*Cryptography vs Steganography* 👇👇 👉 *Cryptography* is the art and science of secret writing. It is the science of transforming information into an unintelligible form so that it can be saved from unauthorized access. Unlike symmetric Cryptography that rely on one key for both encryption and decryption, asymmetric cryptography or Public Key cryptography is an encryption method that uses two different set of keys - a public key and a private key. The public key is used to encrypt and the private key is used to decrypt the message or information. 👉 *Steganography* is the technique of hiding secret data or message within an ordinary file or message in order to avoid detection and the secret data is then extracted at its destination.
