Weird Text (misc100)
Description: Giv m th flg plz !
Part of the supplied file was:
______

{

}
And it looked like it could be flag{STUFF_HERE}
So if you guess that “______ ____________ _ _______” was flag.
It’s easy to know the obfuscation used.
6 = f
12= l
1 = a
7 = g
It’s obvious it’s using charset of abcdefghijklmnopqrstuvwxyz
So i wrote a little script to parse it and give the solution.
misc100.py
Although doing it by hand would have been feasible too, it’s not long.
flag{g1v3-m3-th4-flag}
Your opinion matters!
