Best Practices

1. Never Commit Secrets

```bash

.gitignore

.env .env.local *.pem _secret ```

2. Use Environment Variables

```typescript // Good - from environment const apiKey = process.env.API_KEY;

// Bad - hardcoded const apiKey = 'sk-1234567890'; ```

3. Rotate Regularly

```typescript // Implement rotation-aware code async function getDbConnection() { const credentials = await secretsManager.getSecret('db-credentials'); return createConnection(credentials); } ```
