# Instead of a complicated generic reverse, we exploit the fact that # CRC‑32 with polynomial 0xEDB88320 is reversible byte‑by‑byte. # The following tiny routine does it: def reverse_crc_bytes(target, nbytes): crc = target out = [] for _ in range(nbytes): # The low byte of the CRC is the byte that was processed last, # after the forward step it becomes (crc ^ byte) & 0xFF. # So to reverse, we take the low byte as the original data byte. b = crc & 0xFF out.append(b) crc = (crc ^ TABLE[b]) >> 8 return list(reversed(out))
