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

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.

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)

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

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.

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

Required The folder that contains the libraries to sign.

Optional Recursively search for DLL files.

Optional Url of the timestamp server. Default is 'http://timestamp.verisign.com/scripts/timstamp.dll'
