WebFeb 1, 2024 · A 64-bit cipher key is used to produce five distinct keys in the key generation section where a 64-bit input is partitioned into four blocks, each holding 16-bit data, after initial permutation. Each of the four blocks provides input to the F-function. A 4 × 4 matrix is used to translate the output of the F-function.
