Actually Signal was suggested by a friend in one of my former chatgroups, so I am at the moment split between telegram and signal for different groups. I do like signal and the feel of it. Will try out videochat in both apps further on.
Signal & Mathematical backdoors in encryption algorithms
Govt funds Signal (NOT for protestors, Journalists, or the like) & others https://yasha.substack.com/p/spy-funded-privacy-tools-like-signal Yeah, that’s pretty troubling. Like Tor, Signal might work if you’re chatting with your local neighborhood dealer to score a few grams of coke, but don’t expect it to protect you if you decide to do anything really transgressive — like organizing against concentrated corporate political power in the United States. For what it’s worth, I personally heard activists protesting the Democratic National Convention in Philadelphia tell me that the cops seemed to know their every move, despite the fact they were using Signal to organize. https://surveillancevalley.com/blog/internet-privacy-funded-by-spies-cia
Why Isn’t Telegram End-to-End Encrypted by Default? https://telegra.ph/Why-Isnt-Telegram-End-to-End-Encrypted-by-Default-02-23 To protect the data that is not covered by end-to-end encryption, Telegram uses a distributed infrastructure. Cloud chat data is stored in multiple data centers around the globe that are controlled by different legal entities spread across different jurisdictions. The relevant decryption keys are split into parts and are never kept in the same place as the data they protect. As a result, several court orders from different jurisdictions are required to force us to give up any data. Thanks to this structure, we can ensure that no single government or block of like-minded countries can intrude on people’s privacy and freedom of expression. Telegram can be forced to give up data only if an issue is grave and universal enough to pass the scrutiny of several different legal systems around the world. To this day, we have disclosed 0 bytes of user data to third parties, including governments.
You may want to reevaluate why Telegram makes it’s own encryption. And why Telegram maybe the better option.
