`TLSA` adds a [TLSA certificate association record](https://www.rfc-editor.org/rfc/rfc6698) to a domain. The name should be the relative label for the record.

Usage, selector, and type are ints.

Certificate is a hex string.

{% code title="dnsconfig.js" %}
```javascript
D("example.com", REG_MY_PROVIDER, DnsProvider(DSP_MY_PROVIDER),
  // Create TLSA record for certificate used on TCP port 443
  TLSA("_443._tcp", 3, 1, 1, "abcdef0"),
);
```
{% endcode %}
