Governikus DATA Varuna
Easy validation of electronic signatures and seals

Back to products

Governikus DATA Varuna includes several services for server-side validation of digital signatures, seals and certificates, and for determining the legal level and type of digital signatures based on trust lists in accordance with the requirements of the eIDAS Regulation.

With DATA Varuna's Validation Service, for example, the electronic signature of submitted documents - such as a digital building application - can be verified immediately upon receipt. The integrity of the content and the authenticity of the applicant are thus reliably and accurately determined. Our services for validating digital signatures thus protect against misuse and create legal certainty.

Particularly in the implementation of the Online Access Act services catalog, many application processes can

benefit from this protection against abuse and the added legal certainty.

The services of the DATA Varuna product implement the new European norms and standards for the validation of advanced and qualified electronic signatures and seals, which implement the legal requirements from the eIDAS regulation. All eIDAS-compliant qualified signatures from all EU member states can be validated and verification of Digital-Signature-Act-compliant signatures is still possible.

DATA Varuna is part of the Governikus application of the IT Planning Council.
