RC4 is an example of a stream cipher (see RC4). Contrast with block cipher. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.

Block ciphers can also be used as stream ciphers when working in the CFB or OFB modes. Figure 2.7: Stream cipher. Stream ciphers are usually categorized as synchronous or self-synchronizing.

The size of the output of the algorithm is always a multiple of the block size. The RC2 key size can range from 8 to 256 bits. A proprietary algorithm developed by RSA Data Security, Inc., RC4 is a ...
