Why WhatsApp chat leak even after end to end encrypted – Explained

Hello Users, hope you are doing well. Today we talk about WhatsApp’s end to end Encryption, it’s working and possible leak options, and available options for a secure chat. As we all know WhatsApp offers an end-to-end encryption service on its chat platform. We as a user always believe that our chats are encrypted but recently many news come which claims chat history for famous people like Shushant Singh Rajput, Arnab Goswami, etc.  So one question is always comes to our mind that Is our WhatsApp chat really secured? Is our privacy is in danger? Is WhatsApp read our messages? and many more.
In this article, we cover all these questions in detail.

What is End to End Encryption & How it Works in WhatsApp?

Encryption is a way to hide actual information. Suppose you type a sentence “I LOVE INDIA” nowhere for encryption purpose you increase an alphabet letter in your syntax.  means A converts into B, D converts into E. So now our actual sentence convert into this
I LOVE INDIA –> J MPWF JOEJB
Here you can see our encrypted sentence is  “J MPWF JOEJB“.
Are you able to understand this encrypted sentence? No
Here this is basic encryption which a person can decrypt if he works on this a few times. In computer science, Many encryption algorithms are developed. An algorithm is a setup of rules which executed one by one.  In the above example, we only set a single rule (increase one letter in the alphabet). But Algorithms are too powerful which creates a large unreadable format. For Example md5 encryption algorithm
I LOVE INDIA in md5 is 5a060cff328160014ca78cee07c8c3a1
Here you can the result string is not a human readable format.

Here many algorithms provide encryption as well as decryption, for security reasons they also offer a SALT facility. SALT is a custom user string that impacts the working of encryption and also affects encryption results. For example, user1 salt is 512 & user2 salt is 421. Now both encrypt the same message but the encryption result is different due to their SALT.

Whatsapp End to End Encryption Working:

In the above example, you learn how encryption works. WhatsApp follows the same encryption and decryption method (Algorithm) to process chat messages but SALT is different for every user. You may notice if you complete uninstall WhatsApp OR Install WhatsApp on another device then your security token will change. and your contacts also see that your security token changed. Every message which you send is encrypted with the help of your security token and decrypted on the recipient’s device with the help of his token and the WhatsApp encryption algorithm is very good and very hard to decrypt without a user token and WhatsApp also deletes the message once delivered to the recipient.
Here If a WhatsApp employee wants to see your message in the database then this is in an encrypted format so he cannot understand the actual message. So here we can say WhatsApp provide the best end to end encription chat service.

Why WhatsApp chat leaks Even after strong Encryptions:

In the above para, we explain how the end to end encryption works in WhatsApp. As we all know WhatsApp provides strong encryption on chats but still news of chat leaks comes on the internet.

For example, iOS provide a service to the developer which not available on Android. Then what?
So WhatsApp needs to take care of all of these things.

WhatsApp’s major drawback is, they don’t offer a cloud chat backup service. They are dependent on the third-party cloud provider.
