    The "CTFlearn{...}" should perhaps be changed to "flag{...}"

      If it looks like a flag, but it says it's incorrect, then you might look for another one. The tester is usually right.

    For u guys who did not get the flag, it is: FLAG[Y0U_hAVE_BRUTEFORCE_xor]

    Though if ur reading this then you already got it xD!

  • musaku

    Good challenge. Pretty easy though if you just google the correct cypher.

  • Aster

    i found the flag but i cant seem to submit it. the format is confusing. i tried the standard and some but nothing worked

  • olelek

    //IN C++:

    include <iostream>

    using namespace std; int main(int argc, char** argv) { string ciph = "q{vpln'bH_varHuebcrqxetrHOXEj"; string outs = "q{vpln'bH_varHuebcrqxetrHOXEj"; for(int i=0;i<256;++i){ for(int k=0;k<29;++k){ outs[k] = ciph[k] ^ i; } cout<<outs<<"\n"; <br /> } <br /> return 0; }

  • Sumafix

  • LostGhost1

    Why does FLAG[YUhAVEBRUTEFORCExor] not work? How far am I from the correct answer?

    • LostGhost1

      Well, turns out there was the ACTUAL flag right beside this one. Seems confusing to have two potential flags like that eh?

    ! /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('')
