WebbIn cryptography, a cipher (or cypher) is a method for protecting data through encryption and decryption. Most ciphers require a specific key for encryption and decryption, but … WebbThis is also referred to as symmetric key encryption. There are two types of symmetric algorithms (or ciphers): stream and block. A block cipher divides the data into blocks (often 64-bit blocks, but newer algorithms sometimes use 128-bit blocks) and encrypts the data one block at a time. Stream ciphers encrypt the data as a stream of bits, one ...
