A web application that scans websites for potential API keys, secrets, and sensitive information leaks. This tool helps developers and security professionals identify and fix security vulnerabilities in their web applications.

Referenced Project: Key detection patterns inspired by Keyleaksecret.

• Scans web pages for common secret patterns (API keys, passwords, tokens, etc.)
• Checks response headers for sensitive information
• Validates security headers
• User-friendly web interface
• Real-time scanning results
• Categorizes findings by severity

1. Clone this repository:

   git clone <repository-url>
   cd keyleak-detector

2. Create and activate a virtual environment (recommended):

   python -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install the required dependencies:

   pip install -r requirements.txt

4. Install Playwright browsers (required for scanning):

   playwright install chromium
   playwright install-deps

1. Start the application:

2. Open your web browser and navigate to:

   Note: The app runs on port 5002 instead of 5000 as port 5000 is commonly used by AirPlay on macOS.

3. Enter the URL you want to scan in the input field and click "Scan Now"

4. View the results, which will show any potential security issues found

The application uses a combination of browser automation and network traffic analysis to find secrets:

1. Browser Automation: Uses Playwright to load the target website in a headless browser
2. Network Monitoring: Intercepts HTTP requests and responses using mitmproxy
3. Content Analysis: Analyzes JavaScript, HTML, headers, and dynamic content
4. Pattern Matching: Uses regex patterns to detect various types of secrets
5. Smart Filtering: Filters false positives using context-aware analysis
6. Categorization: Groups findings by severity (Critical, High, Medium, Low)

The scanner detects 50+ types of sensitive information including:

Cloud Provider Credentials:

• AWS Access Keys & Secret Keys
• Google API Keys & OAuth Tokens
• Google Cloud Service Account Keys
• Google Vertex AI API Keys
• Firebase API Keys
• Heroku API Keys

Service Credentials:

• Stripe API Keys
• Slack Tokens
• GitHub Tokens & OAuth
• GitLab Tokens
• Mailgun, Mailchimp, Twilio API Keys
• npm Tokens

LLM/AI Inference Provider Keys:

• OpenAI API Keys (GPT-4, ChatGPT, etc.)
• Anthropic API Keys (Claude)
• Google Gemini & Vertex AI API Keys
• Hugging Face Tokens
• Cohere API Keys
• OpenRouter API Keys
• Replicate API Keys
• Together AI API Keys
• Perplexity AI API Keys
• Mistral AI API Keys
• AI21 Labs API Keys
• Anyscale API Keys
• DeepInfra API Keys
• Groq API Keys
• Fireworks AI API Keys

Database Credentials:

• MongoDB, PostgreSQL, MySQL, Redis connection strings
• SQL Server connection strings

Authentication:

• JWT Tokens
• Bearer Tokens
• OAuth Tokens
• Session Tokens
• Basic Auth credentials
• API Keys

Sensitive Data:

• Private SSH Keys
• Credit Card Numbers
• Social Security Numbers
• Email Addresses
• Phone Numbers

Other:

• Webhook URLs
• Callback URLs
• Hardcoded passwords
• Encrypted credentials in JavaScript

When the scanner detects potential secrets, it provides:

• Severity classification (Critical, High, Medium, Low)
• Context information showing where the secret was found
• Actionable recommendations for remediation
• Best practices for secure credential management
