This is the official Wiki for [[http://gnupg.org|GnuPG]], the GNU Privacy Guard, and all ~GnuPG related Free Software initiatives, e.g., [[http://gpg4win.org|Gpg4win]] (~GnuPG for windows).
The aim of this Wiki is to help users and contributors by providing a central place for [[documentation]], links to references and planning.
We welcome your contribution!

GnuPG:

* enables end-to-end security without **the user having to trust a third party server or transport system.**
* uses openly researched crypto algorithms.
* is free software and, as such, the implementation can be independently audited.

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.

 * LargeKeys?

== GnuPG

 * PlatformNotes - what to be aware of when using or administrating ~GnuPG on different platforms.
 * [[X.509]] hints (needed for S/~MIME and trusted root certs)
 * SmartCard hints

==== Building GnuPG 2.1

GnuPG 2.1 is the latest GnuPG version but as with all 2.x versions it has several dependencies, which make building it a bit more difficult.  Here are some notes.

  * [[Build2.1_Windows|Building for Windows]]

==== Various links

 This is a collection of links:

 * [[http://upstream-tracker.org/|Upstream-Tracker.org]] checks ABI/API changes for some libraries like [[http://upstream-tracker.org/versions/gpgme.html|gpgme]],
[[http://upstream-tracker.org/versions/libgpg-error.html|libgpg-error]],
[[http://upstream-tracker.org/versions/libgcrypt.html|libgcrypt]].

   Note that the tools can't necessary decide whether something is an ABI or API
   change.  The output should be used as a hint to look for whether there
   might be a problem.  We are not aware of any broken API or ABI
   contracts for the listed libraries.
