Glacier Chat
Glacier Chat is a free and open source XMPP messaging client for iOS that is based on ChatSecure and that integrates OMEMO encrypted messaging support.
Glacier Messenger is free to download and use (thanks to ChatSecure and the GPLv3 license). However, the changes made to the ChatSecure base product were intended to optimize Glacier Messenger for use with the full set of Glacier Security services, so Glacier Messenger may not be the best choice for those looking for a one size fits all solution. For an iOS messaging client that works with most modern XMPP servers, see ChatSecure.
Glacier Security is a full-service provider of secure, end-to-end encrypted, and anonymous communication solutions for enterprise and government. Our cloud based immutable infrastructure is launched automatically for each customer leveraging concepts of Department of Homeland Security’s Moving Target Defense project. Glacier controls change across multiple system dimensions in order to increase uncertainty for attackers, reduce their window of opportunity, increase the costs of their attack efforts, and keep end user devices anonymous.
Because Glacier services typically run within a private network, numerous assumptions were purposefully made to optimize and simplify usage for this specific scenario. Some of these design choices are not recommended for use outside of a Glacier network.
Note: Some of the instructions, directories, and files reference ChatSecure because Glacier Chat is based on ChatSecure-iOS.
You'll need CocoaPods installed for 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://[email protected]/glaciersec/ios-messenger.git
$ cd ios-messenger/
$ git submodule update --init --recursive
Now you'll need to build the dependencies.
$ bash ./Submodules/OTRKit/scripts/build-all.sh
$ pod repo update
$ pod install
Next you'll need to create your own version of environment-specific data. Make a copy of Secrets-template.plist as Secrets.plist:
$ cp OTRResources/Secrets-template.plist OTRResources/Secrets.plist
Glacier Chat currently uses AWS Amplify to facilitate single signon model across the platform of Glacier applications. As part of this, the AWS Cognito and S3 IDs need to be added to the Secrets.plist file. Single signon also makes use of AWS Amplify, and thus to be used in this way would need to setup Amplify and a related backend environment. See AWS Amplify documentation.
You'll need to manually change the Team ID under Project -> Targets -> ChatSecure -> Signing. The old .xcconfig method doesn't seem to work well anymore.
Open Glacier.xcworkspace in Xcode. Before building, there is an error in the SQLite.swift pod that needs to be fixed. Unfortunately the fix requires making a change to the pod which requires unlocking the file. The change is to SQLite.swift/standard/fts3_tokenizer.h.
$ On line 27, change #import "sqlite3.h" to #import <sqlite3.h>.
In SQLCipher/sqlite3.h and sqlite3.c, change #ifndef SQLITE3_H to #ifndef SQLITE3_H (underscore before and after, not sure why its not showing up correctly) due to a conflict that SQLite.swift creates. This matches the definition of the sqlite3 that comes with iOS.
Also added the following in MMEEventsManager (used by MapBox) to avoid an issue with background thread
$ else if (!appIsInBackground && _backgroundTaskIdentifier != UIBackgroundTaskInvalid) { //line 190
UIBackgroundTaskIdentifier taskId = self.backgroundTaskIdentifier;
self.backgroundTaskIdentifier = UIBackgroundTaskInvalid;
[self.application endBackgroundTask:taskId];
}
$ pauseOrResumeMetricsCollectionIfRequired NS_EXTENSION_UNAVAILABLE("not available in extensions")
Then, build in XCode.
Note: Don't open the .xcodeproj because we use Cocoapods!
