Swoosh Messenger

ont besoin d'intimité, Swoosh Permet

Swoosh Messaging app provides a secure means of comunicating with your peers.

Built using open whispers signal framework, Swoosh uses your standard cellular mobile numbers as identifiers, and uses end-to-end encryption to secure all communications to other users. The applications include mechanisms by which users can independently verify the identity of their messaging correspondents and the integrity of the data channel.

Swoosh allows users to make voice and video calls to other users. All calls are made over a Wi-Fi or data connection and (with the exception of data fees) are free of charge, including long distance and international.

It also allows users to send text messages, files,voice notes, pictures, GIFs and video messages over a Wi-Fi or data connection to others. The apps also support group messaging.

All communications to other users are automatically end-to-end encrypted. The keys that are used to encrypt the user's communications are generated and stored at the endpoints (i.e. by users, not by servers).

Swoosh also has a built-in mechanism for verifying that no man-in-the-middle attack has occurred. For authentication, users can compare key fingerprints (or scan QR codes) out-of-band The app employs a trust on first use mechanism in order to notify the user if a correspondent's key changes.

Users can opt into making Swoosh the default SMS/MMS application, allowing them to send and receive unencrypted SMS messages in addition to the standard end-to-end encrypted messages. Users can also opt into allowing Signal to fall back to unencrypted SMS/MMS when communicating with contacts who do not have Swoosh or Signal Installed

Swoosh also allows users to set timers to messages.After a specified time interval, the messages will be deleted from both the sender's and the receivers' devices. The time interval can be between five seconds and one week long, and the timer begins for each recipient once they have read their copy of the message. T
