End-to-end encryption is a system that protects the data/message and all your files in the form of videos, photos, online conversations, etc. by making them unreadable by the unauthorized person who is not the recipient. The message travels in an encrypted form from sender to receiver. Both the service provider and the person with access are not able to decode the conversation or the documents that are exchanged. In this manner, end-to-end encryption guarantees you maximum security.
All communication systems cannot guarantee communication protection between the sender and receiver as they do not use end-to-end encryption. End-to-end encryption is considered the safest as it reduces the number of participants in the process of encryption who can decode or change communication.
End-to-end encryption facilitates communication that is totally in encrypted form and only the sender & receiver can see or read the message. No one in the middle can see or encrypt the message being sent from one device to another device.
The messages you send or the communication that happens are decrypted at the endpoint – the device you are sending messages to. The server you are sending the data through will not be able to decrypt or view the message. In other words, end-to-end encryption uses the server only for transmitting the data through the two devices, it does not allow the server to decrypt the data. Therefore, the server is just a medium to transfer the data of encrypted information.
End-to-end encryption, nowadays, is a very important and most effective solution to protect the data.
Security professionals and privacy experts highly support the idea of end-to-end encryption as it better protects your data from unauthorized access or hackers and other parties who may want to steal your information. It protects the data and information of millions of people and assures the privacy of their information. For this reason, experts are advocating the use of end-to-end encryption in messaging apps.
