Build an Encrypted Messaging App for Android
In this tutorial, we’ll build an encrypted chat/messaging example app for Android. To do this, we will combine both Stream Chat and Virgil Security platforms.

These two services allow developers to integrate chat that is zero knowledge to your backend or Stream. The example app embeds Virgil Security’s eThree Kit — a secure encrypted messaging platform — with Stream Chat’s Android components.
Note that all source code for this example, Android app is available on GitHub. Additionally, before jumping into this tutorial, I recommend checking out the Stream Chat Android tutorial, which will walk you through how to implement Stream Chat from a high-level overview.
