## How to retrieve sensitives

### JavaScript API
Use `humanenv.get('key')` inside your application. The returned value must be used immediately and then set to `null` to prevent memory leaks.

### CLI
Use humanenv CLI to retrieve envs. Do not attempt to log or dump all envs.

## Rules
1. NEVER log env values retrieved from humanenv
2. NEVER dump or export multiple values at once
3. ALWAYS null variables after use
4. NEVER write sensitives to files
5. Do not generate scripts that use humanenv in loops or to exfiltrate data
