What is Signal App & How does it work?

The instant and secure messaging app is a signal that was built on the current textsecure and RedPhone apps. This app was built in march 2015 by the open whisper systems. This app is available for android and iOS users to free of cost and maintains interest only from donations and contributions.

The signal app allows to send of encrypted calls and text and it can be performed from anywhere across the globe. The signal app has encrypted messaging that is guarded by end-to-end encryption.

What is the importance of a secure messenger?

Most of the instant messaging apps in the market are using end-to-end encryption. This encryption process includes a server, the sender’s device, and the recipient’s device. The message is sent from the sender’s device through a server to the recipient device and in this duration, the message is in encrypted form on the server. Without having encryption, when the sender sends any message until received by the recipient, the message can be read by anyone and become treated as plain text. To convert the plain text into cyphertext or encrypted you need end-to-end encryption in your app.

The meaning of end-to-end encryption is there is encryption codes are collected at both ends for instance on the user’s device same is on the server so no one can read the message except the recipient and sender, not even the service provider can understand the message. For hacking these encrypted messages, a hacker has to access the user’s tools and the service provider server that is not easy.
