Signatures you can trust
Your key never leaves your computer, and every signature is verified with the NCA of Kazakhstan.
Your keys stay with you
The signature is created locally on your device by NCALayer. The private key never leaves it.
Instant
No queues and no paper. It takes less than a minute.
Legal force
Every signature is checked against the National Certification Authority of Kazakhstan, so the document is valid under Kazakh law.
How it works

No sign-up, no queues — just you, your key and the document.
