What is a qualified electronic signature (QES)?

Under both Swiss and EU laws, the qualified electronic signature is the type of eSignature with the highest evidential value, and the only one that is legally equivalent to a handwritten signature.

Overall, Swiss and EU regulations define three types of eSignature: the qualified electronic signature (QES), the advanced electronic signature (AES) and the simple electronic signature (SES).

Is DeepSign compliant with document signing standards under EU and Swiss law?

Yes.

Two of the electronic signatures DeepSign offers meet the statutory requirements for electronic signatures in the EU and Switzerland: the advanced electronic signature (AES) and the qualified electronic signature (QES). They are issued by qualified trust service providers (QTSP) and certification authorities in the EU and Switzerland. This also applies to the qualified timestamp used in the simple electronic signature (SES).

Can I select signatures that are regulated under different jurisdictions?

To decide which legal system is required for a signature, it is important to consider the content of the document for which you want to obtain the signature. You may need one regulated by the Swiss law or by another legal system.
When a document is sent for signing, the sender selects the jurisdiction (Switzerland – ZertES; EU – eIDAS) which legal requirements the electronic signature should meet. The selection is then displayed on the visual signature element of the document.

How do I know which type of signature to use?

DeepSign offers three types of electronic signatures recognised by international regulations: simple electronic signatures (SES), advanced electronic signatures (AES) and qualified electronic signatures (QES).

The type of electronic signature that you need to use in each case depends on the written form requirements for the relevant document, your contractual agreements and your company policy.

To find out the appropriate type for your specific situation, please consult with a legal advisor.

Simple electronic signatures (SES)
For documents with no written form requirement. A qualified electronic timestamp guarantees document authenticity. Useful when there are no written form requirements. Also suitable for digital document retention solutions.

Advanced electronic signatures (AES)
For documents with no written form requirement. With this type of signature, the signatory is identified in advance. It not only ensures that the documents are authentic but also that they are properly linked with the signatory.

Qualified electronic signatures (QES)
For documents subject to written form requirements under EU or Swiss law. With this type of signature, the signatory is identified in advance. It not only ensures that the documents are authentic but also that they are properly linked with the signatory. In addition, it is issued with a qualified certificate from a qualified trust service provider (QTSP). The QES therefore is legally equivalent to a handwritten signature.

How can I verify if a qualified electronic signature (QES) used to sign a document is legally valid?

The use of qualified electronic signatures offers crucial validation capabilities, including cryptographic proof and secure identity verification. These features are key to assess and authenticate electronic signatures.

There are two specific methods to confirm the validity of a QES, each aligned with different regulatory standards:

EU validator:

Accessible on the European Commission’s website by clicking the button above, this web-based application is designed by the European Commission to verify QESs in compliance with the EU regulation (eIDAS). Users can upload their signed document to obtain a comprehensive validation report. This tool requires an internet connection to access and download the report, which can serve as a digital certificate of authentication.

Swiss validator:

Available on Federal Chancellery’s website by clicking the button above, this platform verifies that a document is correctly signed with a QES according to the Swiss law (ZertES). By uploading your document to the official Swiss validator, you can quickly obtain a validation report, ensuring compliance with Swiss standards.

Each tool is tailored to specific regulatory environments: the EU DSS Tool is for validation under the EU regulations, while the Swiss Validator is essential for verification under the Swiss law. Both are reliable tools to authenticate the integrity and legality of electronic signatures according to the related legal framework.
