Without an independent audit, we really have no choice but to trust the company when it says our messages are secure. The truth is, the best encryption protocols are studied, tested and generally (but not always) open source. Without this authentication method, you could conceivably be chatting with - or having your messages intercepted by - a third-party (called a man-in-the-middle attack).Īnother concern with the protocol is in the idea that some companies believe they can roll their own solution by understanding the basics of cryptography. Two other popular services, Signal and WhatsApp, allow you to compare key fingerprints with the other party, a feature Viber’s encryption method doesn’t seem to offer. While end-to-end encryption is a great idea in theory, the reality of the matter is that not all encryption is created qual. What’s not immediately clear is what protocol Viber is using to protect its users. The service will also offer a “hidden chat” feature that allows users to hide specific conversations from the home screen. We will continue to make this an ongoing priority as digital communication evolves.” Because of this, we have spent a long time working on this latest update to ensure that our users have the most sophisticated security available and maximum control over their communications.

“We take our users’ security and privacy very seriously, and it’s critical to us that they feel confident and protected when using Viber.

Once you download the newest update, Version 6.0, each voice and video call, text message, video and photo share in both private or group chat will be encrypted. Viber announced today that it’s rolling out end-to-end encryption on all platforms - Mac, PC, iOS and Android.
