WebJan 14, 2011 · Data (the stuff to be encrypted) usually comes in streams. To encrypt it, we need to employ a stream cipher, that is, an encryption algorithm suitable for use on a stream of data. A stream is a sequence of bits (or bytes) of arbitrary, varying, or unspecified length. The best ciphers we have invented so far are usually block ciphers.
