License Server Certificate |
|
|
Hi Tim
We have a complete DRM system up and running already. We currently package server side using ASP. However our clients have the need to do the packaging on their machines. So we need a client side DRM packager. I cant find any info on how to achieve this. Some of my contacts have said i can use a client side programming language (we are using C# .NET) and the wmrmobjs.dll to do this. However this dll needs the license server certificate to work, so its not a good solution.
1. Is it true that we can use wmrmobjs.dll in our client application legally?
2. And if this is not the right approach, can you provide us with some detailed info on how to build a client side packaging application?
3. I have a thorough understanding of how the encryption keys and signing keys work. But i dont know for sure exactly what the license server certificate does. Just what does it do?
4. Using the MS License Server certificate, is it secure especially as clients will be using it. Is there an alternative certfication that can be implemeneted.
Thank you for your help.

Hi M.
1) I can't comment on the legality as I am only a tester. But wmrmobjs.dll
version 10 is only installable on server 2003.
2) I'll have to ask the developers. But I don't think there is.
3) The certificate helps identify who created the packaged content. If the
person/company is not authorized to package that content the certificate can
be revoked and the person/company can no longer package content.
4) There is no personal information in the certificate. The certificate
contains a certificate number which is used to identify owner of the
certificate in Microsoft's certificate owner database. Related to answer
#3.

1) It's pretty well illegal and non-practical to
distribute the wmrmobjs.dll object (including just the
certificate problems).
However a client side packager can be built using the
Format SDK and c++.
If you'd like more info I have a functioning packager I
built for an older project so drop me an email.
