But Light is like a generic incarnation of god but also knowledge, revelation etc., it’s way more absolute than peace or even love. I think Light does make sense from their perspective, and in the catholic symbolism it is identified basically with all positive stuff.

You had a bunch of other references that make sense eh, I am not familiar with them, so I respect that people might have different perceptions.

Uh?

I know nothing about anime, but I guess it is not that bad? Luce is straight up “light” in Italian, and Lucifer just means “the one who brings light” because it’s the Angel’s name, before the fall according to the fairytale. So from their POV it should all make sense.

Many encryption algorithms rely on the assumption that the factorizations of numbers in prime numbers has an exponential cost and not a polynomial cost (I.e. is a NP problem and not P, and we don’t know if P != NP although many would bet on it). Whether there are infinite prime numbers or not is really irrelevant in the context you are mentioning, because encryption relies on factorizing finite numbers of relatively fixed sizes.

The problem is that for big numbers like n=p*q (where p and q are both prime) it’s expensive to recover p and q given n.

Note that actually more modern ciphers don’t rely on this (like elliptic curve crypto).
