Hi,
I’m looking for an instant messaging ( IM ) apps software/protocol that run on Android and computer
and meet the following requirements :
- Open source !
- E2EE
- Messages are send in direct ! (not passing by a server)
- handle group
- Truly private ! ( That’s the tricky part )
The closest that I’ve found is Briar
- +can work without internet ! (bluetooth, local wifi, files !)
- + use TOR
- - Mutual party have to exchange key (or your can introduce someone)
- - sending media suck for now, poor image quality
- - no call or voice messaging
I’ve been looking for alternatives:
Session- Sadly it keep ALL the conversation into server !!! so it’s a no go.
- speek
- I didn’t try it yet, any feedback ?
- simplex
- it look very promising ! (didn’t tried it yet)
- + seem to handle multiple profile in one !
- + do not require that both party send an invitation !
- and have also a optional long term address
- ! I didn’t found (yet) if the messages are send in direct or pass by a server…
All post about alternatives or experience with the one that I cited are welcome.
The “truly private” req really smells with “I have no threat model and don’t know what am I doing”
Yeah. What does privacy mean?
Does it mean nobody knows what you’re saying? Doesn’t mean nobody knows that you’re talking? Doesn’t mean nobody can tell two people have engaged in a conversation?
In addition to direct observations, you can make indirect inferences from many of those characteristics.
If I can observe your peer to peer traffic I know who’s talking to who.
If I can observe your network, onion routing layer, I can determine who is talking to who with high probability
If I can see network traffic at all, I can determine who our members of a group, if the group messages are delivered simultaneously.
theres also notification scandal recently which i think the op doesnt know about
