features multiple language support, 24h or 12h time display, and can run a user-specified program on mouse click.
