SMT Cryptographic Labs

Zero-Knowledge Security Playground

Verify our client-side encryption mathematical proofs and independently cross-verify using neutral, open-source cryptographic utilities like CyberChef (maintained by GCHQ).

Technical Note: CyberChef is an independent, open-source tool maintained by GCHQ. This page shows technical cross-verification using CyberChef — it is not an official endorsement or certification by GCHQ.

Frequently Asked Questions

Clarifying our relationship with third-party tools.

Q:Is Simple Money Tracker endorsed by GCHQ?

A: No. We use CyberChef — an open-source cryptographic utility maintained by GCHQ — as a neutral tool to let anyone verify client-side encryption.

This demonstrates the math and reproducibility; it is not an endorsement by GCHQ or any government body. We do not have any relationship with GCHQ.

Q:Why use CyberChef for verification?

A: CyberChef is a globally recognized, "neutral" cryptographic workbench. By showing you how to decrypt your data using a third-party tool that SMT does not control, we prove that your security relies on universal mathematics, not our proprietary code.
