Controlled-frame cert inspector

Pick a real-world endpoint and view what a controlled-frame integration would surface via securityInfo — protocol, cipher suite, certificate validity window, OCSP status, and CT proofs. Designed for kiosk and embedded apps that need to verify network identity.

Controlled-frame context. The full API is only accessible from Isolated Web Apps with controlled-frame permission. This page models the security info structure so you can prototype.

// In an Isolated Web App with controlled-frame permission:
controlledFrame.request.onBeforeRequest.addListener(async (details) => {
  const info = await details.getSecurityInfo({ certificateChain: true });
  /* info.protocol, info.cipherSuite, info.certificates[],
     info.certificateValidationResult, info.ctState */
}, { urls: ['<all_urls>'] });
