Frequently Asked Questions
Why is having a valid SSL certificate essential for my website?
An SSL certificate encrypts the data transmitted between your server and your users, protecting sensitive information like passwords and credit card numbers. Additionally, Google uses HTTPS as a ranking signal for SEO.
What details does this SSL checker tool extract?
Our tool retrieves the certificate issuer (e.g., Let's Encrypt, DigiCert), the exact issue and expiration dates, the SSL/TLS protocol version supported, and verifies whether the certificate chain is properly trusted by major browsers.
What happens when an SSL certificate expires?
If your SSL certificate expires, modern web browsers like Chrome and Safari will immediately block users from accessing your site, displaying a prominent, red 'Your connection is not private' warning screen.
Why is my SSL certificate showing as 'Not Trusted'?
A 'Not Trusted' error usually means the certificate was self-signed instead of being issued by a recognized Certificate Authority (CA), or you forgot to install the intermediate certificate chain on your web server.
Does this tool check for outdated protocols like TLS 1.0?
Yes, the tool evaluates the security protocols active on your server. Using deprecated protocols like SSLv3, TLS 1.0, or TLS 1.1 makes your site highly vulnerable to cryptographic attacks and should be disabled.
