After validating of my public XMPP service on xmpp.net, I've got the error:
Warning: Server offers no forward-secret ciphers. Grade capped to A-.
Is there an easy way to enable these ciphers? As title states, I have Debian Stable and ejabberd installed from its repository.
I've checked all the servers listed in https://xmpp.net/directory.php which have
ejabberd installed with its build date
2011/12/24. This is Debian Wheezy's ejabberd obviously. The top score of any of these servers is
A-/A-, so I believe it is really difficult to enable
PFS for this software.
