Discord Encryption

We're back baby :)

An experimental encryption solution for Discord using BetterDiscord.

Download the encryption.plugin.js from the releases here.

Features ⚡

Adds ability to encrypt / decrypt messages on discord using a set password

• Utilizes AES-GCM (Advanced Encryption Standard in Galois/Counter Mode) via native Web Crypto API
• Passwords are saved per-chat
• Messages are decrypted the moment they are receved with little to no delay
• Encrypted messages appear as green
• Messages that fail to be decrypted (most likely due to an incorrect password) will be highlighted red

How to use

Install

• Install Discord
• Install BetterDiscord
• Navigate to Discord Preferences -> BD/Plugins -> Open Plugin Folder
• Place 'encryption.plugin.js' in BetterDiscord's plugin folder
• Enable encryption in the BD/Plugins preference pane.

It may ask to install an additional plugin 0PluginLibrary.plugin which is required - It should install itself if you click download.

Usage

• To toggle the encryption simply click the lock icon. You will be prompted for a password, if none is found for the chat channel.
• Received messages are decrypted automatically
• To view or change the encryption password simply right-click the lock icon and an input box will appear - passwords are automatically saved as you type

Development

This plugin uses rolldown to bundle what's in src into the final encryption.plugin.js script.

Getting rolldown to work with BetterDiscord was a gamechanger as it allows the plugin to use multiple src files instead of just one. This makes development much nicer.

How to build Build:

$ yarn && yarn build

This runs both rolldown, and a build-patch script to add the required BetterDiscord META tags.
