WebFor each input block, the compression function is evaluated, with as input the current running state, and the input block; the output of the function is the new running state. The running state after processing the last block is the hash output. So now, the length-extension attack. Suppose that you give me a hash value h, computed over a ... WebNow you can use length extension to find the hash of a longer string that Simply run: x = "Good advice" h.update(x) print(h.hexdigest()) to execute the compression function over xand output the resulting hash. Verify that it equals the MD5 hash of m.encode("utf-8") + padding(len(m)*8) + x.encode("utf-8").
