SMSSecure is an SMS/MMS application that allows you to protect your privacy while communicating with friends.

Using SMSSecure, you can send SMS messages and share media or attachments with complete privacy.

Features:

• Easy. SMSSecure works like any other SMS application. There's nothing to sign up for and no new service your friends need to join.
• Reliable. SMSSecure communicates using encrypted SMS messages. No servers or internet connection required.
• Private. SMSSecure uses the TextSecure 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. SMSSecure is Free and Open Source, enabling anyone to verify its security by auditing the code.

This is a fork of TextSecure that aims to keep the SMS encryption that TextSecure removed for a variety of reasons.

SMSSecure focuses on SMS and MMS. This fork aims to:

• Keep SMS/MMS encryption
• Drop Google services dependencies (push messages are not available in SMSSecure)
• Integrate upstream bugfixes and patches from TextSecure

• In TextSecure, export a plaintext backup. Warning: the backup will not be encrypted.
• Install SMSSecure.
• In SMSSecure, import the plaintext backup (this will import the TextSecure backup if no SMSSecure 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 SMSSecure!

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 SMSSecure can be found in BUILDING.md.
