Hi,
Thank you for coming Microsoft Q&A forum.
As MS Authenticode is not a separated product, it is more likely a measure to support other product, so there is no special tag for it.
For about whitelisting creation, as I know, it is available to create whitelist with AppLocker in Group Policy and use publisher or hash to limit software installation. But as I know, there is no a special product available to create whitelisting with Authenticode, we might need to contact with third party whitelisting software company to check if it is available for them.
Bests,
