Matthew-

Thanks for the response. I'll have to dig in to what you said in detail, but it sounds like I'll have at least some facility to test before we submit for the certificate, so I'll proceed on with the development for now.

Thanks,

Paul T.

As I understand it, it works like this:

You can use your WHQL signing key to test-sign your components and add the "Microsoft Test Root Authority" signing certificate to the "trusted root authorities" certificate store on your test system.

This will then cause PUMA to load the component, but in "test mode."

Apps that pass the "allow test mode" flag (test apps) will then work. (Apps that have access to real-live production content [production apps] will *not* pass the flag, and the APIs will [correctly] fail.)

Once everything is tested and working you can submit through WHQL, sign the relevant contracts (Exhibit B), and get a "real" signature. Production apps will then work with your components even with production content.

For an example of passing a "test mode" flag (in this case, to the Trusted Audio Drivers system) see:

submit it for logo certification?
That seems to be a pretty severe restriction, is that really true?
