What is End-to-End Encryption?

If you are looking for a system of communication where your data is not read or secretly modified by anyone, not even by your service provider, then you should opt for the most secure messaging app that offers End-to-End Encryption(E2EE).


In this form of the encryption standard, only the sender and the intended recipient users can access data or messages. The hackers or any third-party intruders can’t access data when it is in transit or at rest, not even from the servers.

What is Encrypted Messaging?

To encrypt a message, certain key-based encryption algorithms, such as symmetric and asymmetric, must be applied to secure the contents of the message from a hacker while only allowing the sender and the intended recipient to read it. 

Your personal or business messages can attain the highest form of security and authenticity with a public key used for encryption and a private key for decryption.

Hence, it is advised to choose an instant messaging software that offers secure communication.
