Cryptography with example
WebSymmetric encryption is the process of converting plaintext into ciphertext and vice versa using the same key. An encryption key is a random string of bits used to encrypt or decrypt data. It is, therefore, important that key is transferred between the sender and recipient using secure methods. RC4, RC5, RC6, IDEA, Blowfish, AES, DES and 3DES ... WebFeb 23, 2024 · 3. Audio Steganography − It is the science of hiding data in sound. Used digitally, it protects against unauthorized reproduction. Watermarking is a technique that encrypts one piece of data (the message) within another (the "carrier"). Its typical uses involve media playback, primarily audio clips. 4.

WebFeb 9, 2024 · The AES Encryption algorithm (also known as the Rijndael algorithm) is a symmetric block cipher algorithm with a block/chunk size of 128 bits. It converts these individual blocks using keys of 128, 192, and 256 bits. Once it encrypts these blocks, it joins them together to form the ciphertext.
