Help me!!!

You don’t really need to replace anything to pass this level.
Focus on the level, the description, the picture, what’s inside the picture
–> You’ll find something important and you’ll understand what I’m talking about when you’ll find it

Then, read the hint and work a lot on it, without overthinking it too much
–> You’ll find another something important

At this moment, you’ll understand you need anotheranother something
–> Post there or PM me at this moment and you’ll have some help :)

Good luck & happy challenging!

Hi. First of all, thanks for the reply. My schedule freed up nicely this week so I figured I’d tackle this level again and, would you believe it, I have the same problems I did before :) . Now, I’ve found the url and some hints for the encryption algorithm used but I need the encryption key and I cannot seem to find it. Any hints would be greatly appreciated :D.

Try learning more about this algorithm and you’ll probably get what’s the main weakness of this cipher that will help you recovering the key ( and thus, get the actual answer )

Good luck!
