Authenticating workbooks
If you have several certificates from which to choose, and the desired certificate doesn’t
appear in the Sign dialog box, you can click Change to display the Select Certificate dialog
box. In the Select Certificate dialog box, click the certificate with which you want to sign the
workbook, and then click OK. The Select Certificate dialog box closes, and the certificate
with which you signed the workbook appears in the Sign dialog box. As before, click Sign to
sign your document by using the digital certificate.
In this exercise, you’ll create a digital certificate and digitally sign a workbook by using the
certificate.
IMPORTANT You must have a digital certificate, such as one generated by selfcert.exe or
purchased through a third-party vendor, to complete this exercise. If you don’t have a
thirdparty digital certificate and don’t have selfcert.exe installed on your computer, read through the
steps of the procedure to become familiar with the process.
SET UP You need the ProjectionsSigned workbook located in the Chapter14 practice
file folder to complete this exercise. Open the workbook, and then follow the steps.
1 On the drive where you installed Office 2013, navigate to the folder (such as
C:\Program Files (x86)\Microsoft Office\Ofice15 ) that contains the Office 2013
program files, and then double-click selfcert.exe . The Create Digital Certificate
dialog box opens.
