To check the validity of a certificate, follow these steps:

  1. Have the operating certificate:
    • If it is in software you will have it installed in your internet browser (Firefox, Chrome, Explorer, etc.)
    • If it is on a device (card or USB memory), you will have it connected to your computer.
  2. Once step 1 is confirmed, access the website
  3. If you have more than one certificate, you will be asked to select the one you want to check.
  4. When the page loads, you will be shown the certificate information.

How to interpret the results: Both the time you select the certificate and the fact that you see the results page confirm that the certificate is working properly. In addition, on the page you can see the basic information of the same (special attention to the final date of validity).
