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 ...

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 ...
