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).

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.

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.

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.

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.

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 graphical interface for EFL that allows users to enter a passphrase when gpg is run and needs it.

This package provides a Pinentry implementation based on Bemenu.

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

QGpgme provides a very high level Qt API around GpgMEpp.

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.

Pinentry provides a console and a GTK+ 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.

QGpgME was originally developed as part of libkleo and incorporated into gpgpme starting with version 1.7.

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.

Npth is a library to provide the GNU Pth API and thus a non-preemptive threads implementation.

In contrast to GNU Pth is is based on the system's standard threads implementation. This allows the use of libraries which are not compatible to GNU Pth.

PyGPGME is a Python module that lets you sign, verify, encrypt and decrypt messages using the OpenPGP format by making use of GPGME.

Jetring is a collection of tools that allow for gpg keyrings to be maintained using changesets. It was developed with the Debian keyring in mind, and aims to solve the problem that a gpg keyring is a binary blob that's hard for multiple people to collaboratively edit.

With jetring, changesets can be submitted, reviewed to see exactly what they will do, applied, and used to build a keyring. The origin of every change made to the keyring is available for auditing, and gpg signatures can be used for integrity guarantees.

WMND is a dockapp for monitoring network interfaces under WindowMaker and other compatible window managers.

Wmbattery displays the status of your laptop's battery in a small icon. This includes if it is plugged in, if the battery is charging, how many minutes of battery life remain, battery life remaining (with both a percentage and a graph), and battery status (high - green, low - yellow, or critical - red).

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.

Libobjc2 is an Objective-C runtime library designed as a drop-in replacement for GCC runtime. It supports following features beyond GCC runtime.

• Modern Objective-C runtime APIs.

• Blocks (Closures).

• Synthesised property accessors.

• Efficient support for @synchronized().

• Type-dependent dispatch.

• Associated reference API.

• Automatic Reference Counting.

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.

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.
