Digital Signatures

Anyone use/know of any software that I can use to sign documents (Word, Excel, PDF, etc) with domain account credentials? Essentially digitally signing the document to the user that is currently logged in?

Interesting requirement - I've never come across a similar situation. Do let us know if you end up finding something cause it sounds really interesting!!

I'm assuming were talking about Digitally Signing via SSL certs similar to any HTTPS:// website to verify ones identity and ensuring a secure connection? Or is it like when someone finishes a document its has their signature on the bottom?

You can sign a document in office. Say in word 2003:

1.On the Tools menu, click Options, and click the Security tab.
2.Click Digital signatures.
3.Click Add.
4.Select the certificate you want to add, and then click OK.

But as you know, the user needs a digital certificate, and to get one you need a certificate authority. I believe Windows 2003 server (or Active Directory) can work as a certificate authority. But I have never tried this. This might help:

You can on the other hand create a self signed certificate (i.e without a certificate authority) in MS Office. But I believe that's not what you wanted.

The signature assures that any changes made to the data that has been signed can not go undetected. A digital signature can be used with any kind of message, whether it is encrypted or no. It is easily transportable, cannot be imitated by someone else, and can be automatically time stamped.
