Silence (formerly SMSSecure) is an SMS/MMS application that allows you to protect your privacy while communicating with friends.
Using Silence, you can send SMS messages and share media or attachments with complete privacy.
- Easy. Silence works like any other SMS application. There's nothing to sign up for and no new service your friends need to join.
- Reliable. Silence communicates using encrypted SMS messages. No servers or internet connection required.
- Private. Silence uses the Axolotl encryption protocol to provide privacy for every message, every time.
- Safe. All messages are encrypted locally, so if your phone is lost or stolen, your messages are protected.
- Open Source. Silence is Free and Open Source, enabling anyone to verify its security by auditing the code.
Silence focuses on SMS and MMS. This fork aims to:
- Keep SMS/MMS encryption
- Drop Google services dependencies (push messages are not available in Silence)
- Integrate upstream bugfixes and patches from TextSecure
Migrating from TextSecure to Silence
- In TextSecure, export a plaintext backup. Warning: the backup will not be encrypted.
- Install Silence.
- In Silence, import the plaintext backup (this will import the TextSecure backup if no Silence backup is found).
- If TextSecure v2.6.4 or earlier is installed, update or uninstall it so it doesn't conflict (can cause errors with key exchanges).
- Enjoy Silence!
Note: You will have to start new secured sessions with your contacts.
See CONTRIBUTING.md for how to contribute code, translations, or bug reports.
Instructions on how to setup a development environment and build Silence can be found in BUILDING.md.
