Web29 jul. 2024 · AES is also characterized as a block cipher. In this type of cipher, the information to be encrypted (known as plaintext) is divided into sections called blocks. AES uses a 128-bit block size, in which data is divided into a four-by-four array containing 16 bytes. Since there are eight bits per byte, the total in each block is 128 bits. WebThere are two types of cipher algorithms: Symmetric With a symmetric or secretkey Encryption and decryption both use the same key. Standard (AES) is an example of a symmetric key algorithm. There are two types of symmetric key algorithms: Block cipher In a block cipher, the cipher algorithm works on a fixed-size block of data. For example,
