Validator for digital documents

In order to increase the acceptance of electronically signed documents among recipients, they need a way of checking the authenticity and integrity of the document received. This is where signature validation comes in. A signature validator should be made available to the recipients of electronically signed cantonal (official) documents.

Description of target state

The existing possibilities for electronic signatures in official documents for the G2C, G2B and G2G processes are to be supplemented by signature validation. In 2013, the Federal Office of Justice established an internal document validator within the Confederation. The Federal IT Steering Unit took this over and turned it into a standard service for the Federal Administration. In the strategic project, the FITSU will first carry out a pilot project that will make it possible to define the signature validation of official documents and examine selected documents from the canton of Zug. Subsequently, the version of the validator should be made available for other authorities, and its usage in cantonal (and possibly communal) administrations should be promoted up to the end of 2019.

Measures supported in the strategic plan

Implementation status of the validator for digital documents

At present, the recipients of official, electronically signed documents from the Federal Administration have the option of checking signatures using the signature validation standard service (validator.ch). This service is already in use.
It is planned for the validation rules of the pilot application to be added to the existing service.
