RC5 (Rivest Cipher 5) ist eine 1994 von Ronald Rivest entworfene symmetrische Blockverschlüsselung. RC5 makes use of 2 magic constants P and Q whose value is defined by the word size w. For any other word size, P and Q can be determined as: Here, Odd(x) is the odd integer nearest to x, e is the base of natural logarithms and is the golden ratio. Here we assume w = 32, although the formal speci cation of RC5 admits variants for other word lengths, such asw = 64 bits. and consumes less memory.
