Qualified electronic seal

A qualified electronic seal (abbreviated as QES-S) is equivalent to a qualified electronic signature that meets the conditions defined in Act No. 272/2016 Coll. on trusted services and Regulation (EU) No. 910/2014 (eIDAS), which makes it possible to safely, reliably, and unambiguously determine the legal entity that created the signature. QES-S is issued exclusively to legal entities or OVM for the purpose of creating qualified electronic seals, which represent a substitute for a physical seal and handwritten signature of a legal entity. A qualified certificate for a qualified electronic seal is 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 seal within the framework of electronic communication between companies or various public authorities, the commercial sector, and the state itself provides authenticity, integrity and non-repudiation, thanks to which it is possible to unambiguously verify the identity of a legal entity, prove the immutability of signed documents at the time of their signing, and the signed entity cannot claim that he did not make the signature.
