TextSecure VS session-android

Moxie's reasons for disallowing Signal distribution via F-droid always rang a little flat to me ( https://github.com/signalapp/Signal-Android/issues/127 ). Lots of chatter about the supposedly superior security model of Google Play Store, and as a result fewer eyes independently building and testing the Signal code base. Everyone is entitled to their opinions, but independent and reproducible builds seem like a net positive for everyone. Always struggled to understand releasing code as open source without taking advantage of the community's willingness to build and test. Looking at it in a new light after the XZ backdoor, and Jia Tan's interactions with other FOSS folk.

Signal has documentation on how to reproduce their Play Store builds and compare them with what you've installed locally:

There's nothing on Signal blog as of yet, but Signal's git repository was tagged with v7.0.0 yesterday and we can see from the commit history since the previously tagged version (v6.74.4) that there will be a setting to hide one's phone number [1], as well as disabling the previous default behavior of advertising that one is on Signal to all their contacts already using it [2].

Signal works the same but without the user tracking from Meta/Facebook. Many people use it as well but I'm surprised that a majority sticks to WhatsApp.

Telegram and Signal solve this.

Sadly yes: Looks like an open issue 13290 for Signal, sounds like they were/are indeed still interacting through google's push notification service, wat, and per a link at that issue it was a chore for Tutanota to break away once they realised it was a problem some years ago (though at least they thought about it years ago? wtf Signal...)

Here is one: https://github.com/signalapp/Signal-Android/tree/main/reprod...

Rule 1: Posts to r/signal must relate to Signal.

Other alternatives include Session (free) and Threema (paid - 5€).

Test it by downloading session at getsession.org and DM the bot by starting a new message and sending it to “Simple” (without quotes)

Figured there should be moves to set one up if not - https://getsession.org/

* marketing "Perfect Forward Secrecy" AKA "Forward Secrecy"[0].

I favor Session Private Messenger[1] because it is decentralized and allows third party clients, but Signal enthusiasts warn me that the Session client may, hypothetically, at some future date, integrate a cryptocurrency, as the Signal client already does[2].

If you have a mobile phone number, the domestic intelligence agency knows exactly where you are at all times and any LEO (without a warrant) can also find you. In addition, there have been numerous CCC presentations showing how insecure the global (excluding US) and (separately) US carriers are guilty of promiscuous metadata trafficking ($$) and insecure SS7 setups. As a consequence, for low $, you can go to any one of several shady websites and find the last location of almost any phone number (person unique ID) globally. There are additional varying exploitable vulnerabilities depending on the exact combination of {handset x carrier x country} to impersonate them, tap their line, reveal their exact location, and redirect their phone number through a third-party handset or even a PBX. These are more expensive and some capabilities are forbidden for all but a few selective intelligence uses.

Session (Signal fork) doesn't use phone numbers. It's pretty well-designed overall and uses an onion routing approach. It's already a superset of Signal except it doesn't use phone numbers. https://getsession.org

PS: Using regular TOR on home broadband or cloud servers is relatively risky and inefficient. Sybil attacks on it are common. And to network operators and security agencies it gives an easy "flow tag" of your uplink and exit node data traffic as automatically suspicious.
