Qualified electronic signature

A qualified electronic signature (QES) represents information logically connected to an electronic document, which, subject to the fulfillment of the conditions defined in Act no. 272/2016 Coll. on trusted services and Regulation (EU) no. 910/2014 (eIDAS) makes it possible to reliably and unambiguously determine the natural person who made it. QES completely replaces the written form of a handwritten signature, which is achieved by high reliability and security in the identification of a natural person for the purposes of issuing a qualified certificate for QES. It can only be issued by a certification authority, i.e. a company that is a provider of trusted services according to the eIDAS regulation and is registered in the trusted list of providers. The use of a qualified electronic signature within electronic communication provides authenticity, integrity, and non-repudiation, thanks to which it is possible to unambiguously verify the identity of the signed entity, prove the immutability of the signed documents at the time of their signing, and the signed entity cannot claim that it did not make the signature.
