• Discord service configured in Alliance Auth (bot and guild)

Installation

Install the app in your AA virtual environment:

pip install aa-discord-obfuscate

Add the app to your AA INSTALLED_APPS in settings/local.py:

INSTALLED_APPS += [
    "discord_obfuscate",
]

Run migrations and restart AA:

python manage.py migrate

Configuration

App Settings (settings/local.py)

Only one optional setting is supported in settings/local.py:

# Discord Obfuscate
DISCORD_OBFUSCATE_SECRET = "change-me"  # Defaults to SECRET_KEY

All other behavior is configured in Django admin.

---

Initial Configuration (First Run)

Complete these steps before syncing roles for the first time:

1. In Django admin, open Discord Obfuscate Config and set your defaults.

   • Highly recommended: enable Default opt-out so new entries keep the original group name until you explicitly opt in to obfuscation.
   • Set the default obfuscation type, divider characters, and min chars if you want a consistent output format from day one.

2. Open Discord Role Order Config, select the bot role in the dropdown, and save.

   • This dropdown is populated from live Discord role data.
   • Saving after the bot role is set ensures the role ordering page can correctly lock roles above the bot.

3. Open Discord Role Obfuscations.

   • Use the admin action dropdown Discover groups from Discord roles to pull current Discord roles into per-group entries.
   • Use the bulk action Toggle opt-out for selected roles to opt in/out the groups you want to obfuscate.

4. Run a sync:

   • Use Sync selected roles now or Sync all roles now, or rely on sync-on-save if enabled. Additionally, you can wait for the periodic task.

---

Enable and Schedule Tasks

The app ships periodic tasks, but they only run when enabled

1. Create the periodic tasks:

python manage.py obfuscate_setup

2. In Django admin, open Discord Obfuscate Config and enable the task toggles you need: Periodic sync, Role color rule sync, and/or Random key rotation.

This creates three periodic tasks in Periodic Tasks disabled by default:

• Obfuscate Discord: Sync all roles (hourly)
• Obfuscate Discord: Sync role colors (hourly)
• Obfuscate Discord: Rotate random keys (every 3 days)

You can adjust schedules in Django admin under Periodic Tasks.

Default Settings

Use the Discord Obfuscate Config in Django admin to control defaults for newly created per-group entries:

• Sync on save queues a rename task when you save a per-group config. (recommended)
• Default opt-out sets new entries to keep the original group name.
• Default use random key turns on random-key mode by default.
• Default rotate name controls the random key rotation behavior.
• Default obfuscation type chooses the hashing method for new entries.
• Default divider characters and Default min chars before divider set output formatting defaults.
• Random key rotation enabled periodically changes the random key used for random key input, and therefore changes the name of the obfuscated roles.
• Role ordering is configured in Discord Role Order Config (separate admin menu).
• Require existing role controls whether the Discord service is allowed to create a missing role when neither the original nor obfuscated role exists.
• Role color rule sync enabled and Periodic sync enabled gate their respective tasks.

Defaults are applied when entries are created.

Usage

Per-Group Obfuscation

1. Go to Discord Role Obfuscations in Django admin.
2. Use the Discover groups from Discord roles action to create entries for roles that already exist in Discord, or add entries manually (recommended).
3. Configure per-group options:
   • Opt out to keep the original group name.
   • Custom name override (takes precedence over hashing).
   • Random key mode plus rotate-name flag.
   • Obfuscation method, format, divider characters, and min chars per divider.
   • Optional fixed role color (#RRGGBB).
4. Use the preview field to verify the output name.
5. Use the admin actions Sync selected roles now or Sync all roles now, or rely on sync-on-save (recommended) / periodic sync.

Obfuscation Process

When the Discord service requests group names, the app intercepts and computes the desired role name for each group:

1. If Opt out is enabled, the original group name is used.
2. If Custom name is set, that value is sanitized and used.
3. Otherwise, the input is the group name or the random key (if enabled).
4. The input is hashed with HMAC using DISCORD_OBFUSCATE_SECRET and the selected method (SHA256/BLAKE2s with hex/base32 encoding).
5. The output is formatted with the per-group format (or {hash12}), sanitized to allowed characters, dividers inserted (if configured), and truncated to 100 characters.

When a sync runs, the app:

• Finds an existing Discord role by desired name, cached role ID, last obfuscated name, or original group name.
• Renames the role to the desired obfuscated name.
• Applies the per-group role color if set.

Random Key Rotation

Enable Use random key on a per-group basis to generate a 16-character alphanumeric key that replaces the group name for obfuscation input. When the random-key rotation task is enabled in Discord Obfuscate config, it will:

• Rotate keys for entries with Use random key enabled.
• Rename those roles to the newly obfuscated names.
• Apply the manual role order configuration if it is enabled.

Each random-key entry can opt out of renaming via the rotate-name checkbox shown when Use random key is enabled. Manual ordering is configured in Discord Role Order Config; locked roles remain fixed while unlocked roles may be shuffled when the rotation task runs.

Role Ordering

Role ordering is configured in Discord Role Order Config.

• Set the bot role in the dropdown and save. Roles above the bot are locked.
• The table shows live Discord role order; to change order, edit roles in Discord and refresh this page.
• Lock checkboxes only affect automation when role ordering is enabled.
• Opt-out and color are read-only here. Update opt-out in Discord Role Obfuscations and color in Discord or via Role Color Rules.

Role Coloring

There are two ways to color roles. Per-group colors always take precedence.

Per-group fixed color:

• Set Role color on a Discord Role Obfuscation entry (#RRGGBB).
• The next sync applies that color when renaming, even if the name already matches.
• Roles with a fixed color are treated as pinned and are skipped by rule-based colors. Run a sync after setting a fixed color so the role ID is cached.

Rule-based random colors:

1. Create one or more Discord Role Color Rules with a name pattern (use * as the wildcard), optional case sensitivity, and a priority (lower numbers run first).
2. Enable Role color rule sync in Discord Obfuscate Config.
3. Enable the task in Periodic Tasks.

When the rule sync task runs, it:

• Scans all Discord roles and existing color assignments.
• Skips roles that already have a color, are pinned by per-group settings, or already have an assignment.
• Builds a 250-color palette and chooses a random unused color for each match.
• Updates the role in Discord and stores a Discord Role Color Assignment.
• Keeps assignments stable and cleans up stale ones if roles disappear.

Limitations

• State-based role mapping is not supported. The Alliance Auth Discord service passes a state_name argument, but this app ignores it and only uses group memberships.

Uninstall / Reset

If you want to fully remove this app and all of its data, do the following:

0. Reset role names (recommended)

• Set the obfuscation entry to opt-out for each group so the original group name is used, then run a sync to rename roles back to their defaults. (or save if you use update on save)

1. Stop services

• Stop the Celery worker/beat so no tasks run during cleanup.

2. Disable scheduled tasks (optional but recommended)

• In Django admin (django_celery_beat), delete periodic tasks named:
  • Obfuscate Discord: Sync all roles
  • Obfuscate Discord: Sync role colors
  • Obfuscate Discord: Rotate random keys

3. Remove database tables

• Run:

python manage.py migrate discord_obfuscate zero

This drops all discord_obfuscate tables and data.

4. Remove the app from settings

• Remove discord_obfuscate from INSTALLED_APPS.

5. Delete code

• Uninstall the package or remove the app directory, then restart Alliance Auth.

If you want to reset without uninstalling:

• Run step 3 only, then re‑run:

python manage.py migrate

This recreates empty tables with a clean state.
