The SSL or Secure Sockets Layer is an encryption layer that encodes information that is exchanged between a client and a server. SSL uses two keys − a public key known to everyone to encrypt data and a private or secret key known only to the recipient of the message to decrypt data. An SSL certificate (a file installed on the web server) allows you to apply SSL encryption technology to your site. When an internet user submit sensitive information like identity information, credit card numbers, or confidential records, the SSL certificate turns that information into random letters, numbers and symbols and send it over the internet along with a key to decode the message. Only the program or server that has the proper key can turn the useless information back into usable payment information.
Why your ecommerce Web site needs SSL?
Each SSL Certificate contains unique, authenticated information about the certificate owner and Certificate Authority verifies the identity of the certificate owner when it is issued. SSL technology protects your Web site and makes it easy for your Web site visitors to trust you when dealing with confidential information such as credit card or Social Security numbers ect.
