there's also many of the services on the internet which seem to
offer free sip or xmpp server for voip, so guessing jitsi users can
Yes, you can use all XMPP&SIP servers with jitsi.
what if there's a bad server, would it for instance be technically
feasible for a server to eavesdrop on the conversation between 2
users with jitsi? or would the worst case possible be for the
server to capture encrypted traffic only which cannot be decrypted
and eavesdrop on
for text-messages: as long as you enable OTR encryption (padlock in
the chatwindow) AND!!! compare fingerprints with your partner over a
safe channel (best would be to meet in person) the server could just
record encrypted messages and wait untill quantum computers are ready.
For jingle (voice/video): enable zrtp (the padlock-thingy, should do
that on its own) AND!! compare the letters/numbers and you are safe.
jingle is allways out of band (i.e. the data is routed as direct as
possible between you and your partner and (if possible) does not ever
touch the server) but if the server is manipulative it could make you
route your data over the server.
If you do not compare fingerprints/numbers&letters man in the middle
attacks would be possible.
