Secure file and email exchange! Usable for everyone without licensing fees. Transparent with source code using Open Standards.

This is the wiki of [[http://gnupg.org|GnuPG]] and all ~GnuPG related Free Software initiatives, e.g. [[http://gpg4win.org|Gpg4win]] (~GnuPG for windows).

It's all about end-to-end security software where **you do not have to trust a (third party) server** or transport system.
It uses openly researched crypto algorithms.
The implementations can be independently verified.

The next big user experience boost for email security would be the adoption of the [[https://g10code.com/steed.html|STEED]] concept. Help us make it happen.

== Documentation
Aim of this wiki is to help users and contributors by providing a central place for [[documentation]], links to references and planning.

==== Building GnuPG 2.1
GnuPG 2.1 is the latest GnuPG version but as with all 2.x versions it has several dependencies which makes building a bit more difficult.  Here are some infos.
