Here we get four strings of 0 and 1.

Must be some xor magic. Simply try to xor all them together :

import binascii

one=int('0b0010001000101110001101110010100100111100001110000010111100001100001110000000011000001111001100000000000100011001001110010000100100100101',2)
two=int('0b0100000101000010010000110100010001000101010001100100011101001000010010010100101001001011010011000100110101001110010011110101000001010001',2)
three=int('0b0101000101011010010100110100010101000100010100100100011001010100010001110101100101001000010101010100101001001001010010110100111101001100',2)

xorlolz=one^two^three^four
print binascii.unhexlify('%x' % xorlolz)
