After 5 Years of Coding, I Realized True Secret Protection Comes From Environment Variables, Not Encryption

Hard‑coding secrets in source code or config files creates maintenance headaches and security risks, whereas using environment variables—following the 12‑Factor App principle—decouples configuration, improves security, and enables dynamic, painless updates without rebuilding the application.
