comment Understanding a Blowfish cryptanalysis
Writing it down helped a lot actually. It became much clearer, and I now understand where the equation comes from, and why it looks as it does, which was my question. It will suffice for now, so many a hat off to you, and thanks once again!

comment Understanding a Blowfish cryptanalysis
Hmm, ok. It did get a bit messy at toward the end. I'll give it a shot with paper and pen, to see if I can clear things up a bit. But it's not improbable that this is way above me; I haven't spent too much time studying differential cryptanalysis.. But I will most certainly take your advice and read up on the subject. Thank you very much!

I got it from an article. Will add link!

@CodesInChaos: Thank you, I'll take a look at that!

comment Is it safer to encrypt twice with RSA?
The exercise did not require any previous knowledge, so assuming textbook RSA is probably sufficient :) @mikeazo : Thanks a lot, I do see why it's not safer now. In fact it is very obvious, now that I read it. And no, I don't have any more brute force options in mine :) Thank you!

@StephenTouset: This is a theoretical problem, not a practical. Therefore the option to choose a longer key is irrelevant, but thanks for the input.

I do follow your arguments, and I agree with them. Although, I was looking for a more mathematical explanation. I've added some info to the question to make it clearer.
