Quick Summary
Perform an instant SSL/TLS security health check on any website. Verify certificate expiration date, issuer authority, cipher strength, and chain validity.

What the SSL Checker Verifies:
- Expiration Countdown: Exact days and hours remaining before renewal is required.
- Issuer Authority: Confirms trusted CA (Let's Encrypt, Cloudflare, DigiCert, Sectigo).
- Protocol & Cipher Suites: Checks TLS 1.2 and TLS 1.3 protocol compliance.
