Secret detection test — handling placeholder secrets safely

You included a code snippet that contains placeholder secrets. That's safe, but be careful: do not paste real API keys, passwords, or cloud credentials into public forums or shared logs.

Recommendations:

• Replace placeholders with environment variables at runtime rather than hard-coding values in source files. Example pattern (Python):
  • Set environment variables in your deployment environment or a secrets manager.
  • Access them in code: API_KEY = os.environ.get("API_KEY")
• Use a secrets manager (AWS Secrets Manager, HashiCorp Vault, GitHub Secrets, etc.) for production credentials.
• Add secret scanning to your CI (GitGuardian, truffleHog, GitHub secret scanning).
• If you accidentally commit real credentials to a public repo, immediately rotate/disable them and remove the secret from the history (git filter-repo or BFG) and any caches.

If you want, I can:

• Show a small secure example of reading secrets from environment variables in Python.
• Suggest CI tools or a checklist for removing leaked secrets. Which would you prefer?
