I'm a little worried by the assumption here that adding the key size
check is sufficient. It's certainly an improvement, but key ID
collisions are clearly possible even without this - they're just more
work. The key ID isn't *that* long, and it is still many orders of
magnitude easier to construct an attack that involves a key ID collision
than to brute-force the key itself. Can somebody explain to me how this
approach defends against such an attack?
