Web8 Sep 2024 · Block Ciphers. Unlike stream ciphers that are applied continuously bit by bit, block ciphers, like the name implies, are applied on a fixed-length bit block - which, for the example of AES, is 128 bits long. Block ciphers are deterministic algorithms - so, for a specific key and input data block, the resulting block will always be the same.
