Signtool.exe succeeds but zero signatures are added to the file
If signtool.exe
succeeds without adding any signatures to the file, it could be due to various reasons. Here are a few possibilities to consider:
Incorrect file path or name: Verify that you are providing the correct file path and name to
signtool.exe
. Ensure that the file exists at the specified location and that you have the necessary permissions to access and modify it.Certificate issues:
signtool.exe
requires a valid code signing certificate to add digital signatures to files. Make sure you have a valid certificate installed on your system and that it is accessible bysigntool.exe
. Check that the certificate is not expired or revoked.Time-stamping server issues: If you are using a time-stamping server for your signatures, ensure that the server is accessible and functioning properly. Time-stamping is important for verifying the authenticity of the signature even after the certificate has expired.
Code integrity policies: Some systems or security configurations may have code integrity policies in place that prevent the addition of digital signatures to certain files or directories. Verify if any code integrity policies are restricting the use of
signtool.exe
or adding signatures to the file.Command syntax or options: Review the command syntax and options used with
signtool.exe
. Make sure you are providing the appropriate signing options, such as the correct certificate, timestamp server, and file to sign. Check the documentation forsigntool.exe
to ensure you are using the command correctly.Antivirus or security software interference: Antivirus or security software running on your system can sometimes interfere with
signtool.exe
or the signing process. Temporarily disable or configure the security software to allowsigntool.exe
to function properly.
If none of these suggestions resolve the issue, it may be helpful to provide more specific details about the command you are using, any error messages or output you receive, and any relevant system or configuration information. This can aid in troubleshooting the problem further.
