ModSync

# ModSync ## Why should you use ModSync? ModSync is a client-server setup that adds transparency to the client's Mods and Texture packs. Here are more ways ModSync might turn out helpful: - **Anti-Cheat:** Instead of the server running continuous checks for cheats, ModSync presents a 1 time check solution. ModSync doesn't just check your mod directory; It checks all the threads running inside Minecraft. - **Auto-Authorisation:** No need for fancy auth plugins, ModSync generates a unique authorisation key for every device. This will link with the player's username once he joins the server. If someone with a different key tries to log in with the user's account, ModSync will kick them for a mismatched auth key. - **Modlist & Packlist:** All the Mods and Texture packs installed on the client will be listed in the username's log file. - **Screenshot Player's Gamescreen:** Admins can use a command to take a screenshot of screenshots of players gamescreen to ensure texture pack legitimacy. (mainly used to detect Xray packs) ## 🛡️ Core Security ModSync doesn't just "ask" the client for a list; it uses a secure challenge-response handshake: **Dynamic Hashing:** Every handshake is secured with SHA-512 using a server-side pepper and a unique challenge UUID to prevent packet spoofing. **Privacy-First:** Players are prompted to agree to data reporting on their first join, ensuring compliance with privacy standards. ## ⚙️ Technical Features **Categorized Resource Reporting:** Unlike basic list-reporters, ModSync distinguishes between Active (enabled), Inactive (in folder), and Deleted resource packs. **Intelligent Mod Consolidation:** Automatically collapses library dependencies (like fabric-api sub-modules) into single entries to keep admin modlists readable. **Historical Audit Logs:** Every player gets a dedicated .yml log tracking their mod/pack history across sessions—including timestamps of when a mod was removed. **Remote Diagnostics:** Admins can request remote screenshots or even "dump" specific mod/pack files directly from a client to verify suspicious files. **Bedrock Support:** Native compatibility with Geyser/Floodgate to skip verification for Bedrock players while maintaining strict security for Java players. ## 💻 Commands _**/modsync modlist <player>**_ – View all installed mods (filtered to remove library noise). _**/modsync packlist <player>**_ – View active vs. inactive resource packs. _**/modsync screenshot <player>**_ – Request a secure remote screenshot. _**/modsync dump <player> <mod|pack> <id>**_ – Download a specific file from the player's client for inspection. _**/modsync authreset <player>**_ – Reset the hardware ID link for a player. _**/modsync reload**_ – Hot-reload all configurations and banned/required lists. ## 🚀 Setup 1. Install the **Plugin** on your Spigot/Paper server. 2. Install the **Mod** on your Fabric client. 3. Configure your **_required-mods_** and banned-mods in the server's **_config.yml_**. _Developed by Dark_Yoddha — Built for Integrity._
