djb is getting better at trolling ;)
from TFA: "2^128 security even against attackers equipped
with quantum computers".
wouldn't bet much money on this.
first, it is not known if P=NP (someone wrongly claimed in
this case "everyone will be composer". certainly
sufficiently high degree algorithm won't help at all).
second, it is not known even if P ≠ NP, can a sufficiently
powerful quantum computer solve SAT efficiently? -- if the
answer is ``yes'' djb & co fail.
not to mention that if djb is using "qmail + csh",
"Shock-See-Shell" will screw him beyond crypto.
