Threema Android is a secure messaging application with end-to-end encryption using NaCl/libsodium. It features a modular architecture following clean architecture principles with separation into app, domain, data, and common layers. The app uses MVVM with ViewModels and StateFlow/LiveData, dependency injection via Koin, and Kotlin coroutines for asynchronous operations. Key functionality includes text/media messaging, voice/video calls, group chats, polls, contact management, backup/restore, multi-device synchronization, and availability status indicators. The application supports multiple build variants for different distribution channels (Google Play, Huawei AppGallery, F-Droid, Threema Shop) and includes enterprise features for business users. It relies on SQLCipher for encrypted local storage, implements custom CSP/D2M protocols for server communication, and provides web client functionality for desktop access.
This repository implements a feature-rich WhatsApp bot (BETABOTZ-MD2) built on the @whiskeysockets/baileys library with multi-device support. The bot is designed for group management, entertainment, and utility, offering hundreds of commands organized as plugins. Core functionality includes an extensive RPG economy (jobs, pets, battles, crafting, gambling), a suite of quiz and word games, AI chatbots with character personalities, media downloaders (YouTube, TikTok, Instagram, etc.), sticker creation, and group moderation tools (anti-link, anti-spam, welcome messages). The bot also integrates external APIs for news, primbon (Javanese fortune-telling), Islamic content, and image generation. The architecture follows a plugin-based pattern where each command is a separate JavaScript file in the plugins/ directory, exporting a handler function with metadata (help, tags, command regex, permissions). The core bot logic resides in an obfuscated main.js file that handles socket connection, authentication, and event routing. Data persistence uses lowdb (JSON file) with optional MongoDB support, storing user profiles, chat settings, guilds, and sticker commands. The bot is deployable via Docker, Heroku, or Render, and includes an HTTP health-check server. A critical dependency is the external API at api.betabotz.eu.org, which powers most downloaders, AI, and content features. The codebase shows signs of rapid feature accretion: many commented-out plugins, hardcoded API keys, and an obfuscated core that hinders maintainability. Despite these issues, the plugin system and game logic modules (e.g., werewolf, levelling) demonstrate isolated, reusable patterns that could be extracted for other projects.
