The result is ’a9a031cfddcb10d91c8e7b4926086f7e’.
6. Final stage:
The A1 result: The nonce from the proxy response is
‘11432d6bce58ddf02e3b5e1c77c010d2’.
The A2 result: The equation to be evaluated is
‘A1:11432d6bce58ddf02e3b5e1c77c010d2:A2’.
The MD5 algorithm is run on this equation. The outcome of the calculation is the
