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. WebMost cryptographic processes use private key encryption to encrypt data transmissions. They typically use a public key algorithm to securely share secret keys. Work for stream and block ciphers. Secret key ciphers -- the algorithm for encrypting and decrypting data -- generally fall into one of two categories: stream ciphers or block ciphers.

WebFeb 23, 2024 · Steganography is a form of encryption that protects the information within a message and the connections between sender and receiver.
