check_ssl
Quick HTTPS / SSL check
Checks the HTTPS setup of a public website in a few seconds: TLS certificate (issuer, expiry, trust, name), negotiated TLS version, redirect from HTTP to HTTPS and security headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy). Returns the issues found, most severe first, and a link to the full graded SSL/TLS audit. Passive and non-intrusive: one TLS handshake and two page requests, like a browser visit.
