After being part of CyanogenMod for two years, the end of the road has come for WhisperPush. The project announced today that it would end support for its own implementation of the secure messaging protocol developed by Open Whisper Systems.
WhisperPush automatically encrypted text messages sent between two CyanogenMod users or someone running TextSecure. The functionality first appeared in CyanogenMod 10.2 thanks to work by Open Whisper Systems' lead engineer Moxie Marlinspike. In the time since, CyanogenMod encountered a few issues, particularly related to registering users. Then once Open Whisper System made significant upstream changes, the project decided that further work would result in an unnecessary fork.
Signal, the combination of TextSecure and RedPhone, offers a cross-platform solution that CyanogenMod users can install without any additional effort from developers.
WhisperPush is not available in CyanogenMod 13.0, which brings Android 6.0 to devices running the custom ROM. Folks running 12.1 or prior will see the service stop running starting February 1st. Anyone looking to migrate to Signal can do so at the link below.
