In today’s internet, SSL certificates are no longer optional—they’re essential. From search engine rankings to user trust, SSL plays a crucial role in keeping your website secure and professional. But what if you need to quickly check whether your SSL is installed correctly, when it expires, or who issued it?
That’s where the SSL Certificate Checker on 99tools.in comes in. This free online tool lets you instantly analyze a website’s SSL setup, helping developers, website owners, and IT admins keep their domains secure.
🧭 What is an SSL Certificate?
An SSL (Secure Sockets Layer) certificate is a digital certificate that encrypts communication between a website and its visitors. Today, SSL has been replaced by its successor TLS, but the term “SSL certificate” is still commonly used.
When a website has SSL enabled, you’ll see a padlock icon in the browser and the URL will start with https://. Without SSL, user data (like login credentials, payment info, and personal details) can be intercepted by attackers.
⚡ Why Use an SSL Certificate Checker?
An SSL certificate checker helps you:
- ✅ Verify installation – Confirm that SSL is set up correctly for your domain.
- ✅ Check expiry date – Avoid unexpected downtime by renewing your certificate before it expires.
- ✅ Confirm issuer & validity – See which Certificate Authority (CA) issued your SSL and whether it’s trusted.
- ✅ Analyze certificate chain – Ensure intermediate certificates are properly configured to prevent browser warnings.
- ✅ Improve SEO & trust – Google favors HTTPS sites, and visitors are more likely to trust a secure domain.
🔍 What Information Does the SSL Checker Provide?
When you enter a domain, the tool runs a check and returns key SSL details:
- SSL Status – Whether SSL is active on the domain.
- Expiry Date – The date your certificate will expire.
- Issuer Details – The Certificate Authority (e.g., DigiCert, Let’s Encrypt, Sectigo).
- Certificate Chain – A breakdown of the full trust path (root → intermediate → domain certificate).
- Common Name (CN) & SANs – The primary domain and any additional domains secured.
- Encryption Strength – Cipher details (optional advanced info).

Many website owners forget to track SSL expiry. When a certificate expires, visitors will see warnings like “Your connection is not private”, which:
- Damages your site’s credibility.

Regularly checking your SSL certificate ensures your site remains secure, trusted, and uninterrupted.
