Which kind of invalidates the whole "public key" concept, doesn't it?
Not wanting to start a new discussion about this, but the fact that
(some) debian-created keys were weak (and thus crackable) wasn't the
servers fault, but the fault of the client that generated the key in
the first place (unless I'm getting something seriously wrong).
It's worse than that: the security of ElGamal encryption depends on
a strong random number to be generated for every message, not just when
the public key is first generated.
