Email Alias Generator - HMAC de KJ

🚨 IMPORTANT: Cloudflare Worker Setup Required
This extension requires deploying a Cloudflare Worker to function. This is not a plug-and-play solution - you need your own custom domain and basic Cloudflare knowledge. If you're not comfortable with these requirements, this extension may not be suitable for you.

Key Features:

Lightweight: Minimal resource usage, fast performance

Easy Setup: Guided configuration with secure key generation and backup
Multiple Access Methods: Generate aliases via popup, context menu, or keyboard shortcuts
Real-time Feedback: Toast notifications for successful operations and errors

Deploy the open-source Cloudflare Worker to your account
Configure your custom domain in the extension settings
Generate a secure cryptographic key (safely backed up to your password manager)

Generate unique aliases on any website with just a few clicks

Technical Requirements:

A custom domain with catch-all email configured
Cloudflare account and basic knowledge of Workers
Ability to deploy and configure the provided Cloudflare Worker code

Security & Recovery:
The extension uses a "Key Ring Model" where your Cloudflare Worker can validate emails from multiple keys. If you lose your browser key, existing aliases continue working perfectly - simply generate a new key and add it to your Worker. No catastrophic failures, just minor inconvenience.
Perfect for:

Developers and tech-savvy users who want email privacy
Custom domain owners with catch-all email addresses
