Secure Socket Layer (SSL)

The internet is a packet-switching network. This means that for two hosts to communicate, they must packetize their data and submit it to router with the destination address prepended to each packet.

Secure Socket Layer is used for protection of data in transit that encompasses all network services using TCP/IP to support typical tasks of communication between the clients and the servers.

It is enable client-server applications to communicate in a way that is designed to prevent eavesdropping, tampering and message forgery.

Secure Socket Layer (SSL) is an encryption technology that runs on top of TCP/IP and below application level protocols, such as HTTP. Secure Socket Layer uses a cryptographic system that uses two keys to encrypt data – a public key known to everyone and a private or secret key known only to the recipient of the message.

Digital Certificate is used for the authentication of web server to the client server. Authentication here means that the web server confirms that it is legitimate/genuine to the client server.

SSL ensures the security of data transported and routed though HTTP. Secure Socket Layer was originally developed by Netscape Communications Corp and RSA Data Security, Inc. and it first appeared in a Netscape Navigator in 1994.
