WinPT or Windows Privacy Tray is frontend to the Gnu Privacy Guard (GnuPG) for the Windows platform. Released under GPL, it is compatible with OpenPGP compliant software.
WinPT represents a collection of user interface tools designed to ease the use of asymmetric encryption software. Based on GnuPG, and OpenPGP-compatible, WinPT is intended for Windows users to use for everyday message signing, verification, encryption and general key management.
If installation defaults are used, WinPT will then reside in the task bar tray, and on the right-click menu within Windows Explorer. A Start menu item includes launchers for a GPG commandline (console), WinPT tray, and documentation.
On April 4, 2007, the project's author, Timo Schulz, announced that development on WinPT has been suspended for an indefinite period.
However on October 27, 2008, Schultz announced a new version 1.30, described as a bug fix release.
On December 14, 2009, Timo Schultz announced that WinPT is discontinued due to lack of resources.
