    Novel Insight Inner Circle

    Novel Insight Inner Circle

    Graphical message and file encryption tool

    Novel Insight Inner Circle is a message and file encryption tool for Windows. The software is developed in Java and requires 64bit Java JRE. The encryption uses AES-256 twice so it is harder to crack than the industry standard pure AES 256bit implementation (theoretical key size is 512 bit). The software writes encrypted data in ASCII text format which can be cut'n'pasted to messaging apps or to emails and back to Inner Circle when decrypting data. IMPORTANT: The software requires new OpenJDK 16 (Not Oracle's J2RE 1.8) to run. Install, for example, AdoptOpenJDK for Windows. NOTE: By using encryption twice the implementation is (in theory) vulnerable to Meet-In-The-Middle attack reducing key size to 256bit but the attack still requires 2^256 bytes of memory making it impossible in practice.

    Official Android SDK for Stream Chat

    Official Android SDK for Stream Chat

    Android Chat SDK ➜ Stream Chat API. UI component libraries for chat

    This is the official Android SDK for Stream Chat, a service for building chat and messaging applications. This library includes both a low-level chat SDK and a set of reusable UI components. Most users start with the UI components and fall back to the lower-level API when they want to customize things. We're proud to say that we're the first Android Chat SDK that supports Jetpack Compose! We released our Compose UI Components one day after the official Jetpack Compose 1.0 release and our team members have been working hard on it since then. Now it's mature and stable enough for us to officially recommend it for all new applications and all modern chat implementations. If you're looking for something highly customizable and extremely performant, check out our Compose SDK.
