I would like to develop a program to sign a Word document from a VB ASP.Net web application using the distributed cryptography capabilities of PKIBlackBox.

I would appreciate it if you could answer the following questions:

1. Is there any sample program to do this?

2. Is the signature embedded in the Word document or it is stored in a different file? If it is embedded, is it possible to embed multiple signatures into the same Word document?

Regarding the sample - we have samples for distributed signing of PDF and XML in Samples\C#\PDFBlackbox\ASPNet_Distributed and Samples\C#\XMLBlackbox\ASPNet_Distributed

Distributed signing of office documents won't be different from the above samples.

And signing itself is shown in Samples\C#\OfficeBlackbox\SecureOffice sample.

I am leaving question 2 for the developer to answer.


Sincerely yours

No. At the moment, there is only C# sample at "Samples\C#\OfficeBlackbox\ASPNet_Distributed"

Yes, the signature is embedded in the document. And yes, it is possible to add more than one signature.

This samples comes with SecureBlackbox 11 pre-release (it was not included in SBB 10)
