getSecret

Retrieves a secret value from environment variables.

SECURITY NOTICE: Secrets are returned as Strings because the underlying OS APIs (environment variables, system properties) return Strings. The String cannot be cleared from memory.

Best practices:

• Use platform-specific secure storage when possible (Keychain, KeyStore)

• Use short-lived tokens instead of long-lived secrets

• Rotate secrets regularly

• Don't log or print secret values

For maximum security, consider using:

• Secrets management services (HashiCorp Vault, AWS Secrets Manager)

• Platform secure storage APIs

• Memory-mapped files with OS-level protection
