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.

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.

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 ...
