(Windows) Exporting Your Code Signing Certificate

How to Export Your Code Signing Certificate

Is your code signing certificate stored on a hardware token or hardware security module? Then you cannot export it as a .pfx file with its private key.

These instructions only apply to code signing certificates issued or reissued prior to May 30, 2023; see Code Signing Changes in 2023.

After installing your code signing certificate, you may need to export the certificate for use on a different computer, for signing code, etc.
