yes, this is related to our discussion about MS-PAR.

(1) This is in conjunction with our previous discussion about [MS-PAR].
(2) This is about MS-PAR. Package aware v3/v4 printer drivers ship an .inf
file and a .cat file. The .cat file is a Microsoft Catalog file. It is a DER
encoded PKCS#7 certificate with embedded data. The embedded data is a
Certificate Trust List (CTL).
To be able to verify the Catalog file (the PKCS7 signature) which is shipped
with a driver I need a copy of the certificate. I guess it is stored in the
I guess the Catalog file is validated before the driver gets copied to the
driver store. But that's probably an additional question. I think we should
collect questions about MS-PAR and send them to dochelp.
Thanks so far.
