Whisper Mod

A client-side Fabric mod that improves private messaging in Minecraft. Send persistent DMs, start end-to-end encrypted sessions, and manage a friend list — all without leaving chat. No server installation required.

Installation

1. Install Fabric Loader
2. Download Fabric API and place it in your mods folder
3. Download the latest jar and place it in your mods folder
4. Launch Minecraft with the Fabric profile

Requirements

• Minecraft 26.1.2
• Fabric Loader 0.19.2+
• Fabric API 0.148.2+

Features

DM Sessions

Start a persistent DM session with /wm dm <player> — every message you type is automatically sent as a whisper. No more retyping /w every time. Messages from friends show a ★ indicator.

Encrypted Messaging

Use /wm em <player> to request an end-to-end encrypted session. Once both players accept, all messages are encrypted using ECDH key exchange + AES-CBC. Nobody else can read them — not even the server.

Friend System

Add friends, manage requests, and control who can contact you. EM sessions require both players to be friends first.

• Friend and EM requests arrive as clickable [Accept] / [Decline] buttons in chat
• Friend requests expire after 60 seconds with no response
• Friend lists are stored locally in .minecraft/config/whispermod/

Block System

Block players from sending you friend or EM requests. Blocking a friend automatically unfriends them and notifies both sides. Players are notified when they try to contact someone who has blocked them.

Consistent UI

All mod notifications appear under a [WM] purple tag. Encrypted messages use [EM] in green. DMs use [DM] in yellow. Everything is color coded — green for good news, red for bad news.

Commands

Command Description /wm dm <player> Start an unencrypted DM session /wm em <player> Send an encrypted session request (friends only) /wm friend <player> Send a friend request /wm unfriend <player> Remove a friend (notifies them, must be online) /wm friends View your friend list /wm pending View pending outgoing friend requests /wm block <player> Block someone from sending you requests (must be online) /wm unblock <player> Unblock someone (notifies them) /wm back Return to public chat /wm help List all commands with clickable shortcuts

/whispermod works as an alias for /wm

Note: Encrypted sessions (/wm em) require both players to have the mod installed and be friends.

Note: Unfriending and blocking only work when the target is online so they can be notified.

Warning: Friend and block lists are stored locally in .minecraft/config/whispermod/. Deleting this folder, reinstalling the mod, or switching computers will reset all your friends and blocked players — which will break it for other people who have you friended.
