[FREE] Kodular Community Chat Client and Server

Kodular Community Chat Client and Server

Welcome to our Kodular Community project, where we are thrilled to offer a comprehensive client and server setup for chat applications. This project provides a Kodular-built chat client and a Java-based chat server that orchestrates encrypted communications.

Chat Server in Java

The heart of our communication platform is a Java chat server, crafted to enable secure message exchanges. It’s designed to handle multiple connections, ensuring each message is encrypted and broadcast securely to connected clients.

Key Features:

  • Concurrent client management with multithreading
  • Robust AES encryption for message security
  • Server activity monitoring through console-based logging

How to Run:

  1. Clone or download the server Java files from the repository.
  2. Compile the server with javac ChatServer.java.
  3. Start the server using java ChatServer.

Make sure Java is installed on your system to compile and run the server.

Kodular Chat Client

Complementing our server is the Kodular chat client, which offers users a seamless and secure platform to send and receive messages right from their Android devices.


  • User-friendly interface for message exchange
  • End-to-end encryption for privacy and security
  • Seamless integration with the Java chat server

How to Use:

  1. Access the Kodular project and tailor it to your needs.
  2. Build the project within Kodular to generate an Android-compatible APK.
  3. Deploy the APK on your Android device and engage in secure conversations.

Enhancing Security

To further solidify the application’s security posture, we’re looking into adding SSL/TLS encryption for communication and incorporating a secure protocol for the exchange of AES keys.

Next Steps:

  • Implementation of SSL/TLS within the Java server for enhanced encryption.
  • Integration of a secure key exchange mechanism.
  • Development of user authentication for controlled server access.
  • Expansion of client functionalities, including group chat and file sharing capabilities.

Community Collaboration
