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

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.

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.

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 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.

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.

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.

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

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

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.

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

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.

Pius (PGP Individual UID Signer) helps attendees of PGP key signing parties. It is the main utility and makes it possible to quickly and easily sign each UID on a set of PGP keys. It is designed to take the pain out of the sign-all-the-keys part of PGP key signing parties while adding security to the process. The pius-keyring-mgr and pius-party-worksheet commands help organizers of PGP key signing parties.

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.

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

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

This package provides a Pinentry implementation based on Bemenu.

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 provides a console and a GUI designed for use with GNOME 3 that allows users to enter a passphrase when required by gpg or other software.

This package provides a very simple Pinentry implementation based on Fuzzel.

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.

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.

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.
