RC2 is a block cipher that encrypts data in blocks of 64 bits. 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 ...

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 ...
