Description

As a followup for https://bugzilla.mozilla.org/show_bug.cgi?id=1769081, one thing we could do to detect this kind of thing earlier is verify at signing time that (as far as we can determine) all supported windows versions will be able to verify our signed artifact, e.g. by storing CA bundles that contain the trusted CAs for each version and running osslsigncode against that.

Research direction

Start with the signingscript implementation and the linked Bugzilla report, then determine how signing currently handles verification. Done means storing CA bundles for supported Windows versions and running osslsigncode verify against them at signing time.
