🤝 HandShaker 6.0.0 (Beta)

Neo Forge

📋 What is HandShaker?

HandShaker is a cross-platform mod/plugin verification system for Minecraft servers and clients. It enables servers to detect which mods players are running and enforce mod restrictions with customizable policies.

🎯 Core Functionality

Fabric/Neoforge Client → Sends your active mod list to the server upon join
Paper/Fabric/NeoForge Server → Validates mod lists against configured rules and enforces restrictions
Multi-platform Support → Works across Fabric, Paper, and NeoForge
Cryptographic Integrity → Prevents tampered or self-compiled HandShaker mods
Flexible Configuration → Per-mod rules: Required, Allowed, or Blacklisted

✨ Key Features

Feature	Description
🔐 Per-Mod Configuration	Individually set mod allowance to Required, Allowed, or Blacklisted
🚫 Customizable Enforcement	Configurable kick messages and auto-ban capabilities
📊 Player History Database	Store and query player mod histories
👀 Player Mod Viewing	Administrators can see other players' mod lists
✔️ Integrity Verification	Cryptographic signatures prevent spoofed mod reports
🔐 Custom Actions	Allows to setup custom events (commands) for triggered mods
