Summary

Step by step guide on how to sign Authenticode with a Code Signing certificate.

Signing Microsoft Authenticodes

This is the procedure you use to sign files using Microsoft Authenticode (.exe or .msi files, for example) with an Entrust EV Code-signing certificate.

Before you begin this procedure you must have:

• an Entrust EV Code Signing certificate (installed on a token)
• correctly installed and configured the SafeNet Authentication Client version 10.7, to manage the token

Note: See the Entrust Code Signing and EV Code Signing Certificate Download and Installation Guide for specific information about configuring the SafeNet client . Code Signing Certificate Installation Guide

• installed the Microsoft Windows Software Development Kit. The kit is available from https://msdn.microsoft.com/en-us/windows/desktop/bg162891.aspx

To sign a file with an EV Code Signing certificate:

Note: The following procedure uses SignTool to sign the file.

1. Connect the token with your EV Code signing certificate to the USB port of your computer.
2. Open a command line window and change directory to the location of SignTool on your machine. By default this is: <drive>:\Program Files (x86)\Windows Kits\<version>\bin\x86
3. Run the following command to sign your file:

signtool sign /fd SHA256 /td SHA256 /a /tr "<timestamp address>" "<drive:\yourfilename.<extension>"

Example:

signtool sign /fd SHA256 /td SHA256 /a /tr "http://timestamp.entrust.net/rfc3161ts2" "C:\test.msi"

4. Enter the password for the keystore when prompted, and click OK . Use the password that you created for the token.

SignTool returns a message similar to the following:

Done adding additional store Successfully signed: C:\test.msi

5. You can verify that the file has been signed correctly by running the command below:
   
   SignTool verify /pa /v <filename>

The output should contain specific information about the certificate chain and the timestamp, as well as a success message for verifying the certificate.
