There are literally hundreds of messaging apps but the most popular among them is Whatsapp which has been installed on billions of devices with a great and positive response. Recently Whatsapp released it’s update which provides it’s user a 100% security i.e Whatsapp End to End Encryption.
What Does This End to End Encryption Means?
In simple and short words, no one other than you and the person you are chatting with can read or listen to your messages, your calls too are 100% private. Not even government can have access to them as all the messages will be locked and only you and your contact have the key (access) to those messages. This might create some problem in the countries where this encryption is not allowed according to IT laws.
Every message has a unique lock on it, for example, suppose you send a message “Hello” then in the Whatsapp database it won’t be stored as “Hello”, it won’t be plain text form rather it would be like “!@^%#” which is not readable, not even Whatsapp company would be able to decrypt these messages as they do not hold the key to it, which means your privacy is literally all yours now.
How to Enable Encryption on Whatsapp?
Unlike other chatting apps like Hike or Telegram there is no need to enable the private mode manually for every single chat, if you and your contacts have the latest whatsapp version installed on their devices then this will get activated automatically.
As soon as you both update whatsapp, you will see a message “Messages you send to this chat and calls are now secured with end-to-end encryption. Tap for more info.”
How to Verify Encryption?
Now you need to verify if the encryption is enabled with a particular contact or not. First of all if you see the message “Messages you send to this chat and calls are now secured with end-to-end encryption. Tap for more info.” then it means that encryption has been enabled but there are 3 ways you can perform the check:
1.) Open any contact in Whatsapp and tap on the name of that contact to check out their status/DP. There you might see a message with a green lock “Messages you send to this chat and calls are now secured with end-to-end encryption. Tap for more info.”, the green lock and this message tells that the encryption has been enabled.
2.) Tap on this message withing the chat and you’ll see a bar code with some digits below this, ask your contact to send you the screenshot of those digits which are displayed on their device and match all those digits with the digits which are being shown on your device, if they match then the encryption is enabled.
These digits are different for all of your contacts.
3.) Scanning the code: Just below those digits you will see a button “Scan”, tap on this button if the other phone (your contact’s phone) is with you, scan the code and if it shows the green signal then you’e good to go.
Although some users have reported seeing the red alert even they had everything correct, this might be bug which may see a fix in upcoming updates.
