Today there is large demand of internet applications that requires data to be transmitted in a secure manner. Data transmission in public communication system is not safe and secure because of interception and improper manipulation by eavesdropper. In cryptography technique, the structure of a message is scrambled to make it meaningless and unintelligible unless the decryption key is available. It makes no attempt to disguise or hide the encoded message. Basically, cryptography offers the ability of transmitting information between persons in a way that prevents a third party from reading it.
