It's a tough one if you don't know where to start. A hint is to think about what text some flags tend to start with or include, like { and } Visit ascii.cl and find that letters have ascii numerical values Mess around with python idle, try XORing some ascii values and see if you can get them to match the ciphertext in the challenge Google what the inverse of XOR is, its helpful in decrypting the message

im sorry but im extremly new to this stuff, this seems to be too hard any ideas of what i should be doing

q{vpl becomes flag{ ; See if you can figure out how each character was changed by comparing the character's encoded and decoded counterpart on ascii.cl ; HINT: the characters ascii value is XORed by a certain number.

! /usr/bin/env python3

A = "q{vpln'bH_varHuebcrqxetrHOXEj"

flag = [] for i in range(256) : for j in range(29) : flag.append(ord(A[j]) ^ i) [print(chr(k),end='') for k in flag]

flag.clear()
print('')
