WebRijndael is a block cipher. What this means is that messages are broken into blocks of a predetermined length, and each block is en-crypted independently of the others. Rijndael operates on blocks that are 128-bits in length. There are actually 3 variants of the Rijndael cipher, each of which uses a diﬀerent key length.

Say we send messages A and B of the same length, both encrypted using same key, K. The stream cipher produces a string of bits C (K) the same length as the messages. The encrypted versions of the messages then are: where xor is performed bit by bit. shannex health care
