comment What is pre-image resistance, and how can the lack thereof be exploited?
@PaĆ­loEbermann: Perhaps -- realistically, talking about which is more devastating is a little like arguing about whether it's worse to die by guillotine or firing squad. Either way you're dead (in a hurry). Just to be a bit more clear, I'll edit it anyway.

comment Why do we need special key-wrap algorithms?
It's probably worth noting that one of the conclusions from the paper is that although they think the algorithms they analyzed are probably at least reasonably correct, they could not prove any of them, and most of them are sufficiently complex (and some contain unexplained bits and pieces) that such a proof may well be impossible.

comment Is Blowfish strong enough for VPN encryption?
Being fair, DES was at least as much a product of IBM as of any federal bureaucracy (if anything, much more so).
