This project is about the secure transfer of files using cryptography and steganography. Securing data encryption and decryption using cryptography and steganography techniques. Due to recent developments in stego analysis, providing security to personal contents, messages, or digital images using steganography has become difficult. By using stego analysis, one can easily reveal the existence of hidden information in carrier files. This project introduces a novel steganographic and cryptographic approach for communication between two private parties. The approach introduced in this project makes use of both steganographic as well as cryptographic techniques. In cryptography, we are using Caesar cipher. In steganography, we are using image steganography for hiding the data. And we also use the mutual authentication process to satisfy all services in cryptography i.e., access control, confidentiality, integrity, authentication. In this way, we can maintain the data more securely. Since we use the Caesar cipher algorithm for securing the data and again on this, we perform steganography to hide the key in an image. Such that any other person in the network cannot access the data present in the network. Only the sender and receiver can retrieve the message from the data. The sender receives the key hidden in the image using steganography. After receiving the image, the receiver retrieves the key from the image and then decrypts the files using the key.
