No PIE means addresses are fixed – good for static analysis.

We have: (input_byte ^ 0x42) + 0x13 = c So: input_byte ^ 0x42 = c - 0x13 input_byte = (c - 0x13) ^ 0x42 target_rev = "dekarc_demongysoihp_138"[::-1] # wait, no: reversed target is correct # Actually easier: just reverse the known output first known = "831_physiognomy_cracked" rev_known = known[::-1] # "dekarc_demongysoihp_138" flag_chars = [] for ch in rev_known: c = ord(ch) original = (c - 0x13) ^ 0x42 flag_chars.append(chr(original)) Crack Digital Physiognomy 1 831

Run it:

flag = ''.join(flag_chars) print(flag)

Let target = "831_physiognomy_cracked" . No PIE means addresses are fixed – good
