Going back to a year, WhatsApp has been working on securing conversations and now, by partnering with Whisper Systems, WhatsApp has been able to achieve complete end-to-end secryption for all communications. With end-to-end encryption, text messages, pictures, videos and even voice calls sent in WhatsApp can’t be intercepted by 3rd parties. WhatsApp’s encryption is carried out by default unlike BBM Private Chat where you have to turn on when you wish.
WhatsApp’s end-to-end encryption is available when you and the people you message use the latest versions of our app. Many messaging apps only encrypt messages between you and them, but WhatsApp’s end-to-end encryption ensures only you and the person you’re communicating with can read what is sent, and nobody in between, not even WhatsApp. This is because your messages are secured with a lock, and only the recipient and you have the special key needed to unlock and read them. For added protection, every message you send has its own unique lock and key. All of this happens automatically: no need to turn on settings or set up special secret chats to secure your messages.
How to Check and Verify the Encryption Status on WhatsApp
If the encryption has been rolled out to you, you’ll see a lined text on the conversation screen about it, but if you don’t see anything, your conversation may not be secured. To check the communication security status, simply click on the receivers profile and check out the encryption if the padlock is green or not. If it green, your messages are encrypted using the end-to-end encryption, but if it’s not (padlock unlocked) your messages are not encrypted.
You can also verify your encryption by scanning the QR Code on any of the two devices which could either be yours or the recipient’s. You can also compare the numbers under the QR Code if they match. though the QR Code method is way faster. you see a green pass mark if it’s successful.
This encryption is not only limited to one platform as it is available on Android, iOS and also BB10. If you can see the encryption feature on your WhatsApp, you need to update to the latest version.
