Thank you to keytos for providing a base for me to create this action.

Code sign a file

This action signs files that are supported by signtool.exe with a code signing certificate that takes in a password. This action only works on Windows and that means it should run on windows-latest. If openssl is installed on the OS, this action also prints the certificate expiration date to the runner log.

Note

certutil is not used, since it only prints certificate information in a localized format.

Inputs

certificate

Required The base64 encoded certificate.

to get the base 64 encoded certificate of the PFX file, run the following in powershell:

$fileContentBytes = get-content 'YOURFILEPATH.pfx' -Encoding Byte
[System.Convert]::ToBase64String($fileContentBytes)

password

Required Certificate Password. Used to add to the machine store.

certificatesha1

Required SHA1 hash for the certificate. You can obtain this from Microsoft Management Console after double clicking on your certificate (called Thumbprint). This and/or the certificatename is required for the signing to be successful.

certificatename

Required The name of the certificate. This and/or the certificatesha1 is required for the signing to be successful.

folder

Required The folder that contains the libraries to sign.

recursive

Optional Recursively search for DLL files.
