Extract the flag from the Gandalf.jpg file. You may need to write a quick script to solve this.

I really don't understand. I decoded the 2 b64 strings then I tried xoring the first one with the second string but I don't get the expected result. I get something like "tln{ndalfBibBagis"... Which is close to Gandalf Is Big or something like that...

You are close... the flag starts with CTFLearn{... xoring is the correct thing to do after you convert the b64 strings to raw bytes

why raw bytes
