Writeup

  1. We can simply create a python file to transfer ascii code to char.
     flag_enc = chr(0x39) + chr(0x63) + chr(0x34) + chr(0x32) + chr(0x61) + chr(0x34) + chr(0x35) + chr(0x64) 
     print('picoCTF{gl17ch_m3_n07_'+ flag_enc + '}')
    
  2. Here ‘s flag: picoCTF{gl17ch_m3_n07_9c42a45d} ٩(^ᴗ^)۶
