Whisper Mod

Whisper Mod started as a simple quality-of-life mod to avoid retyping /w every message, and grew into a full private messaging system with end-to-end encryption, a friend system, and a block system — all running entirely on the client side.

Note: Whisper Mod currently requires the server to have the EssentialsX plugin installed.

Features

DM Sessions

Start a persistent DM session with /wm dm <player> — every message you type is automatically sent as a whisper. Messages from friends show a ★ indicator.

Reply System

Receive a whisper from someone outside your session and clickable [Reply] and [Start Session] buttons appear in chat. Reply sends a single whisper without starting a session. The HUD shows [Re to player] while replying and clears automatically after sending.

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. The session ends automatically if either player disconnects.

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 with sound effects
Friend requests expire after 60 seconds, EM requests after 30 seconds
Get notified when a friend is online on your server or leaves
Check who's online with /wm status
⚠️ Friend lists are stored locally in .minecraft/config/whispermod/ — reinstalling the mod or switching computers will reset them, which will break it for others who have you friended

Block & Mute System

Block — prevents someone from sending you friend or EM requests, and notifies them
Mute — silently ignores friend and EM requests from a player or everyone, they have no idea

Notes

/whispermod works as an alias for /wm
Encrypted sessions require both players to have the mod installed and be friends
Unfriending and blocking only work when the target is online so they can be notified
