Hello users, I hope you are well. Today we talk about WhatsApp encryption from start to finish, how it works and how it can be leaked, as well as the secure chat options available. As we all know, WhatsApp offers end-to-end encryption on its chat platform. As users, we always think that our chats are encrypted, but recently many messages have surfaced claiming the chat history of famous people like Shushant Singh Rajput, Arnab Goswami, etc.  So the question always comes to us: Is our WhatsApp cat really safe? Is our privacy under threat? Is WhatsApp reading our messages? And much more.
In this article we will discuss all these points in detail.

WhatsApp end-to-end encryption in chat – works

What is encryption and how does it work on WhatsApp?

Encryption is a way to hide real information. Suppose you enter the phrase I LOVE INDIA and, for encryption reasons, do not increase the letter of the alphabet in the syntax. This means that A is converted to B, D is converted to E. So our current sentence becomes this
I LOVE INDIA -> J MPWF JOEJB
Here you see our encoded sentence – J MPWF JOEJB.
Can you understand this code phrase? No.
It’s a simple code that someone can decipher if they work on it repeatedly. Many encryption algorithms have been developed in computer science. An algorithm is a set of rules that are executed in sequence.  In the above example, we have set only one rule (increment a letter in the alphabet). But the algorithms are too powerful, resulting in a large unreadable format. For example, the md5 encryption algorithm is
I LOVE INDIA in md5 5a060cff328160014ca78cee07c8c3a1
Here you get the result string in a non-human readable format.

Here, many algorithms provide both encryption and decryption, including SALT for security reasons. SALT is a user string that affects both encryption performance and encryption results. Example: Salt user1 is 512 and salt user2 is 421. Now both encrypt the same message, but the result of the encryption is different because of their SALT.

How End-to-End Encryption Works :

In the example above, you will learn how encryption works. WhatsApp uses the same encryption and decryption method (algorithm) to process instant messages, but the SALT is different for each user. You may notice that after deleting WhatsApp or installing WhatsApp on another device, your security token changes and your contacts also see that the security token has changed. Every message you send is encrypted with a security token and decrypted on the recipient’s device with the token. WhatsApp’s encryption algorithm is very good and very difficult to decode without the user’s token, and WhatsApp deletes the message after it is delivered to the recipient.
Here When a WhatsApp employee wants to see your message in the database, it is in an encrypted format so they cannot understand the message itself. It can be said here that WhatsApp offers the best investment in end-to-end chat services.

All possible ways to prevent cat leaks in WhatsApp

Why the WhatsApp cat leaks, even after strong encryption:

In the section above, we explained how end-to-end encryption works in WhatsApp. As we all know, WhatsApp offers strong encryption in chats, but messages from chat leaks still arrive on the Internet. Here we try to understand why this happens. As we all know, WhatsApp offers its services for different devices that can run Android, iOS, Windows, Blackberry, KaiOS, etc. This is where WhatsApp relies on operating system services. For example, iOS offers the developer a service that is not available on Android. What’s next?
So WhatsApp has to take care of all these things.

The biggest drawback of WhatsApp is that it does not offer a backup service for cats in the cloud. You are dependent on an external online service provider.
1. For Android – depends on Google Drive
2. For iOS – Depends on iCloud.

• The chat secured by the WhatsApp application is not end-to-end encrypted. This way, someone who has access to your Google account can download a backup of your chat and view your discussions.
• If someone has access to your phone, they can also access your chat backup through the file manager and can easily move/copy the entire backup from your device to theirs using any file transfer application like Xender, SHAREit, etc.
• If someone has your phone, they can take screenshots and transfer them to their phone using file transfer applications such as Xender, SHAREit, etc.
• If someone installed a spy app on your phone. With the spy app, it can see all your messages and other activities like Instagram chat, head messages, messenger chats, street chats and much more. To learn more about spyware applications, click here.

Here we show you possible ways to control your WhatsApp messages without your permission.

Is switching to another application like Signal to protect our privacy the right decision?

Currently, WhatsApp offers encryption in private and group conversations. So there is no reason to modify your application. Assuming you decide to use Signal App, what happens if the owner of Signal App turns your product into a non-profit and sells the entire company to Google or Microsoft. and the next owner changes the privacy policy again. So what do you do?
You know that WhatsApp and the Signal application were founded by the same person.
For now, WhatsApp is a good option because they still offer end-to-end encryption. For example, to protect your Google account. B. With 2 factor authentication and activation of Google Play security service on your Android mobile device, you just need to know a few basic technical tips.
