Webstream cipher: A stream cipher is a method of encrypting text (to produce ciphertext ) in which a cryptographic key and algorithm are applied to each binary digit in a data stream, one bit at a time. This method is not much used in modern cryptography. The main alternative method is the block cipher in which a key and algorithm are applied to ...
