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

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.

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

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.

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.

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

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.

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

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.

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.

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.

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).

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

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.

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 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.

QGpgme provides a very high level Qt API around GpgMEpp.

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.

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.

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

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

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.

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.
