Am I ok? #1 (crypto challenge series)

I’ll be posting random challenges as I learn new stuff. It will be using the basic concepts of crypto, but since even this can be hard to get right, don’t take my word for granted regarding anything I say here.

This is the first (and hopefully not the last) in series “Am I ok?” where we define some concept and you get to tell whether the document is sound or not.

Have a read.

Unfortunately, I don’t have money to give away for correct answers so you only get paid by minutes/hours of fun - so make the most out of it!
