Only if you want a secure key. For SSH fuzzy fingerprinting the limiting
factor is the hashing, not the rate at which you can crank out keys, as long
as you don't mind that the keys aren't very secure. OK, they're not secure at
all, but that doesn't matter since you're going for spoofing, not a secure
signature forgery.
