    CTFlearn plays with its words... carefully read the QUESTION

  • Fl4Gg3R

    I have tried a few arithmetic and bitwise operations but none of them seem to work?

  • Fl4Gg3R

    Finally solved it. I forgot about a certain operation.

    Read the comments below EVERY challenge if u have a problem. :)

  • ScipioPublius

    Dude I used the XOR calc. and entered the c0de, nothing...Try hacking harder. What do?

    • cdblish3

      make sure you read all the instructions

    • cdblish3

      make sure you read all the instructions

    • cdblish3

      make sure you read all the instructions

    • PanAdamski

      Now I understand.... I read recommendation again

  • _Z3R0_

    Read the description carefully. (ROX=XOR) Use the XOR calc: http://www.xor.pw/#

    cool next challenge (now remember and use);); all you need is a Roxy calculator and the ability to read letters and numbers

  • Iyxan23

    Not bad, pretty easy (after looking down the comments)

  • blackghost

    Interesting (reading the paragraph makes it easy at the end to solve the flag)

  • kuroneko

    well if you confused just use this link http://xor.pw/#

  • goniecki67

    Hard to find the right tool to do this since many tools don't support hex.

  • V1L3N

    guys the flag does contain CTFlearn{...} , don't get confused!

  • touCan

    As a noob, I had to read the comments to figure out the back story behind the hacker's name. Again, this forced me to research and learn what XOR is, which is exactly why I'm doing these puzzles.
