🛡️ [GHAS 1021] Stop Secrets While Using Codespaces

Standard: GitHub Advanced Security (GHAS) Enforcement
Project: Secure-Lab-Environment v5.3

📋 Overview

Leaking API keys, tokens, or credentials in a public repository is one of the highest risks in Digital Archaeology. GHAS 1021 establishes the protocol for using GitHub Codespaces as a "Clean Room" environment, ensuring that secrets never touch the git history.

🚨 The Risk: Why Standard Env Vars Aren't Enough

When working in a Codespace, developers often hardcode secrets into scripts or .env files. If these files are accidentally staged and committed, the secret is permanently etched into the repository's history.

---

🛠️ The Solution: Codespace Secret Management

Instead of local files, use the integrated Codespace Secrets vault. This ensures secrets are injected as Environment Variables at runtime but remain invisible to the codebase.

1. Configuration Path

1. Navigate to your repository Settings.
2. Select Secrets and variables > Codespaces.
3. Add your secret (e.g., (API_KEY).
4. Select the repository access.

2. Accessing Secrets in Python

Once configured in GitHub, your code should access the secret via the os module. Never define the string value in your script.

import os

# DO NOT: api_key = "12345-SUPER-SECRET"
# DO: Use the GHAS 1021 Standard
def get_lab_connection():
    api_key = os.getenv('API_KEY')
    
    if not api_key:
        raise EnvironmentError("GHAS 1021 Violation: API_KEY not found in environment.")
        
    return f"Authenticated with {api_key[:4]}****"
