You can use your DigiCert® Document Signing Certificate to add an invisible digital signature to a Word document, Excel workbook, and PowerPoint presentation. Because the signature does not appear in the document, a small signature icon appears at the bottom of the page to let recipients know that the document has been signed. For more information about DigiCert® Document Signing Certificates, see DigiCert Document Signing Certificates.
You can also use your DigiCert® Document Signing Certificate to add a visible signature inside a Word document or Excel workbook. See How to Sign Microsoft Office Documents: Office 2013, 2010, and 2007.
