TLS & Certificate Check
Live TLS handshake inspection — protocol version, cipher suite, key strength, certificate chain depth, expiry, and signature algorithm. Graded A–F.
Checks included
- TLSv1.3 / 1.2 / 1.1 / 1.0 protocol detection
- Cipher suite: AEAD vs legacy RSA key exchange
- Key bit strength (256-bit EC / 2048–4096-bit RSA)
- Certificate chain depth — leaf + intermediates
- Self-signed certificate flag
- Days until certificate expiry
- Signature algorithm (SHA-256/384 + RSA/EC/PQC)
- HSTS preload eligibility
- HTTP/2 ALPN negotiation
- HTTP/3 Alt-Svc header
