System Documentation

What problem does it solve?

It removes guesswork when you need to understand how a domain’s TLS is configured by extracting certificate details and network fingerprint signals.

Core Features & Use Cases

  • Certificate metadata extraction: Pulls issuer, Subject Alternative Names (SANs), validity window, signature algorithm, and public key details from a live TLS endpoint.
  • Issuer and hosting inference: Maps issuer patterns (e.g., Let’s Encrypt, DigiCert, AWS, Cloudflare, Google Trust Services) to technology and operational signals with confidence.
  • Protocol support checks: Determines supported TLS versions (1.0 through 1.3) to surface legacy exposure or modern-only posture.
  • Optional JARM fingerprinting: Generates a server fingerprint to aid technology identification and matching against known fingerprint patterns.

Quick Start

Ask the AI to analyze the TLS certificate and TLS protocol support for the domain example.com and return issuer, SANs, protocol versions, and any known JARM match.
