WhatsApp's latest update for Android users offers more privacy

WhatsApp has started rolling out another update for its Android users that includes an end-to-end encryption of chats enabled by default.

This is the strongest security offered by a texting app even when compared to similar tools offered by giants like Google, Apple and Microsoft.

Other apps like Cryptocat, Silent Text and Telegram do provide end-to-end encryption but with over 600 million users across the world, WhatsApp is the largest texting platform to adopt the system.

The Facebook-owned messaging app has teamed up with Open Whisper Systems for the launch and used open source code to build-in the new features. However, it's unclear when the company will introduce the features for its iOS users.

Unlike messages encrypted by Gmail or Facebook chat, an "end-to-end" encryption would mean that even WhatsApp will not be able to decrypt the messages even when compelled by law enforcement.

The company will set up the key exchange between users but only the two users will be have access to the conversation itself.
