Core expertise

We build cryptography on O‘zMSt

O‘zMSt are Uzbekistan’s national standards for cryptographic information protection. Our whole stack is built around them, not adapted to them after the fact.

O‘zMSt The same production-proven crypto module powers all of our products.

  • Digital signature

    Creating and verifying digital signatures of documents and data using O‘zMSt algorithms.

  • Hashing

    Data integrity control and preparation for signing.

  • Encryption

    Protection of data and correspondence, including end-to-end encryption (E2E).

How it works

Embedded where your users already are

The application calls the client module over WebSocket, while the server module, CA and Verify API complete the chain: signature, status check, authenticity check and timestamp.

Questions and answers

Frequently asked questions

What is O‘zMSt and why does it matter?

O‘zMSt are Uzbekistan’s national standards for cryptographic information protection. Our modules implement O‘zMSt algorithms for digital signatures, hashing and encryption, so the solutions fit the local market.

Which organizations use your solutions?

Our modules and systems are deployed at UNICON.UZ, INFINBANK, as well as in a number of ministries and government agencies of Uzbekistan. E-Hujjat runs in more than 200 government agencies.

Are your modules certified?

The ICRYPTERCLI and ICIPHERCLI server modules and the EMICRYPTER browser module are certified to the national standard.

Which platforms do the crypto modules support?

Server modules, a browser module for web applications, a desktop client application, mobile libraries for Android and iOS, and libraries for Windows, .NET and 1C. SDKs and APIs are available for integration.

Can the CA be deployed on our own infrastructure?

Yes. Our CA is available as a cloud solution and as a self-hosted option. It includes certificate issuance and management, OCSP and a signature verification service.

What about the E-XAT email?

We developed the E-XAT secure email system. The product is now owned by another company, but we can develop a similar system for your organization on our crypto module.
