End to End Encryption (E2EE) 
End to End Encryption

The end to end encryption system, which means absolute end-to-end encryption of the conversations that take place through the WhatsApp application from the moment you press the word send until your message appears on the screen of the receiving person. 

This system prevents any third party from accessing users’ messages, even the company itself, where this is distinguished The system generates the encryption key for messages automatically without interference from the application, and then stores this key in the phone’s memory itself, not on WhatsApp servers, and without even going through it. 

It is the complete encryption between the two parties used by many companies that provide instant messaging services such as WhatsApp, signal, imessage and others. This encryption is of the type asymmetric or asymmetric encryption and the idea of ​​encryption is based on the public key and the private key (public & private keys).

When you register in a chat service, you are given public and private keys. The private key always stays with you, and the public key is your address, so when you send a message or receive a message, it will be your interface.

When you send a message to someone, it is encrypted with that person’s private key.

Upon receiving it, that person can read it normally because the private key is with him.

But if a message is sent to the wrong person, the message will appear in the form of symbols, as the wrong person does not have the private key to open the message.

As we note in this type of encryption, the service servers are not mentioned, because they are actually a medium for passing encrypted messages and keeping them encrypted.

That is why this method of encryption was called End-to-end Encryption or end-to-end encryption, because the service servers are never able to open messages.
