Default Multiple independant Digital Signatures [ Office 2007]

I don't know anything about that. You might find something useful at

Thanks Jay. What about utilizing XML signature capabilities? Can we
utlize any XML code inside Word 2007 and then use the XML digital
signature features?

Has this been addressed since 2008? We have need to manage a Word
doc that requires mulitple signatures (at times more than 8),
whereby each is a review/approval for the document and any
additional data placed into the document.

Ideally we would lock down sections of the file after each
signature, i.e. setup a block of information, sign, lock that
section down from editing, but allow edits to the next section.
This is a critical need in an effort to automate some workflows.

Thanks,

Jim

No. As you have discovered, writing the second signature involves
changing the file, invalidating the first signature. A digital
signature relies on a checksum of the file: if you change the file
by as much as a single bit, the signature will be invalid.

Do you know if MS Word [or Excel] 2007 support having multiple
digital signatures [independent of each other] on a single
document?

That is - can I put 3 signature lines on a document, sign it, and
route it to the other two people so that they can sign it also?
Every time I try this the document gets saved when the 2nd person
signs the document which triggers invalidating any prior
signatures. I've tried this in Sharepoint Portal Server 2003,
Outlook email attachments, and finally by putting the document on
a file share and they all result in the same thing happening -
signing the document invalidates any previous signatures.
