# cordon trust / untrust

> Manage the CA certificate in the system trust store.

## cordon trust

Add the proxy CA certificate to the system trust store so tools accept the proxy's TLS certificates.

```bash theme={null}
cordon trust [OPTIONS]
```

| Option           | Default                    | Description                                                                                 |
| ---------------- | -------------------------- | ------------------------------------------------------------------------------------------- |
| `--config`, `-c` | scope-resolved config path | Path to config file (to locate the CA cert). Mutually exclusive with `--scope`.             |
| `--scope`        | project                    | `project` or `user`; selects which config file to read. Mutually exclusive with `--config`. |

After running `cordon trust`, tools that read the system trust store will trust the proxy automatically.

<Note>
  Some runtimes do not use the system trust store. Use [`cordon env`](/cli/env) for app-specific CA variables and [SDK Compatibility](/guides/sdk-compatibility#runtime-ca-and-proxy-notes) for runtime-specific behavior.
</Note>

## cordon untrust

Remove the proxy CA certificate from the system trust store.

```bash theme={null}
cordon untrust [OPTIONS]
```

| Option           | Default                    | Description                                                                                 |
| ---------------- | -------------------------- | ------------------------------------------------------------------------------------------- |
