Hidder 📂

Hidder is a Fabric mod designed to work in tandem with the ModSeeker Paper plugin. It provides secure client-side mod verification, detailed system reporting, and encrypted communication with servers running ModSeeker.

✨ Features

  • Client-Side Only: Runs exclusively on the client; no server-side operations.
  • Comprehensive Mod Detection: Detects all installed Fabric mods with version information.
  • Resource Pack Detection: Detects folder-based and ZIP-based resource packs.
  • Shader Pack Detection: Detects installed shaders.
  • Secure Communication: Encrypted channels for mod verification with ModSeeker.
  • Native Cryptography: Uses a native C++ library for RSA/AES encryption and digital signatures.
  • Replay Attack Protection: Includes timestamps in all signed messages.
  • System Info Reporting: Sends OS, Java, Minecraft, and Fabric versions to the server.

🛠 Requirements

  • Minecraft 1.21.10
  • Fabric Loader 0.17.2 or higher
  • Fabric API
  • Java 21 or higher
  • Compatible server running ModSeeker

📦 Installation

  1. Install Fabric Loader for Minecraft 1.21.10.
  2. Download the latest Hidder.jar release.
  3. Place the JAR in your mods/ folder.
  4. Launch the game.

🔗 How It Works

Connection Process

  1. Presence Announcement: Hidder announces itself to the server running ModSeeker.
  2. Handshake: Waits for server acknowledgment.
  3. Mod List Provision: Responds with a full mod list and system info when requested.
  4. Encryption: All communication is encrypted using hybrid RSA/AES.

Communication Protocol

Hidder uses a custom plugin-channel protocol to communicate with ModSeeker:

Message Type Description
ANNOUNCE_PRESENCE Declares Hidder is installed on the client.
ACKNOWLEDGE_PRESENCE Server confirms receipt of announcement.
REQUEST_MODLIST Server requests the client's mod list.
RESPONSE_MODLIST Client responds with mod list and system info.

🔒 Security Implementation

  • Native Vault: Uses hidder_vault.dll (Windows) / .so (Linux) for cryptographic operations.
  • Hybrid Encryption: RSA public-key encryption secures AES session keys; AES-CBC encrypts payloads.
  • Digital Signatures: Messages are signed to prevent tampering.
  • Replay Protection: Timestamps included in all signed messages.
  • Payload Verification: Server validates signatures and timestamps before accepting data.
