Hehe. Technically it doesn't work that way. At this very
moment, the certificate can be both valid and invalid.
However, once we query John about his state (akin to opening
the bag and checking up on the Cat) and he produces an
answer, the wave function that is John's SSL Certificate has
collapsed. At that point, the certificate can either be
valid or invalid, but not both.
Actually it can be both. Unlike in the real world of physics, the unreal
world of the Internet has morphed perceptions. And since in the real world
dualities cannot exist, this must be quantified. Which is the reason the
engine should not just check if the certificate is valid, but should also
check if it is invalid. If so, it must then be rejected.

What's more, you deserve to be hacked.
