Signal Private Messenger

Signal Private Messenger is a free encrypted messaging application for smartphones. It was originally called TextSecure and developed by Signal Foundation. This app uses the ZRTP protocol to provide end-to-end encryption. This means that the content of the message is encrypted on the sender's device and decrypted on the receiver's device. No one can intercept the message in between. The encryption key is ephemeral and is discarded after the message is read.

Signal Private Messenger has a simple and clean user interface. It is available for Android and iOS. It supports text messages, photos, videos, and voice messages. It can also send location and contact information and supports group messaging.

Functionality

You can send messages to anyone, even if they're not using Signal. Signal uses your existing phone number and address book. There are no separate logins, usernames, passwords, or PINs to manage or lose.
