Hello everyone,

Do you know how to attach a digital signature to a workbook. I designed an
Add-In that validates the workbook, and I want the last macro to digitally
sign it if the validation process is successful. I've seen the help files but
they only contain information about how to do it in Word and the 'signature'
and 'signatureset' classes are not part of Excel's library.

Thanks in advance,
