Secrets Management

This walks you through integrating Vault, AWS Secrets Manager, or cloud-native options into your CI/CD pipelines so you stop hardcoding credentials. It covers GitHub Actions and GitLab CI examples, secret rotation patterns, and tools like External Secrets Operator for Kubernetes. The pre-commit hook examples using TruffleHog are practical for catching leaks before they hit your repo. If you're moving from environment variables scattered across deployment configs to actual secrets management, this gives you working snippets for the major platforms. The safety reminders around masking and least-privilege access are obvious but worth repeating since this is the infrastructure that protects everything else.
