padding oracle attack - how to represent hexadecimal as one byte in python

Question

I am trying to carry out a padding oracle attack. I am aware that I have to modify the bytes from 00 to the point where it succeeds, to find the correct padding. But, how do I represent 00-FF in python? When I try representing it as a part of the string, 00 is taken as 2 bytes.

PS - This is a homework problem.

Answer 1

执行'\\ x00 \\ x00 \\ xff'或“ 0000ff” .decode（'hex'）应该可以。
