Cryptanalyse

Hi, i’m stuck in this level. I really haven’t no idea for this challenge.

I must draw a lot of pixel and finally it’s an image ?

I do a program for this ?

Thanks all for your answer.

Yes, you’re totally right :)
First, you have to understand the meaning of the given text. Then, I think that it’s easier to solve it with a script

Ok thanks
i try it now  🤑
