Security & trust
Legally valid and technically reliable
A state-certified crypto core, DSTU compliance, event audit and encryption — all built in Ukraine.
Core principle
Your key never leaves your device
The signature is formed right in your browser. Your private key and password are processed locally and never sent to the server — no plugins, extensions or installs.
State-certified crypto core
The crypto core is state-certified (a positive conclusion from Ukraine's State Service of Special Communications) and runs right in your browser.
Qualified-signature standard
A legally valid QES accepted by government bodies and counterparties; support for international algorithms.
The key stays on your device
The signature is formed locally — the private key and password are never sent to the server.
Signature audit & validation
A history of all document events and full signature verification — certificate chain, OCSP/CRL and timestamps.
2FA & encryption
Two-factor account authentication and encryption of sensitive data at rest.
European track — planned
We plan eIDAS 2.0 / EUDI compatibility for cross-border exchange of legally valid documents.
Your data under control
Where documents are stored, how they're protected, and why you can always take them with you.
Data in Ukraine
Servers and data are hosted within Ukrainian jurisdiction — protected by national law.
Backups
Regular backups on a managed database — your documents won't disappear.
Your archive is yours
Export documents and signatures any time. Data isn't “locked in” — you're in control.
Ukrainian development and jurisdiction
eObig is built in Ukraine. Data and cryptography meet national standards, and the product evolves with Ukrainian requirements and the European eIDAS 2.0 track in mind.
