Bytes of plaintext go into the stream cipher, and bytes of encrypted text come out the other end. RC4 is an example of a stream cipher (see RC4). Contrast with block cipher. THIS DEFINITION IS FOR ...

The RC2 key size can range from 8 to 256 bits. A proprietary algorithm developed by RSA Data Security, Inc., RC4 is a stream cipher. A stream cipher encrypts one byte at a time. The RC4 key size can ...

The RC4 Keystream Generator implements the RC4 stream cipher in compliance with the ARC4 specification. It produces the keystream that consists of 8-bit words using a key with the length up to 256 ...
