Technical Specifications & Overview
What is an SSL Certificate Checker?
An SSL Certificate Checker connects directly to your web server via TLS/SSL protocol on port 443 to inspect the cryptographic certificate issued to your domain name. It verifies that your HTTPS encryption is active, identifies the Certificate Authority (such as Let's Encrypt, Cloudflare, DigiCert, or Sectigo), and calculates the exact days remaining before expiration.
Why Monitor SSL Certificate Expiration?
An expired SSL certificate immediately triggers alarming full-page browser security warnings (such as NET::ERR_CERT_DATE_INVALID in Chrome), causing immediate traffic collapse, lost revenue, and severe SEO rank degradation. Regular verification ensures automated renewal systems (like Certbot or ACME) are operating without failures.
Key Certificate Details Inspected
- Common Name & SANs: Verifies domain coverage including wildcard and multi-domain hostnames.
- Valid From & Valid To: Timestamped validity window.
- Signature Algorithm: Cryptographic hashing verification (e.g., SHA-256 with RSA).
- Days Remaining: Visual alert countdown for expiring certificates.
