With end-to-end encryption your messages, photos, videos, voice messages, documents, status updates and calls are safe. It is available when you and the clients to whom you are sending messages are using a recent version of WhatsApp.
The security and privacy of our customers are part of our DNA, hence we provide end-to-end encryption in the most recent versions of our app.
The end-to-end encryption in WhatsApp ensures that only you and the receiver can read what is sent, and that no one else, not even WhatsApp, can do it.
Your messages are secured with a lock and only you and the receiver have the special code / key to open it and read the messages. For greater protection, each message you send has its own padlock and unique code. All this happens automatically without you having to make adjustments or create secret chats to secure your messages.
It is very important that you know that there is no way to disable or turn off encryption from end to end.
Each of your chats has a unique security code that is used to confirm that the calls and messages you send to that chat are encrypted end-to-end.
The verification process is optional and is used only to confirm that the messages you send are encrypted end-to-end. This code is on the contact’s information screen as a QR code and as a 60-digit code. These codes are unique for each chat and can be compared with the contacts of each chat to confirm that the messages you send to that chat are encrypted from end to end.
If you are physically with your contact one of the two can scan the QR code of the other or compare the 60-digit security code visually. If you scan the QR code and the code matches, a green tick will appear. By matching the codes, you can be sure that nobody is intercepting your messages or calls.
If the codes do not match, you may be scanning the code of a different contact or terminal number
If you are not physically with your contact, you can send them the 60-digit code.
Security is very important for the service that WhatsApp provides. In 2016, end-to-end encryption was implemented for all WhatsAp messages and calls in such a way that we do not have access to the content of your conversations.
WhatsApp has no way to see the content of your messages or listen to your calls on WhatsApp because the encryption and decryption of messages sent through WhatsApp occurs completely on your terminal.
The keys change with each message sent and before the message leaves your terminal it is secured with a cryptographic padlock and only the recipient has the password.
