Actually, yes. The crypto guys can make their codes arbitrarily secure
simply by making the keys arbitrarily long. With QC, the length of the
keys would make them a pain in the ass, of course. Even if we continue
Moore's Law-ing for the foreseeable future, given longer keys, computers
will not be able to overpower the algorithm found in PGP. spike
