    To verify if a document has changed after signing (has integrity), Acrobat or Adobe Reader must have a way to uniquely identify what was signed. To do this, it uses a message digest. A message digest is a number which is created algorithmically from a file and which uniquely represents that file.

    Documents with multiple signatures contain the elements needed to reconstruct any previous version of itself as it existed at the time of signing.

Therefore, it may be necessary to view the signed version in order to see what content was actually signed.
