Signing NSIS uninstaller from Linux script

[alfageme]

Hi there! think this is the right place to ask this:

We're using an approach to sign our NSIS installer using osslsigncode after creation of the .exe from our cross-compiler script on Linux, all good. However, we realized this way the uninstaller is not getting signed.

Googling the first results for "Signing an Uninstaller with NSIS" I found this example script but we obviously can't get the tempinstaller to run on Linux. Also found this StackOverflow question asking for the same and no apparent solution yet.

So I came to ask the real deal, the NSIS community. Any ideas on how to portably-sign both the Installer and Uninstaller?

(Thought if the uninstaller was created inside the .zip the .exe is in essence, the easy approach was uncompress->sign_uninstaller->compress->sign_installer; but as all you know, the uninstaller is not there but rather is created from the installer with a few tricks)
