End-to-end encryption for all Whatsapp messages …but not for spreadsheets!

By Matthew Cheung

Hot on the heels from the security fob off from Apple to the US government, WhatsApp is updating its messenger app with strong encryption so that every text and voice call will be highly protected for their 1 billion+ users.

After starting the process in 2014, Facebook owned Whatsapp have fully completed their roll out of Signal Protocol to all of their app users. Developed by Open Whisper Systems, the open source code was made famous by US whistleblower and privacy advocate Edward Snowden.


What does end-to-end encryption mean?

In a nutshell, end-to-end encryption means only the sender and receiver can view a message and no content or information is visible on Whatsapp’s servers without encryption keys, something which Whatsapp does not store, also commonly known as zero-knowledge. Messages are encrypted before they leave a users device which means that if the US government demanded to see users communications, Whatsapp would be unable to provide it due to the encryption and Whatsapp does not store the key to decrypt it.
