Web and Mobile Chat Application using SignalR and ASP .NET Core 8.0

This project is a cross-platform chat application for both web and mobile, developed using SignalR and ASP.NET Core 8.0. The application supports real-time messaging with advanced features like public and private chat modes. Additionally, it includes End-to-End Encryption (E2EE) to ensure secure communication by encrypting messages on the client side, making them accessible only to the intended recipients.

• Text and Image Messaging: Supports sending both text messages and images across web and mobile platforms.

• Public and Private Chats: Users can switch between public rooms or private, encrypted conversations.

• Cross-platform Compatibility: Accessible on both web and mobile platforms.

Technologies Used:

• Web: React

• Mobile: Fluter

• Backend: ASP.Net Core 8.0

• Real time : SignalR

• Database: MongoDB

• Encryption: E2EE, AES, RSA

Note: the E2EE feature is in the Crypto branch
