What is WinPT?

WinPT (Windows Privacy Tray) is a taskbar utility for doing data en- or decryption. This program is free software under the terms of the GNU General Public License. For this WinPT uses the GNU Privacy Guard, because it's a widely used and free utility for this purposes. WinPT is a so called "frontend" for the GnuPG. The program acts very similar to another program from the PGP(r) package. It supports all common commands for en- and decryption, key transport with the clipboard creation of keys and verification of signatures.

What is GnuPG?

GnuPG is GNU's tool for secure communication and data storage. It can be used to encrypt data and to create digital signatures. It includes an advanced key management facility and is compliant with the proposed OpenPGP Internet standard as described in RFC2440.

What is this page about?

WinPT is a great tool for Windows users to use the features GnuPG offers. To make this tool more accessible for users that do not have time or experience to manually configure both installations I decided to build this package, which automagically install and configures the system. Obviously these packages are not official, but they are also covered by GPL, like almost all programs used to build it (see the Warning at the bottom of this page). You can download the source code of all of them and check by yourself.

The installation script actually contais some code from Nelson E. Ingersoll (OpenPGP Key ID: 0x03C2B93B).


This package is built and maintained by Gustavo Vasconcelos (aka Tango). If you have any trouble using or installing this package, feel free to mail me.

This package includes software from several sources:

The latest version is winpt-0.7.92-installer-v5.exe, released 25/11/2002 22:07 (GMT+0300). This version is fully upgradeable from the latest 0.7.91 and 0.7.92-v1/2/3. It was built with WinPT 0.7.92 (13/11/2002) and GnuPG 1.2.1-nr1 (Nullify Release 1). This version now includes Windows Privacy Tray Explorer Extensions (WinPTEE), a context menu shell integration.

The only difference between V3 and V2 is the shell integration.
The V4 was built, but never released. Download V5, instead, which now includes WinPTEE or V3.

For the ones only interested in WinPTEE, there is a standalone version of the instaler, just with WinPTEE.dll and OpenCDK.dll (and the  default public keyring). This version does exactly the same the official zip file does plus a default keyring (in the case none exists), but is a lot simpler to install.

Inno Setup Scripts used to build the installers. Only latest version is avaible. Older versions are always overwritten.

  • Translation file for Brazilian Portuguese (remove the "-pt_BR" from file name and save in the locale folder)


  • Included GPGOE into the package;
  • Included WinPTEE into the package;
  • Uses module extensions from Disastry for IDEA;
  • Uses GnuPG build from Nullify;

  • Installer does not continue while WinPT is running;
  • Nice images with GnuPG and WinPT logo ;-)
  • Some minor tweaking.
