Ancient crypto? You really have no effing clue, do you?Whatever you use today, it will be ancient in 5 years.PGP came out when? 1991. Will be a quarter century old in 5 years.
DES is the first example I can think of. Folks did believe in that. Pity it's crackable. Pity even more those who believed in it, then posted their passport encrypted with it, to a security list...
Amazingly enough, they're all pretty much still going strong - mostly
So you mean that some of them aren't going strong, then? Did they get cracked, by any chance? Did I mention DES yet?
because the crypto field moves pretty damned slowly. The general philosophy in crypto isn't "It will be ancient in 5 years", it's "we won't even trust it for live deployment until good people have bashed it for a decade".
Good people will find flaws. However they cannot stop brute-forcing, which is viable in some circumstances, and as time passes this viability increases. This increase is not the same as Moore's Law, if you have a parallel platform you are not limited by linear growth in CPU power, you just add more CPUs. As it happens parallel platforms are great for brute-forcing, did I mention DES, which was cracked by a machine with 1856 processors?
Even if nobody finds a weakness in the algorithm you used, 5 years from now I will probably have enough spare CPU to brute-force it using my mobile phone....Moore's Law doesn't move *that* fast.
I was joking (but only half-joking).
And what good drugs are you on that you think a cell phone processor 5 years from now will have the CPU power that current moby-cluster supercomputers have?
I'm not saying that, I'm saying that in 5 years, the currently infeasible will be feasible. No, I don't think that's a surprise either, but I don't think Tim has considered it.
