CyanogenMod has announced that it is shutting down its WhisperPush secure message functionality. The secure messaging service automatically encrypted text messages sent between two CyanogenMod users.
CyanogenMod said that as this is a server side implementation, all branches of CM from CM10.2 and forward will be affected. The company said that it was facing problems like longstanding registration issues & issues with various countries, which has made it shut down the support for WhisperPush secure message functionality. CyanogenMod is asking users to download a newly released Signal app that combines TextSecure (encrypted text) and RedPhone (encrypted voice) capabilities. The Signal open source application has been created by Open Whisper Systems which had also played an important role in implementation of WhisperPush. It is available in the Play Store.
CyanogenMod said if your current device & number is registered with WhisperPush, you can unregister via the Settings > Privacy > WhisperPush directly via the device (CM10.2 – CM12.1). After February 1st 2016, messages will no longer go through itsservice, and will be sent as regular SMS messages instead.
