How I'm now using Signal on UT

rdfrs

So I managed to set this up. Thanks for the info! That was really helpfull. But now I have no clue how to use the Signal bridge in Cinny. How do I use it to send/receive a message?

Moem

@rdfrs The easiest way is to send each contact a message through Signal or Signal Desktop and then they will appear in Cinny. You should see an invitation come in for each of them.

@rdfrs in addition to what @Moem explained, you can also go to the room with signal bridge bot, there you can type

help to get a full list of available commands
start-chat PHONENUMBER to start a chat from the bot end, provide the phone number in international format as +1234567890

And once you have your chats as rooms in Cinny, you can type messages there as with any other room.

@danfro @Moem thank for the help! Its works perfectly. Do you know if there is also a bridge for whatsapp ?

Read through the thread, I believe there is a post about that. I don't use it myself.

Hi @rdfrs

I don't use WhatsApp, but yes there is a bridge:

I followed Sander's instructions to bridge Whatsapp through beeper and being accesible through Cinny.
It does work but I can not read the whatsapp messages as says that are encrypted.
Anyone know how to solve?

@Moem Am I wrong to believe that this technique ruins end-to-end encryption and that the matrix server that acts as a relay ( here @signalbot:tchncs.de ) gets to access all your messages unencrypted?

Sander

@Marcos Did you follow the verification step?

Verify Cinny as a Matrix client. A red shield will appear in the left sidebar. Click it, choose Verify Manually, and enter the recovery key you saved when setting up your Beeper account.

It could take some time before all messages are decrypted after that. If they stay encrypted, you could also remove Whatsapp from Beeper and add your account again, now that Cinny is a verified client.

I'll be honest: I don't know! As far as I know it replaces the Signal encryption by Matrix encryption, so I guess it could, in theory, snoop? But I'm not an expert.
In any case, if you're worried about that it's probably better not to use this method.

@Moem

Well I'm not sure, but it seems like the signalbot server : tchncs.de is the one who connects to signal, and fetches messages, decrypts them, and then redirects them through matrix. So they get to have the possibility to see unencrypted messages, which voids a bit the utility of signal.

One interesting thing would be to be able to host the matrix bridge at home, or even on the phone itself, but seems a bit complicated.

If the encryption matters to you, then it does. I think you should only use a bridge if you feel you can trust the person who hosts it.

And yes, hosting it yourself is an option, but that's more work / a bit more complicated. A loss of convenience is often te price we pay for privacy / security.

I don't think it can be done on the phone. But I've never looked into it.

@Sander I removed and re-bridged whatsapp and messages are already decrypted so, it worked! Big thanks for the support
