the pieces)
Hi Aymeric,
By design, the answer is no. I'd either be leaking key material
(directly or indirectly), or leaking metadata.
Not sure, the problematic is: you have some keys, you receive some
encrypted packets, you MIGHT detect a pattern inside them that MIGHT
indicate you that the packet knows one of your keys, the attacker can
not do the same without knowing your keys, how to do this without
spectacular computation, I don't know, that's why I am raising this here.
Maybe this does not exist at all, would be surprising...
