What will be the output of the tool?
Make sure that the user data on your website is protected. With the SSL Certificate Checker, you can inspect the following online:
1. Whether your website is accessible via the secure HTTPS protocol.
If users complain that their browser blocks access to the website, you can find the most likely cause with the online Checker.
2. The validity period of the SSL certificate.
You will see until the which date your website's certificate is valid, so you can renew the certificate on time to protect sensitive user data.
What is an SSL certificate?
An SSL certificate is a digital certificate that authenticates a website's identity. The Secure Sockets Layer (SSL) protocol provides a secure, encrypted connection between your website and the user's browser so that hackers cannot intercept user data. You can get a digital certificate for your website from a trusted certificate authority.
When a user accesses a website, their browser verifies the validity of the SSL certificate. It connects with the certificate issuing center and verifies its digital signature. If the certificate is missing or expired, the browser or antivirus software can prevent access to the website.
If a website URL begins with "https", it has a validated SSL certificate and uses a secure transmission protocol over the Internet. With HTTPS, users can enter sensitive data without worrying that somebody may intercept it and use it for their purposes. For example, the username and password for a website account, identity information, bank card details for payment, address for delivery, and other personal information.
How do I check my SSL certificate?
Ensure that your website URL begins with HTTPS and that the certificate is installed. You can check an SSL certificate for free in the online SSL Certificate Checker.
Just enter the website URL and run the Checker. It will verify whether the website is accessible via the HTTPS secure protocol and will show the validity period of the SSL certificate. This way, you will see if users' personal data is secured, and you will be able to renew the certificate on time.
What if my SSL certificate has expired?
As required by the CA/B Forum (the body that regulates the SSL certification industry), the validity period of any SSL certificate is limited. Currently, certificates can be valid for 1-2 years. However, the maximum period is 27 months, i.e., two years and three months to renew the certificate. This restriction is adopted for security reasons so the website owner cannot buy a perpetual certificate and use it forever. Therefore, it is necessary to apply for verification of the authenticity of the website from time to time.
If an SSL certificate has expired, HTTPS will no longer protect user data from hackers. Any browser or antivirus will block website access, resulting in lost search engine positions, traffic, customers, and revenue.
You can renew your SSL certificate in advance or issue a new one before the expiry date. In addition, many hosting companies and domain name registrars provide certificate issuance services.
