ETSI Centre for Testing and Interoperability (CTI) on behalf of TC ESI, ETSI’s Technical Committee for Electronic Signatures and Infrastructures is organizing a remote Plugtests interoperability event on Electronic Signature Validation. This event will be run remotely from 16 May to 10 June 2022 using a dedicated web portal. 


The aim of the event is to check the interoperability of ETSI advanced digital signatures and the validation capacities of the participants in order to help them detect possible issues which may lead to different validation results.

The interoperability testing will allow participants to test their digital signature validation tools and to cross-validate ETSI Electronic Signatures/Seals relying on EU Member States' Trusted Lists (based on TS 119 612 and TS 119 615) and according to the following standards:

  • European Standard EN 319 102-1 (Procedures for Creation and Validation of AdES Digital Signatures; Part 1: Creation and Validation) updated in 2021-11.
  • TS 119 102-2 (Procedures for Creation and Validation of AdES Digital Signatures; Part 2: Signature Validation Report) updated in 2021-09
  • TS 119 172-4 (Signature Validation Policy for European Qualified Electronic Signatures/Seals Using Trusted Lists) updated in 2021-05

These specifications have been updated since the last Digital Signature Validation Plugtests in 2019 and include significant changes.

The signature formats addressed in this event are:

  • XAdES: XML Digital Signature (EN 319 132-1 and ETSI TS 103 171)
  • PAdES: PDF Digital Signature (EN 319 142-1 and ETSI TS 103 172)
  • CAdES: CMS Digital Signature (EN 319 122-1 and ETSI TS 103 173)
  • ASiC: Associated Signature Container (EN 319 162-1 and ETSI TS 103 174)
  • JAdES: JSON Digital Signature (TS 119 182-1)


Registration opens on 16 Feb 2022. All participants must be registered for the event in order to receive their credentials and be subscribed to the mailing list dedicated to this event.

All participants are expected to register individually. Each first person to register within an organization is de facto the official contact from this company for administrative matters.

Registrations will close on 12 May 2022.

The event is free of charge.


By registering to this event, all participating companies join the new ESI Plugtests Programme under which the events conducted will be covered by a single Non-Disclosure Agreement (NDA) that the official contact will receive upon registration. Companies will not be allowed to participate to the event if the Rules of Engagement (RoE) and Non-Disclosure Agreement (NDA) have not been signed. The deadline to sign the RoE and NDAs for the eSignature Validation Plugtests event is 13 May 2022.

The organizations already part of the ESI PLUGTESTS Programme will not be asked to sign the RoE and NDA again.

Credentials to access to the testing web portal will be sent once the portal is open.

This activity is supported by the European Commission and EFTA Secretariat.

All participants are invited to attend the kick-off conf call that is scheduled on Monday 16 May 2022. Invitations to this call will be sent by the ETSI Plugtests Team to all registered participants.

The goal of this meeting is to present how to conduct the interoperability testing and to answer to any of the questions participants may have.

The testing will be performed on a dedicated portal Participants will receive the credentials to this portal before the kick-off meeting on 16 May. 

For an efficient exchange of information, we have also created a slack channel. The participants will receive an invitation to join the slack channel before the event.
