for i in reversed(range(16)): # At this point we know A_i (= state). We need to find the byte c[i] # and the previous accumulator A_i-1. # The relation is: # state = rol64(prev,5) ^ (c * M) # => rol64(prev,5) = state ^ (c * M) # Since rol64 is bijective we can invert it: # prev = ror64(state ^ (c * M),5) # We just need to find the unique c (0..255) that makes the next iteration # consistent. Because the algorithm is linear, *any* c yields a valid prev, # but only one will lead to a final accumulator of zero after 16 steps. # The easiest way: brute‑force the 256 possibilities for this byte, keep the # candidate that makes the accumulator after processing *all* remaining bytes # equal to zero. Since we go backwards, the first candidate we find is the # correct one. dosprn crack
