Whatsapp has enabled end-to-end encryption on its messaging app. The Facebook owned instant messaging app has taken its encryption a step further by implementing procedures that makes it harder for law enforcement agents to access communications.
WhatsApp’s founders said Tuesday that the application now implements end-to-end encryption, which means only authorized users can decrypt messages.

“The idea is simple: when you send a message, the only person who can read it is the person or group chat that you send that message to,” Jan Koum and Brian Acton wrote in a blog post. “No one can see inside that message. Not cybercriminals. Not hackers. Not oppressive regimes. Not even us.”
The move by WhatsApp comes after fierce debate over the increasing use of encryption and how it affects law enforcement investigations. WhatsApp said in February it had 1 billion users.
