WhatsApp will start rolling out the end-to-end encryption for chat backups it introduced in September for its customers globally on Android and iOS gadgets.
The Fb-owned messaging service has greater than 2 billion customers globally and over 400 million in India. These customers ship greater than 100 billion messages a day.
With this replace, if somebody chooses to again up his chat historical past with end-to-end encryption, will probably be accessible solely to him, and nobody will have the ability to unlock the backup, not even WhatsApp. Neither WhatsApp nor the backup service supplier (like Apple) will have the ability to entry their end-to-end encryption key or their end-to-end encrypted backup.
“Beginning in the present day, we’re making accessible an additional, non-compulsory layer of safety to guard backups saved on Google Drive or iCloud with end-to-end encryption. No different international messaging service at this scale gives this stage of safety for his or her customers’ messages, media, voice messages, video calls, and chat backups,” WhatsApp stated in a weblog submit explaining how this further layer of safety will work.
Customers can now safe their end-to-end encrypted backup with both a password of their selection or a 64-digit encryption key that solely they might know. Neither WhatsApp nor its backup service supplier will have the ability to learn their backups or entry the important thing required to unlock it.
Encryption is the observe of scrambling information to make it unintelligible for even the service suppliers. It retains conversations personal, and end-to-end encryption means solely the meant sender and receiver can see the messages being despatched.
A significant problem and query with WhatsApp’s chat backups was that these are saved with third occasion cloud suppliers like Google (Drive) or iCloud.
“Previous to the introduction of end-to-end encrypted backups, backups saved on Apple iCloud and Google Drive weren’t protected by WhatsApp’s end-to-end encryption. Now we’re providing the flexibility to safe your backups with end-to-end encryption earlier than they’re uploaded to those cloud providers,” WhatsApp stated earlier in a whitepaper explaining the know-how behind this new replace.
