Word 2010 - Sign documents
This manual describes signing a Word document using a digital signature.
Activating the timestamp function
To keep the digitale signature valid after the expiration date, it's required to activate the timestampfunction. By default Office 2010 will use a so-called XAdES-EPES signature, for documents with digital timestamp information this will happen in the XAdES-T format. This setting will need some modifications of the Windows Registry, which are listed below.
- Open Start → Execute → regedit
- Scroll down to the following registerkeys:
- Create a new REG_DWORD datatype named XAdESLevel and set the value to 5
- Create a new REG_DWORD datatype named MinXAdESLevel and set the value to 2
- Create a new REG_SZ datatype named TSALocation and change it's value to the URL of your certificate CA's timestamp server; e.g.
- Open the document you wish to sign and click on File.
- Click on Info → Protect Document → Add a Digital Signature.
- If the document has not been saved yet, a pop-up appears asking the user to do so. Click on Yes.
- Select a location, enter a document name and click on Save.
- Another pop-up appears where you can enter a reason for signing the document and which certificate you want to use. Click on Sign.
- If everything went correctly, a pop-up will appear stating the document has been signed successfully. Click on Ok.
- In the Info screen you will now see highlighted in yellow that the document has been signed, and by whom.
