p≡p software

For end-to-end email encryption (Android, iOS, Outlook and Thunderbird), ready-to-use software can be downloaded from pEp.software. For user documentation on those products check the p≡p security documentation.

This Android, iOS, Outlook and Thunderbird software is created by p≡p security, a commercial entity (incorporated in Switzerland and Luxembourg), implementing and shipping p≡p end-user software including professional support.For more information about p≡p security visit pep.security.

p≡p foundation's approach

The foundation itself does not create end-user apps, add-ons and business-oriented solutions, but it provides the necessary core technology (p≡p engine and adapters) and multi-licensing strategy for doing so to a wide range of platforms. It otherwise supports Free/Libre and Open Source Software (FLOSS) to integrate p≡p into their projects.

That's the way the p≡p foundation takes to ensure that every person on every platform can finally have Privacy by Default, by having all their communications automatically encrypted and making the clear text message the exception.

Upcoming end-user software

Active work is being carried out to bring p≡p further desktop platforms (e.g., MS Outlook for macOS and Apple Mail as well as p≡p software for the email clients available under the KDE and GNOME desktop environments). A further plan is to create browser add-ons such as to encrypt web mail and other messaging.

Source code of p≡p's core

• p≡p engine: core to automatize crypto and key management
• p≡p JSON Server Adapter: JavaScript/JSON abstraction to p≡p (use-case: Thunderbird)
• p≡p COM Server Adapter: C#/COM abstraction to p≡p (use-case: Outlook)
• p≡p JNI Adapter: Java Native Interface to p≡p (use-case: Android)
• p≡p macOS Adapter: macOS abstraction to p≡p
• p≡p Objective-C Adapter: Objective-C/Swift abstraction to p≡p (use-case: iOS)
• p≡p Python Adapter: Python3 abstraction to p≡p
• Other core code, including dependencies (libpEpAdapter, pEpMIME etc.) can be found here

Source code of other core software

p≡p is or will rely on further software of which we own the code, too; this software is (co-)financed by us and can also be used independently of p≡p:

• Sequoia PGP: OpenPGP implementation in Rust, usable as a simple library
• GNUnet: P2P framework to (gradually, component-wise) replace the old insecure Internet stack

Source code of end-user software

The foundation gave a trademark license to the commercial p≡p security entity, which is independent from the foundation and creates apps and add-ons for mass end-user and business markets. That entity primarily runs a business model similar to Red Hat's. All that end-user software is accompanied by the source code (in GNU General Public License v3), too:

p≡p security projects:

• p≡p for Android (on K9-fork app basis) source code
• p≡p for iOS (an email client from scratch) source code
• p≡p for Outlook (as add-on) source code
• p≡p for Thunderbird (as add-on) source code
