Hi,
we been using Certum certificates to sign PDF documents. Recently I noticed the Certum CA was removed from the AATL?
So I have got the following questions @ Adobe:
1) Is there a way, to validate signatures with Certum certifcates signed in the past?
2) Which certificates are guaranteed not to be removed from the AATL to avoid such a disaster in future!
Thank you & regards
