WhatsApp now provides end-to-end encryption via TextSecure on Android



WhatsApp has finally deployed end-to-end chat encryption for all Android users, making it the first popular messaging service to fully adopt the TextSecure encryption protocol originally developed by Open WhisperSystems.

The new encryption is a huge upgrade from WhatsApp previous encryption system, end-to-end encryption implemented in TextSecure ensures that any data transmitted between your phone (client) and WhatsApp servers is fully encrypted, making it impossible for prying eyes to eavesdrop on your messages. This means that even WhatsApp won’t be able to decrypt the messages itself, even if compelled by governmental agencies or law enforcement requests.

The most recent WhatsApp Android client release includes support for the TextSecure encryption protocol, and billions of encrypted messages are being exchanged daily. The WhatsApp Android client does not yet support encrypted messaging for group chat or media messages, but we’ll be rolling out support for those next, in addition to support for more client platforms. We’ll also be surfacing options for key verification in clients as the protocol integrations are completed.

The update is also set to land on iOS on on other platforms at some point in the future, this shouldn’t really come to a surprise considering that it took WhatsApp a whopping 6 months to get their code ready for this upgrade.
