Hi,

I had the impression that the news key naming convention would allow for 
"unique" identification of a machine. Thus it allows a machine to change 
its IP adress and still be able to communicate with its server. I though 
it would also allows to detect when a machine changes its keys, and thus 
refuse the news pair of key.

Based on these assumption, we built a system where we eagerly accept all 
keys from clients, and create their promise folders once they've been 
confirmed by a human. But when we remove the keys a client and 
regenerate new ones, the client is still accepted (as a new one actually)

Is there a way to prevent the connexion from a known node if its key 
changed, while still accepting connexions from unknown nodes ?

Regards
