In cryptography, RC5 is a symmetric-key block cipher notable for its simplicity. Designed by Ronald Rivest in 1994, According to Ron Rivest, RC stands for "Ron's Code" but its documentation gives only RC5 as its name. The Advanced Encryption Standard (AES) candidate RC6 was based on RC5.
==Description== Unlike many schemes, RC5 has a variable block size (32, 64 or 128 bits), key size (0 to 2040 bits), and number of rounds (0 to 255). The original suggested choice of parameters were a block size of 64 bits, a 128-bit key, and 12 rounds.
