## Get HwId

### Dependencies

```bash
npm install child_process
```

```javascript
const { execSync } = require("child_process");

function getHwId() {
    const platforms = {
        win32: [
            "REG QUERY HKLM\\SOFTWARE\\Microsoft\\Cryptography /v MachineGuid",
            /MachineGuid\s+REG_SZ\s+(.*?)\s/
        ],
        darwin: [
            "ioreg -rd1 -c IOPlatformExpertDevice",
            /"IOPlatformUUID" = "(.*?)"/
        ],
        linux: [
            "cat /var/lib/dbus/machine-id /etc/machine-id 2> /dev/null || true",
            /^([\da-f]+)/
        ]
    }

    const getPlatform = platforms[process.platform];
    if (!getPlatform) return;
    const result = getPlatform[1].exec(execSync(getPlatform[0]).toString());
    if (!result) return;
    return result[1] || undefined;
};
