&gt;You have to create the algorithm to reverse an arbitrary AES-256 key, which is considered to be impossible, so that doesn&#x27;t really make a difference.<p>What? Why is brute force impossible to code? I don&#x27;t understand what you&#x27;re claiming.<p>I agree that adding in Moore&#x27;s law doesn&#x27;t change the numbers by much. Moore&#x27;s law plus weakening of cryptographic assumptions might do it, though. Plenty of previously-believed-to-be-strong crypto algorithms have been cracked, it&#x27;s reasonable to think that we just don&#x27;t have the tools to create unbreakable codes yet. (E.g. RSA is known to be breakable with quantum computers with Shor&#x27;s algorithm.)
