WebAug 3, 2024 · AES-128 encrypts blocks of a 128-bit size. AES-192 encrypts blocks of a 192-bit size. AES-256 encrypts blocks of a 256-bit size. In addition to having different block sizes, each encryption method has a different number of rounds. These rounds are the processes of changing a plaintext piece of data into encrypted data or ciphered text.
