Trying to get the hijacked thread back on track, are you? We'll see about that.

Logic would tell me yes - but I a guessing this is some sort of trick question. All I can say is how can you get anything other than random when you start with random. This has all the earmarks of a gotcha, so bring it on.

I don't know what the mathematical answer is, but if the practical answer isn't YES, then NSA's in a heap of trouble. Summing (XORing) pseudo-random strings is pretty much the basis of a lot of encryption strings. Actually, in encryption, only one of the strings needs to be random.
