Signing a Workbook

Excel 2007 supports two types of digital signatures: a visible signature and an invisible signature.

To add a visible digital signature, choose Insert => Text => Signature Line => Microsoft Office Signature Line. Excel displays its Signature Setup dialog box, and you are prompted for the information for the signature.



After you add the signature box, double-click it to display the Sign dialog box, where you actually sign the document either by typing your name or uploading a scanned image of your signature.

A document with a visible digital signature.



To add an invisible digital signature, choose Office => Prepare => Add a Digital Signature.
