Secret key K of size b bytes is used to initialize array L consisting of c words where c = b/u, u = w/8 and w = word size used for that particular instance of RC5. The input/output blocks are 2w = 64 bits long, just as in DES. Duke Nukem: Total Meltdown Review, At one point, RSA, which owns the patent for RC5, was so sure of its security that it had a bounty system to reward anyone who could break items encrypted with the algorithm. Kaliski and Yin estimated the strength of RC5 by differential and linear cryptanalysis. A regular expression is a method for specifying a set of strings.
