SSL
Abbreviation for Secure Sockets Layer
In short and in plain language
SSL is the common name for encrypting the link between a browser and a website.
Today a newer method usually does the job. But the old name has stuck in everyday speech.
A valid certificate means that form data is sent encrypted. Then the browser does not show a warning.
