comment Advantages and disadvantages of Stream versus Block Ciphers
D.W. is correct: The word 'Stream' in Stream Cipher reflects that there is a keystream - a stream of bits that is combined with plaintext to produce the ciphertext. It does not not reflect the plaintext composition. Obviously this is a detail that often confuses developers and engineers with whom the latter is usually implied. Block ciphers can be used to manipulate streaming plaintext just fine. Also often confusing is that Block Ciphers can be used as a Stream Cipher with an appropriate mode of operation and when the block size is atomic (e.g. 1 byte).
