Google SSL Checker

Google SSL Checker is a Chrome extension that uses sslchecker.com to provide information about the SSL certification of the currently active tab. It displays details about the SSL certificate, helping users verify its authenticity[1]. Another Chrome extension, TLS/SSL checker and reminder by ElevenGuard, not only checks the SSL certificate but also allows users to set reminders for certificate expiration. It can send notifications via email or Slack.

Google SSL Checker for Android

For Android users, there are apps like SSL Certificate Checker and SSL Toolkit. SSL Certificate Checker provides quick and easy verification and monitoring of SSL certificates on your or other servers. It lists details of Android-validated certificates and displays system messages for invalid certificates[3]. SSL Toolkit offers a range of tools for working with SSL certificates, including checking installed certificates, searching Certificate Transparency Log, and managing Certificate Signing Requests (CSRs).

SSL Checker for IP Address

SSL Checker tools like those offered by The SSL Store and SSL Shopper allow you to verify the SSL Certificate on your web server using the server's hostname or IP address. These tools check if the SSL certificate is properly installed, valid, trusted, and doesn't give any errors to any of your users.

 Checking SSL Certificate Expiration Date

You can check the SSL certificate expiration date manually by clicking on the padlock icon on the leftmost corner of the address bar in your browser, then clicking on the "Connection is secure" label, followed by the "Certificate is valid" label. In the General tab, you can locate the "Valid from…to…" property to see the validity period of the certificate. Tools like TrackSSL and Site24x7 also offer online SSL certificate checkers that can alert you before your SSL certificate expires.

Local SSL Checker

For checking SSL installations on internal names, you can download OpenSSL and run specific OpenSSL commands.

Checking SSL Certificate in Windows and Linux

In Windows, you can enable SSL/TLS in Google Chrome by opening Google Chrome, pressing Alt + f, clicking on settings, selecting the "Show advanced settings" option, and scrolling down to the Network section. In Linux, you can use OpenSSL to manage and check SSL certificates.

 Checking Certificate Chain

SSL Checker tools also display information about the certificate chain, which is the sequence of certificates used to authenticate an entity.

Conclusion

SSL Checker tools are essential for ensuring the security of a website. They provide detailed information about the SSL certificate and help identify and resolve potential issues. Whether you're using a browser extension, a mobile app, or a web-based tool, it's important to regularly check the status of your SSL certificates to maintain the integrity and security of your website.
