ChatSecure is a free and open source encrypted chat client for iPhone and Android that supports OTR encryption over XMPP.

ChatSecure

ChatSecure is a free and open source instant messaging client for iOS and Android that integrates encrypted OTR ("Off the Record") messaging support from the libotr library and the XMPPFramework to handle Jabber/GTalk (XMPP).

Cost

This project is 100% free because it is important that all people around the world have unrestricted access to privacy tools. However, developing and supporting this project is hard work and costs real money. Please help support the development of this project! We now also accept Bitcoin via Coinbase! :)

Build Instructions

Install mogenerator in order to regenerate the Core Data model files. You'll also need Cocoapods for some of our dependencies.

$ brew install mogenerator
$ gem install cocoapods

Download the source code and don't forget to pull down all of the submodules as well.

$ git clone https://github.com/chrisballinger/ChatSecure-iOS.git
$ cd ChatSecure-iOS/
$ git submodule update --init --recursive
$ pod install

Make your own version of environment-specific data. Make OTRSecrets.m file with blank API keys.

Open ChatSecure.xcworkspace in Xcode and build. Note that you don't open the .xcodeproj anymore because we use Cocoapods now.
