GNU Miscfiles is a collection of common data files. They include, for example, country abbreviations, names and capital cities; currency abbreviations and names; a Best Current Practices index; a map of the ASCII character set; a list of three-letter airport codes; and an English word list.

This program is designed to make it easy to reconstruct difficult passwords when they are needed while limiting the risk of attack. The user of this program inputs a self-defined transformation of a web site URL and obtains the password and user name hint for that web site.

GnuCash is personal and professional financial-accounting software. It can be used to track bank accounts, stocks, income and expenses, based on the double-entry accounting practice. It includes support for QIF/OFX/HBCI import and transaction matching. It also automates several tasks, such as financial calculations or scheduled transactions.

To make the GnuCash documentation available, its doc output must be installed as well as Yelp, the Gnome help browser.

AqBanking is a modular and generic interface to online banking tasks, financial file formats (import/export) and bank/country/currency information. AqBanking uses backend plugins to actually perform the online tasks. HBCI, OFX DirectConnect, YellowNet, GeldKarte, and DTAUS discs are currently supported. AqBanking is used by GnuCash, KMyMoney, and QBankManager.

This package provides a helper library for networking and security applications and libraries. It is used by AqBanking.

This package provides Guile modules for connecting to various GNUnet services. It also has infrastructure for writing new GNUnet services and connecting to them and can be used from multi-threaded environments. It is not to be confused with guile-gnunet -- guile-gnunet supports a different set of services.

The following services are supported:

• NSE (network size estimation)

• DHT (distributed hash table)

• CADET (secure end-to-end communication between arbitrary peers)

GNUnet is a framework for secure peer-to-peer networking. The high-level goal is to provide a strong foundation of free software for a global, distributed network that provides security and privacy. GNUnet in that sense aims to replace the current internet protocol stack. Along with an application for secure publication of files, it has grown to include all kinds of basic applications for the foundation of a GNU internet.

For reliable NAT traversal, also install the miniupnpc package.

GNU libextractor is a library for extracting metadata from files. It supports a very large number of file formats, including audio files, document files, and archive files. Each file format is implemented as a plugin, so new formats can be added easily. The package also contains a command-line tool to extract metadata from a file and print the results.

GNU libmicrohttpd is a small, embeddable HTTP server implemented as a C library. It makes it easy to run an HTTP server as part of another application. The library is fully HTTP 1.1 compliant. It can listen on multiple ports, supports four different threading models, and supports IPv6. It also features security features such as basic and digest authentication and support for SSL3 and TLS.

This package provides a Pinentry implementation based on Bemenu.

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.

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.

Parcimonie incrementally refreshes a GnuPG keyring in a way that makes it hard to correlate the keyring content to an individual, and makes it hard to locate an individual based on an identifying subset of her keyring content. Parcimonie is a daemon that fetches one key at a time using the Tor network, waits a bit, changes the Tor circuit being used, and starts over.

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.

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.

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.

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

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

Paperkey extracts the secret bytes from an OpenPGP (GnuPG, PGP, etc) key for printing with paper and ink, which have amazingly long retention qualities. To reconstruct a secret key, you re-enter those bytes (whether by hand, OCR, QR code, or the like) and paperkey can use them to transform your existing public key into a secret key.

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

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).

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.
