MPC Demo — Compute on Encrypted Data

Watch how 3 parties compute 42 + 7 without any party seeing either number

1 Split secrets into shares

Splits both secrets into shares so no single party sees them

TLS Certificate Checker

Check TLS/SSL certificate expiry, issuer, and security configuration. Paste openssl output for instant analysis.

Prompt Injection Tester

Scan prompts and untrusted content for injection patterns: overrides, exfiltration commands, hidden Unicode, encoded payloads. Includes attack payloads and the Lethal Trifecta checklist.

OWASP ZAP Report Analyzer

Paste an OWASP ZAP JSON or Markdown scan report and get a triaged summary: risk counts, affected URLs, CWE links and fix guidance. 100% client-side.

About the MPC Demo

Multi-party computation lets parties jointly compute a function while keeping their inputs private — add numbers without anyone seeing the addends. It powers private auctions, confidential AI, and sealed-bid workflows.

This walkthrough splits values into additive shares, passes them between virtual parties, computes on the shares, and reconstructs the result — every intermediate value visible so you can verify nothing leaks. The demo runs entirely in your browser.

How to use

  1. Enter each party's private input.
  2. Step through the sharing, computation, and reconstruction.
  3. Inspect every message to confirm inputs never appear in the clear.
