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.

The GNU Coding Standards were written by Richard Stallman and other GNU Project volunteers. Their purpose is to make the GNU system clean, consistent, and easy to install.

The information for maintainers of GNU software has guidelines and advice for someone who is the maintainer of a GNU program on behalf of the GNU Project.

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.

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

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.

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.

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 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 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)

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.

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 that allows users to enter a passphrase when gpg is run and needs it.

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.

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.

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).

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.

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.

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.

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

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.

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