Install SignTools

SignTools is a Windows command-line tool that uses Authenticode to digitally sign files and verify both signatures in files and timestamp files. SignTool is available as part of Microsoft Windows SDK, which can be installed in just a few easy steps.

1. Download the latest version of the SDK for the most recent stable version of Windows from the Windows SDK and emulator archive. Make sure to select "Install SDK".

2. Double-click the downloaded file. There's no need to change the default installation path. Click "Next".

3. There's no need to enable Microsoft Insights collection, so select "No" and then click "Next".

4. Install the necessary SDK package.

The Windows SDK installer provides a number of different packages that can be installed. The only package needed for gpg4win verification is Windows SDK Signing Tools for Desktop Apps (SignTools). Choose it then press on "Install".

5. Once the installation is complete, close the installer.

Download and Verify Gpg4win

SignTool can be used to verify the authenticity of the gpg4win package itself.

Note: To simplify the SignTool verification process, be sure to download the gpg4win package to the Downloads directory.

1. Download the gpg4win package.

• Navigate to https://gpg4win.org/
• Download the latest version of gpg4win.

At the time of writing gpg4win-4.3.1.exe was the latest version.

2. Verify the gpg4win package by running SignTool from the command prompt.

Now you need to manually locate signtool.exe and run it as a normal *.exe file. You will need to provide a path to your gpg4win-latest.exe file. Open PowerShell then add the following:

Notes:

• Replace [username] with your computer's username; the uploaded image uses "techy" as an example.
• Replace gpg4win-[version number].exe with the version of the downloaded gpg4win file..

& "C:\Program Files (x86)\Windows Kits\10\bin\10.0.22621.0\x64\signtool.exe" verify /pa "C:\Users\[username]\Downloads\gpg4win-[version number].exe".

Warning: If verification fails, delete the gpg4win package and repeat the download and verification process again.

If verification passes, then you are ready to trust and install gpg using this file, i.e., gpg4win-latest.exe.
