Whatsapp End-to-End Encryption Supports For All Messages,photos, phone calls and videos sent over its messaging app this means that no one can access any communications apart from the people in the conversation.
Update: WhatsApp has now published a blog post on the move, saying:
“Encryption is one of the most important tools governments, companies, and individuals have to promote safety and security in the new digital age. Recently there has been a lot of discussion about encrypted services and the work of law enforcement. While we recognize the important work of law enforcement in keeping people safe, efforts to weaken encryption risk exposing people’s information to abuse from cybercriminals, hackers, and rogue states.”
End-to-end encryption means the content of communications are not stored in plaintext on WhatsApp’s servers. Nor is the company able to decrypt users’ messages to access them since it does not hold the encryption keys. So WhatsApp will be unable to be compelled to hand over messaging data — even if served with a warrant by authorities demanding access.
By most reports, WhatsApp is the largest messaging service in the world with over a billion users. Going forward, all of the private communications taking place on the service will be truly private.
