Overview

The profile.yaml file is located in the same directory as the justserver binary (typically dist/). It defines all server parameters including network configuration, authentication, TLS, and plugin loading.

SSL/TLS Setup

Quick Start

Use the included script to generate a self-signed certificate:

cd dist
bash ssl_gen.sh

This runs:

openssl req -x509 -nodes -newkey rsa:2048 \
 -keyout server.rsa.key -out server.rsa.crt -days 3650

You’ll be prompted for certificate details (country, organization, common name, etc.). For quick testing, you can press Enter to accept defaults.

HTTP Server Configuration

Error Response Configuration

When the server receives a request that doesn’t match any registered endpoint or fails authentication, it returns a configurable error response. This is critical for OPSEC — the error page should look like a legitimate web server.
