Secure DTLS Server

This project implements a DTLS (Datagram Transport Layer Security) server for secure communication over UDP using OpenSSL. It connects to a DTLS server and performs authentication using X.509 certificates.

📌 Requirements

• Operating System: Linux or macOS (Windows may require modifications)
• Compiler: GCC (minimum gcc 7.5.0) or Clang

Install Dependencies

For Debian/Ubuntu:

$ sudo apt update
$ sudo apt install -y libssl-dev build-essential

For macOS (with Homebrew):

brew install gcc make openssl

Build

To build the DTLS server, run:

$ make && make -C tools

Usage

Run the DTLS server in the first terminal:

$ ./bin/dtlss 127.0.0.1 5684

On another terminal, run the command with OpenSSL:

$ echo "hallo\0" | openssl s_client -connect 127.0.0.1:5684 -dtls1_2 -msg -debug
