An encrypted communication between zabbix-server and agent would be great.

I understand that I could use external tunneling (ssh, stunnel ), but it is not so straightforward solution. Builtint support would be far better.

Thx

edit (richlv) : encryption should be supported by all components :

server (also node-node);
proxy
agent
zabbix_get
zabbix_sender
java proxy

note that this issue only deals with pre-shared key support. additional issues :

ZBXNEXT-1263 - ssl
ZBXNEXT-1264 - kerberos
