Signature archive

The archive represents a new function of NFQES, it is a way of long-term storage of electronically signed documents, for which the validity period of the certificate will expire. By extending the validity of the certificate in the archive, a chain of signatures is created, which declares that the document has not been changed during the period of validity of the signature.

What is a Hash archive?

Ikona hash archív

A hash archive is a system that stores and protects electronic documents signed with an electronic signature. Its main task is to securely archive the so-called fingerprints, thanks to which we can verify the integrity of the document at any time. Documents in the Hash archive remain valid even after the expiration of the original user electronic signature. It is important, for example, in legal disputes, in the management of companies or in the field of science and research, where it is necessary to be sure that the documents remain intact, and their content is still verifiable.
