Avant Let's Encrypt, ces certificats HTTPS étaient vendus par des tiers de confiance.

Le processus d'acquisition d'un de ces certificats était auparavant lourd, nécessitait pas mal de paperasses et les certificats étaient assez chers.

Mais ensuite, <a href="https://letsencrypt.org/" class="external-link" target="_blank">Let's Encrypt</a> a été créé.

      val rule = publicSuffixList.bytes.binarySearch(domainLabelsUtf8Bytes, i)
      if (rule != null) {
        exactMatch = rule
        break
      }
    }

    // In theory, wildcard rules are not restricted to having the wildcard in the leftmost position.
    // In practice, wildcards are always in the leftmost position. For now, this implementation

You could also define it as a normal function instead of `async def`:

/// note

If you don't know the difference, check the [Async: *"In a hurry?"*](../async.md#in-a-hurry){.internal-link target=_blank}.
