This transparency makes many users opt for this application instead of its competitors, since for many people privacy is the real reason to use a messaging application, over and above its functionalities. And is that Signal offers many interesting functions that make it an application more than enough to meet the average needs of anyone. The key to its security does not lie as many people think of its end-to-end encryption , since applications like WhatsApp already implement it. What really makes Signal safe is its transparency for users, being open source and visible to anyone. In addition to privacy, security is a priority. For this, Signal uses its own communications protocol to encrypt your messages called Whispers Systems, which encrypts the sender’s message to later decrypt it at the receiver, preventing any interceptor from taking over the content. This protocol is so good that WhatsApp uses it for its application. Signal has received the highest rating from the EFF for secure messaging apps, along with secret telegram chats and other apps. It is also the application recommended by the European Commission. The application became known when Edward Snowden claims that it is the application he uses to chat with his contacts. And in the wake of Facebook, a growing crowd is increasingly concerned about security. Some messaging apps like WhatsApp are known to collect metadata , and have been leaked to Facebook on purpose, for example. Signal has been designed to end-to-end encrypt messages, but also all information that is stored locally. With Signal you can send text messages, images, audios, and files to your contacts, but it also has features that are widely used as groups or video calls, both individual and in groups.

It was created by security and robotics specialists Moxie Marlinspike and Stuart Anderson to initially launch as TextSecure in 2010, to finally be Signal in 2014. Signal is an instant messaging app focused mainly on user privacy and security. On this page I am going to show you the answer and how you can do it. If you are a user of this application, you may have asked if it is possible to install the Android app Signal for PC.
