🔏 Security Tool

SSL Certificate Checker

Verify SSL/TLS certificates for any domain. Check issuer, expiration, protocol version, and overall SSL health of your website.

Understanding SSL/TLS

Version Status Security
SSL 2.0 ❌ Deprecated Critically insecure
SSL 3.0 ❌ Deprecated Vulnerable (POODLE)
TLS 1.0 ⚠️ Legacy Weak (should disable)
TLS 1.1 ⚠️ Legacy Weak (should disable)
TLS 1.2 ✅ Current Secure (widely used)
TLS 1.3 ✅ Latest Most secure & fastest

Why SSL Certificates Matter

SSL/TLS certificates encrypt the connection between your website and visitors, protecting sensitive data like passwords and credit card numbers. Google also uses HTTPS as a ranking factor — sites without SSL are penalized in search results and shown as "Not Secure" in browsers.

Types of SSL Certificates

Type Validation Use Case
DV (Domain Validated) Domain ownership only Blogs, small sites
OV (Org Validated) Organization verified Business websites
EV (Extended Validation) Full legal verification E-commerce, banking
