Cryptography is a process of protecting information by transforming it in cipher text, which is an unreadable format. This information can decipher by only those who have the secret key which convert the message in plain text. Cryptography is very necessary for Network security. The word ‘Cryptography’ is derived from Greek word Kryptos, means hidden. In simple, cryptography has been used to pass coded messages between parties to ensure communication privacy and provide for secure communications between authorized parties while preventing unauthorized parties from monitoring communications.
