What is End-To-End Encryption in WhatsApp?

Normally, when we send any message to others through WhatsApp, that message would reach WhatsApp servers first, then that would be sent to the recipient. So, WhatsApp servers have our messages. This would be dangerous as when someone hacks WhatsApp servers, then our data is stolen and it will become public.

To arrest these things before happening, WhatsApp has introduced end-to-end encryption. With this when a message has been sent through WhatsApp, then that would get encrypted (not readable by human and hard to decode) in the sender’s device and it would directly get decrypted (decoded) in the receivers device. No one could know what the message is sent from sender to receiver including WhatsApp.

Yes. With this end-to-end encryption your data or message would be safe from intruders, hackers, government agencies, cyber criminals, oppressive regimes and from other dangerous mechanisms. Now, the message, images, videos, calls and everything will be shared only between you and your recipient.

What is End-To-End Encryption?

End-To-End Encryption used by WhatsApp is Public Key Encryption. To explain in short, when user sends a message through WhatsApp, then that would be sent with a key. This message would only be decrypted at the receiver’s side with the same key. So, these keys will be available only with the sender and receiver and not with anyone else.

WhatsApp has made this end-to-end encryption as a default settings and this cannot be disabled. Users need to update the WhatsApp with the latest version.
