ChatSecure

Build Status

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

You'll need Cocoapods for most of our dependencies.

$ 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/ChatSecure/ChatSecure-iOS.git
$ cd ChatSecure-iOS/
$ git submodule update --init --recursive

Now you'll need to build the dependencies. During this process we will automatically verify the integity of each package by checking its GPG signature. Install GPGTools and add the public signing keys for OpenSSL, GnuPG, libevent, and libotr. (TODO make these links to the keys)

$ bash ./Submodules/CPAProxy/scripts/build-all.sh
$ bash ./Submodules/OTRKit/scripts/build-all.sh
$ pod install

Next you'll need to create your own version of environment-specific data. Make a copy of OTRSecrets-Template.m as OTRSecrets.m:

$ cp ChatSecure/Classes/Utilities/OTRSecrets-Template.m ChatSecure/Classes/Utilities/OTRSecrets.m
$ cp ./configurations/OTR_Codesigning.xcconfig.sample ./configurations/OTR_Codesigning.xcconfig

Then set your own value for PROVISIONING_PROFILE_Debug in OTR_Codesigning.xcconfig to your iOS team provisioning profile identifier to run it on your device. You can get this identifier by temporarily selecting the desired profile in Xcode (Build Settings -> Provisiong Profile), then selecting "Other...".

Open ChatSecure.xcworkspace in Xcode and build.

Note: Don't open the .xcodeproj because we use Cocoapods now!

If you're still having trouble compiling check out the Travis-CI build status and .travis.yml file.
