Why did some validated signatures on electronic documents become invalid?

Adobe revoked multiple digital certificate chains from their Trust List

Adobe runs a trust program named AATL (Adobe Approved Trust List) for validating the Trust Qualification of the certificates used in PDF document signatures / stamps.

Several certificate issuance entities, who also issue certificates stored in software, were not accepted in the AATL program.
However, since they are not accredited as entities under the eIDAS Regulation, they have issued NON-QUALIFIED certificates using these same certification chains.
This situation was detected in 2018 by both the European Union and Adobe, who initiated the necessary correction processes, which have resulted in the recent policy update by Adobe.

This policy change marks as “invalid” (represented by the symbol ) any signature / seal associated to unqualified certificates issued by EUTL “qualified” entities.

DigitalSign was not affected by this Adobe's decision, since such unlawful practices were never carried out by this Certificate Issuance Entity, having always condemned such irregularities in the appropriate agencies.

In that sense, DigitalSign offers all affected customers an immediate solution to address this issue, according to the European eIDAS regulation and Adobe itself.
