Everything is fast-paced in today’s digitally-advancing time; from ordering food to texting someone, everything is just one-click or one-tap away. We all have integrated technology into almost every aspect of our daily lives, and mobile apps play a significant role in all these. Yes, technology has made lives super-fast and easy for people; but security is also of considerable concern for everyone.

No one wants their privacy to be invaded, especially when it comes to personal messages. People don’t want their conversations to get into the hands of cybercriminals, and other malicious programs focused on stealing them. It is estimated that a hacking attack takes place worldwide every 39 seconds. It is affecting one in three Americans each year.

It can be related to anything, from leaking personal information to private chats. That’s where end-to-end encryption comes into major play. If you’re looking for an instant messaging app solution that is well-secured, hiring a reliable app company is a smart move. They can help you build a well-encrypted messaging app that guarantees users’ conversations are safe and have no chance of anyone brute-forcing into their private chats.

What Is End-To-End Encrypted Messaging?

While sending a message to someone these days, we all tend to see a text appearing time and again, “Messages you send to this chat and calls are now secured with end-to-end encryption. Tap for more info.” Remember? What does that mean? What exactly is end-to-end encryption? Let’s find out!

End-to-end encrypted messaging means that the users within that specific chat can only read messages sent between two people. It is the process of encrypting senders’ messages that can be decrypted on the recipients’ devices only. When end-to-end encrypted, all the messages, media, documents, everything is secured from falling into the wrong hands.
