🔒 SSL Certificate Checker

What is SSL/TLS?

SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are cryptographic protocols that encrypt data between your browser and websites.

Why SSL Matters

• Encryption — Protects data from eavesdroppers
• Authentication — Verifies website identity
• SEO Ranking — Google prefers HTTPS sites
• Trust — Users see padlock icon in browser

What to Check

Certificate validity, expiration date, issuer (CA), and whether the site uses modern TLS 1.2 or 1.3.
