A web-based application for the newly developed eGov signature validator has been publicly available at www.validator.ch since December 2021. Documents for signature validation in accordance with the Federal Act on Electronic Signatures (ESigA) can be uploaded manually on the site (web validator). In addition, validation can be carried out automatically via an interface from any specialist applications of the Federal Administration, the cantons or the communes (discrete validator). In this case, instead of the document, only a hash value (a numeric value that uniquely identifies data) is transmitted to the eGov signature validator, and the document itself does not leave the user's infrastructure. The validator is thus an important basic service for electronic government processes.
The eGov signature validator enables electronically signed documents from the Confederation, the cantons and their communes to be verified in one place and according to the same standards. The validator has been used in the pilot canton of Vaud since 2016. Interested cantons can obtain the discrete validator from eOperations Switzerland AG on the basis of a service level agreement and then implement it in the desired specialist applications. Communes obtain the service via the canton.
