What is an electronic digital signature (EDS) in Kazakhstan?

An EDS (electronic digital signature) is a signature on an electronic document, created with the owner’s private key, that lets anyone check who signed the document and whether it has changed since. In Kazakhstan, EDS keys and certificates for individuals and legal entities are issued by the National Certification Authority (NCA RK).

Also called: electronic digital signature

Why it matters

With an EDS, a contract, an act or an ESF e-invoice is signed without a stamp, a scanner or a courier, and the signature can be checked: whose certificate it is and whether it is valid. NCA keys sign documents in the ESF system, and on a company website the signature is built in through NCALayer. That way a customer signs a contract in their account instead of emailing a scan.

1NCA keysCertificates for individuals and legal entities are issued by the National Certification Authority, and keys can also be obtained remotely.
2NCALayerAn NCA program on the user’s computer through which a website gets the signature; it must be running before signing.
3Checking the signatureThe server checks the signature and the certificate status through NCA services and stores the document with its signature.
ExampleA logistics company in Astana emails contracts and acts to customers, who print, sign and scan them. In the customer account, the customer opens the document and signs it with their EDS key through NCALayer, the server checks the certificate, and the signed file is visible to both sides at once.
