Today's signal update, because they reportedly broke it. Information has appeared in various places, twitter and other nooks and crannies of the strange Internet. Anyway, every now and then they appear that Signal has been broken, compromised, etc.
Reassuringly, as of March 2022, nothing is known about any known threat or vulnerability of Signal. It continues to provide full communication privacy. I use it all the time, and recommend it because I value both privacy and am simply a fan of the application. Signal provides end to end encryption, meaning that any information is stored only on your phone, possibly your caller's phone, and transmitted only in a way that makes it impossible for anyone but you and your caller to read the content.
Remember that end-to-end encryption does not protect you if someone takes over your phone. Famous recent scandals. What fact of looking over your shoulder, if someone is here, you can have everything encrypted, he can see what you see. The Signal application is open source software. Its code is available to the public and is regularly reviewed by programmers, cryptography experts, also it's an interesting point, an interesting way of security and in my opinion it's just value.
Regarding the famous three-letter services, every organization is forced to cooperate with local authorities, and so Signal, at their request, releases all but all the information it has on its servers about its users. That is, virtually nothing. Contacts, messages, call histories are exclusively on your phones.
The same goes for a potential hack of Signal's servers. Even in the event that this happens, it will leak all the information that is there, which is none. Further Signal turns on all encryption options by default. Anyway, you can't even turn them off in this application, which is very cool, there is no other option.
In telegram, for example, you have to configure it additionally, and it is known that if you have to configure something additionally, most do not use it. Unless something has changed recently in telegram? Command can be treated the fact that it is used by journalists, politicians, activists, IT professionals. As for the names Elon Musk, Mark Zuckerberg, Edward Snowden, Whatsapp uses Signal protocol all the time.
As a curiosity, since February 2022 you can change your phone number, which previously you could not do, I mean you could do, you just lost your contact history, communication history, contacts. Yes, it just works that way. You can do it from February 2022 provided you have your old phone without it is impossible. In conclusion, I use!
