SSL

SSL, or Secure Sockets Layer, is a protocol enabling secure communications over the internet and in particular between a website and the customer’s browser (web browser). Data is encrypted to ensure that no one can access it – e.g. credit card numbers. The customer’s browser presents a warning – usually a small key or padlock – during the secure connection. By clicking on it, the customer can view the merchant’s certificate and check the authenticity of the server.
