WhatsApp safeguards the conversations that take place on its platform using end-to-end encryption. This ensures that no one, not even WhatsApp, is able to check the contents of a chat. However, this safety measure is not extended to chat backups on Google Drive. To protect users’ conversations, WhatsApp is working on a new feature that will protect chat backups using the same technique that it uses to safeguard messages being exchanged on its platform.
The blog site says that WhatsApp is clarifying that the 64-digit encryption key can only contain numeric digits and lowercase letters between letters ‘a’ and ‘f’. WhatsApp wants to use hexadecimal for encrypting chat backups. The blog site says that this feature will protect users’ chat backups from unauthorised access on Google Drive with a password that won’t be shared on Facebook, WhatsApp, Google or Apple.
As far as availability is concerned, the encrypted chat backups feature is still in the developmental phase. It will be available on WhatsApp for Android beta with future updates.

Separately, WhatsApp is also working on changing the colour of UI elements in chat notifications on Android. In a separate report, the blog site says that WhatsApp is planning to change the colour of Reply and Mark as Read buttons from dark Green to dark Blue when Dark Mode has been enabled. This feature is available in version 18.104.22.168 of WhatsApp’s Android beta app. The company is also planning to change the colour of these elements in light mode. But that change isn’t visible to all beta testers yet. This development follows another move by WhatsApp wherein the company changed the colour of the profile icon of individual and group, where no image had been set, from a Grey to Blue.
