Encrypted messaging apps are applications that secure the content of messages through encryption, making it difficult for unauthorized users to access the information. These apps use complex algorithms to scramble messages, ensuring that only the intended recipient can read them. Popular examples include Signal, WhatsApp, and Telegram. The primary purpose of encrypted messaging apps is to protect user privacy and enhance security during communication. By using end-to-end encryption, even the service providers cannot read the messages exchanged between users. This feature is especially important for individuals concerned about surveillance or data breaches.
