Online Certificate Expiration Date Checker

What are SSL Certificates?

SSL stands for Secure Sockets Layer. It's a type of Internet security technology used when transmitting information over networks in an encrypted way.

Why do SSL certificates have an expiration date?

SSL certificates have expiration dates for a few reasons. One reason is that browsers and other web-based technologies are always updating, and a new SSL certificate with updated security features is needed to ensure that the website is being accessed securely. Additionally, having an expiration date for SSL certificates keeps companies accountable to regularly update their security measures . Because the SSL certificate is used to establish a secure connection between browser and website, an outdated or expired SSL certificate could allow for malicious access to information.

The Dangers of SSL Certificate Expiration

SSL Certificate expiration is a very real danger that can put your services and data at risk. If you don't renew your SSL certificate on time, it will expire and your website can not be accessed without a warning on an up-to-date browser.

Also, when an SSL certificate expires, the data between server and client becomes vulnerable to man in the middle attack. This means that anyone who could gain access to traffic between server and client can try to access data.

How to renew expired ssl certificates?

If you're worried about your SSL certificate expiring, don't panic! There are several ways to renew your certificate before it's too late. Here are a few options:

• Renew your certificate manually: Renewing your SSL certificate manually is the most straightforward option. However, it can be time-consuming and error-prone if you're not familiar with the process.
• Renew your certificate using a third-party service: Renewing your SSL certificate using a third-party service is the easiest way to renew your certificate. These systems are designed to automate the renewal process and make it quick and easy for you.

Last but not least, do not forget that a SSL certificate that has not expired is not secure enough. Certificates must be signed with a Certificate Authority. You can check if your certificate is self-signed or not using our self signed certificate checker tool for free.
