SSL certificates are an essential aspect of secure web browsing. They ensure that the website you visit is legitimate, and any data exchanged between the browser and the website is encrypted and secure. Therefore, it is important to know how to check if an SSL certificate is valid from a web browser.
Here are the steps to follow to check if an SSL certificate is valid in a web browser:

Step 1: Check the URL
The first thing to check is the URL of the page you are visiting. Make sure the URL starts with “https” instead of “http”. “Https” means that the website uses SSL encryption, which is indicated by a lock icon on the left side of the address bar.
Step 2: View Certificate Information
Click the lock icon in the address bar to open the certificate information. You can also click on the site’s information icon (usually an “i” or lock icon) on the left side of the address bar, then click on “Certificate” or “View Certificate.”
Step 3: Verify the certificate details
The certificate information window displays various details about the SSL certificate, such as the issuer, the validity period, and the domain name for which the certificate was issued. Check that the domain name listed on the certificate matches the website you’re visiting. If the domain name doesn’t match, the SSL certificate may be fake and you shouldn’t proceed.
Step 4: Check the validity of the certificate
Check the validity of the SSL certificate by looking at the dates listed under “Valid from” and “Valid to”. Make sure that the current date falls between these two dates. If the certificate has expired or is not yet valid, the browser may display a warning or block access to the site.
Step 5: Check the Certification Authority
Check the issuer of the SSL certificate or Certificate Authority (CA). The CA should be a reputable and trusted organization, such as Symantec, Comodo, or Digicert. If the issuer is unknown or untrusted, it could be a sign of a fake SSL certificate.
In conclusion, checking the validity of your SSL certificate is crucial for safe web browsing. By following the steps above, you can verify the SSL certificate of the website you are visiting and ensure that your data remains safe.
