Cryptography is a way to provide security to the message which is passed between the sender and the receiver. It uses various algorithms to convert the actual message to an unreadable form. Steganography is an art of hiding the message in an medium. The medium can be audio, video, image or even a graph. It gives the security through the medium. The crypto-stegno communication uses both cryptography and steganography to send the message secretly from the sender to the receiver. This paper shows the usage of how message from sender is encrypted using triple DES through Unicode and hide the encrypted image into an stego image.
