I see, I think I understand it better now. Thanks!

Ah, certainly accepted, this is an excellently detailed answer :) I'm curious however. What about two (different) strings with "no entropy", hashed (separatedly) alongside a common string with 128 bits of entropy (and resulting in two 128-bit hashes). Will both have 128 bits of entropy, or 64 bits, or something else?

Ah, I see. Since I'm sure you're right I'll leave it at that.

I see, but if the amount of randomness involved was variable (and trully random), that wouldn't make all the numbers trully random (even if parts of them weren't)?

But what if you had a lot of pseudo-random numbers with just a bit of random numbers actually generated from something like static noise? if someone can't guess the random part, wouldn't that mean he/she would not be able to guess the whole thing either? I don't know much about the subject but just /dev/urandom seems pretty unbreakable by anything non-brute.
