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?

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'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.
