🛡️ Secure Paste

Never accidentally leak API keys, tokens, or credentials to AI chatbots again.

A browser extension that automatically detects and masks secrets when you paste code into AI platforms like ChatGPT, Claude, and Gemini.

🚀 Quick Start

1. Install the extension from Chrome Web Store
2. Paste your code into any AI platform
3. Relax - secrets are automatically masked

No configuration needed. Just install and go.

✨ Features

🔐 Automatic Secret Detection

• 33 Built-in Patterns: AWS keys, GitHub tokens, private keys, passwords, database URLs, and more
• Real-time Masking: Secrets masked instantly as you paste
• Smart Detection: Context-aware pattern matching prevents false positives

🔄 Secret Restoration

• Copy & Restore: Copy masked text and automatically restore original values
• AI-Safe Workflow: Paste masked → AI processes → Copy restored secrets
• Works Everywhere: Manual copy (Ctrl+C) and platform copy buttons

🎯 Supported Platforms

Pre-configured for popular AI platforms:

• ChatGPT (chatgpt.com)
• Claude (claude.ai)
• Google Gemini (gemini.google.com)
• Perplexity (www.perplexity.ai)
• Grok (grok.com)

⚙️ Customization

• 8 Category Toggles: Cloud keys, API tokens, private keys, passwords, database, network, PII, custom
• Custom Patterns: Add your own patterns for company-specific secrets
• Per-Site Control: Enable/disable protection for each site
• Usage Statistics: Track how many secrets you've protected

🎨 How It Works

Example

Before (what you copy):

const config = {
  awsAccessKey: 'AKIAIOSFODNN7EXAMPLE',
  githubToken: 'ghp_1234567890abcdefghijklmnopqrst',
  database: 'postgres://admin:secret@db.example.com/prod'
};

After (what AI sees):

const config = {
  awsAccessKey: '[AWS_KEY#a3f7]',
  githubToken: '[GITHUB_TOKEN#b2e9]',
  database: 'postgres://[USER#c4d1]:[PASS#e8f3]@[HOST#f9a2]/prod'
};

Restoration (when you copy back):

• Click copy button on AI response → Original secrets automatically restored
• Press Ctrl+C on masked text → Original secrets in clipboard
