What is Signal? The messaging app, explained.

But the signal uses other technologies to keep your messages, especially and safe as well. For example, he is doing his best to make it difficult for the same sign servant to know who you are talking to (a feature known as the “deceptive sender”), or for a striker who records traffic between phones to decode traffic later by seizing one of the phones (“ideal secure”).

These are only a few of the many safety features included in the protocol, which is well designed and flowing for other messaging applications, such as WhatsApp messages and Google, to use the same messages.

The signal is also designed, so we do not have to trust the people they make. The source code for the application is available online, and because of its popularity as a safety tool, it is frequently reviewed by experts.

Although its security does not depend on our confidence in the publisher, it comes from a respectable source: the indication technology institution, which is a non -profit institution whose mission is to “protect freedom of expression and empower safe global communication through open source privacy technology.” The same application, and the institution, originated from a community of prominent privacy defenders. The foundation started by Moxie Marlinspike, a long -standing encryption photographer for safe private communications, Brian Acton, founder of WhatsApp.

Why do people use other text applications? Are others safe?

Several applications offer an encoder from running to the end, and it is not a bad thing to use for a privacy scale. But the sign is a golden standard for private call because it is a default safe: unless you add someone you do not mean, it is very difficult to make the chatting mistakenly less safe than you mean.

This is not necessarily the case for other applications. For example, IMessage conversations are sometimes encrypted, but only if your chat contains “blue bubbles”, and is not encrypted in iCloud backup. Google messages are sometimes encrypted from end to end, but only if the chat shows an icon of lock. WhatsApp is encrypted from one side to the tip but it records your activity, including “how you interact with others using our services.”

The indication is keen not to register with him, to provide ways to reliably delete messages, and to keep messages safe even in backup via the Internet. This focus shows the benefits of the application coming from a non -profit institution that focuses on privacy instead of the company that sees security as a “good to have” advantage in addition to other goals.

(On the contrary, as a warning, using the sign makes it easier to lose messages by mistake! Again, not a good choice if you are legally required to register your connection.)
