| | In symmetric-key cryptography, we typically distinguish two types of encryption schemes: block ciphers and stream ciphers. Block ciphers divide a plaintext into blocks of a fixed size (e.g., 64 or 128 bits) and encrypt one such block of data as a whole. Stream ciphers, on the other hand, consider the plaintext as a continuous stream of data. The stream cipher maintains an internal state and in ...
