WebNov 14, 2024 · The AES algorithm is an iterative, symmetric-key block cipher that supports cryptographic keys (secret keys) of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits.The below figure shows the high-level AES algorithm: If the data to be encrypted doesn't meet the block size requirement of 128 bits, it must be padded. WebThanks to this exploration of the Caesar Cipher, we now understand the three key aspects of data encryption: Encryption: scrambling the data according to a secret key (in this case, the alphabet shift). Decryption: recovering the original data from scrambled data by using the secret key. Code cracking: uncovering the original data without ...
