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.
