An SSL certificate is a special feature that is installed on a website so that data can be transmitted over SSL. SSL stands for Secure Sockets Layer, translating the level of secure sockets. This protocol provides secure data transfer between the server on which the website is located and the user’s browser.
SSL certificates contain information about individuals or organizations’ website. The presence of an SSL certificate on the website is easy to verify by simply looking at the line with the website address in the browser. In the address bar you (depending on the certificate chosen by the website owner) you will see:
- a closed lock icon, when you click on it you will see the phrase “Secure Connection”, and you can also get more detailed information about the installed certificate;
- or next to the lock icon, the name of the company that owns the website will also be indicated.
If the SSL certificate is not installed on the website, then “Not Protected” will be written in front of the address.
