Security Verification WhatsApp End-to-End Encryption.

WhatsApp has released an end-to-end encryption security feature, marking the biggest change in WhatsApp history. Now, all information sent via WhatsApp will be secured with 256-bit code encryption. This means that only you and your friend, to whom you are sending the message, can see the content. Third parties, including hackers, cybercriminals, government agencies, and even WhatsApp itself, will not have access to your messages, calls, videos, photos, documents, etc. However, to ensure this security, you need to check and verify your end-to-end encryption with your friends.

How to Check End-to-End Encryption Security in WhatsApp?

Open WhatsApp on your smartphone, Choose the friend’s contact or group with which you want to check encryption security.

When you will open the contact or group chat screen a message will appear on the chat screen with a lock icon. This message will be something like this.

WhatsApp-Encryption-message

“Messages you send to this chat and calls are now secured with end-to-end encryption. Tap for more info.”

When you tap on the message, you will get more information related to encryption:

“Messages you send to this chat and calls are now secured with end-to-end encryption. Which means WhatsApp and third parties can’t read or listen to them.”

If you see above message your connection is encrypted with your friend or with group chat. Sometimes if your friend has not updated their WhatsApp or he/she is using a different version of WhatsApp than yours. Then You will see the message in View contact/group info page, something like this:

Non-encryption-message

“Messages you send to this chat and calls are not end-to-end encrypted. Tap for more info.”

And when you tap on the message then you will get correct information why the connection is not secure or not encrypted:

“Messages you send to this chat and calls are not end-to-end encrypted because your “friend” needs to update WhatsApp.”

And also when your friend Switches their mobile number or reinstall the WhatsApp then another message will appear on the chat screen:

“Your Friend’s security code changed, tap for more info.”

& When you tap on the message then you will get this info:
