What Is an SSL Certificate?

An SSL/TLS certificate helps establish an encrypted connection between a website and a visitor's browser. Websites using HTTPS use certificates to help protect data exchanged between the client and server.

An SSL certificate can also contain information about the certificate authority, validity period, and domains covered by the certificate.

What Does the SSL Checker Check?

The SSL Checker can provide available information such as:

SSL certificate status
Certificate issuer
Issue date
Expiry date
Certificate subject
Domain coverage
Subject Alternative Names (SANs)
Certificate details
HTTPS certificate information
Certificate validity

Why Use an SSL Checker?

SSL Checker vs SSL Certificate Checker

An SSL Checker focuses on checking the SSL/TLS certificate and related HTTPS information for a website.

An SSL Certificate Checker is commonly used for the same type of certificate inspection, including issuer, expiry, validity, and domain coverage.

The terms are often used interchangeably when referring to online certificate checking tools.

Limitations

SSL certificate information can change when a certificate is renewed, replaced, or reconfigured. Results may also depend on the server, CDN, proxy, or hosting configuration responding to the request.

A valid SSL certificate does not guarantee that a website is completely secure. It does not by itself check for malware, vulnerabilities, insecure application code, or other website security issues.
