Why is Adobe indicating that my signature is invalid?

Adobe is a popular third-part software editor used to view PDF documents and including a function to validate digital signatures.

As any third-part software, Adobe Reader can require a configuration in order to recognize the certification authority for a specific certificate if not in Adobe pre-approved list (https://helpx.adobe.com/acrobat/kb/approved-trust-list1.html).

As you can notice, Notarius is the only organization in Canada member of the AATL* list. However, this is only applicable to our AATL token signature options.

If you want additional information on the process that allows for your Notarius digital signature to be recognized as valid on your computer, please consult the following webpage : /en/help/kb/how-to-configure-adobe-acrobat-to-sign-or-validate-signatures/

 

*AATL : Adobe Approved Trust List.
