"WebRC5 is a parameterized, word-oriented algorithm. This means it is a block cipher with a two-word input (plaintext) and a two-word output (ciphertext) block size. The parameters are detailed as follows: Word size: w w w. This is the word size in bits. RC5 has two w w w bit blocks, so the input and output blocks are each 2 w 2w 2 w bits long.
