 *  New: `HandshakeCertificates.Builder.addInsecureHost()` makes it easy to turn off security in
    private development environments that only carry test data. Prefer this over creating an
    all-trusting `TrustManager` because only hosts on the allowlist are insecure. From
    [our DevServer sample][dev_server]:

    ```kotlin
    val clientCertificates = HandshakeCertificates.Builder()
        .addPlatformTrustedCertificates()

  }

  private fun enableTls() {
    client =
      client
        .newBuilder()
        .sslSocketFactory(
          handshakeCertificates.sslSocketFactory(),
          handshakeCertificates.trustManager,
        ).hostnameVerifier(RecordingHostnameVerifier())
        .build()
    server.useHttps(handshakeCertificates.sslSocketFactory())
  }

  private inner class DelayedRequestBody(

          },
        ).addNetworkInterceptor(networkInterceptor)
        .addInterceptor(applicationInterceptor)
        .sslSocketFactory(
          handshakeCertificates.sslSocketFactory(),
          handshakeCertificates.trustManager,
        ).hostnameVerifier(hostnameVerifier)
        .build()
    host = "${server.hostName}:${server.port}"
    url = server.url("/")
  }

  @Test
  fun levelGetter() {
    // The default is NONE.

  private fun enableTlsWithTunnel() {
    client =
      client
        .newBuilder()
        .sslSocketFactory(
          handshakeCertificates.sslSocketFactory(),
          handshakeCertificates.trustManager,
        ).hostnameVerifier(RecordingHostnameVerifier())
        .build()
    server.useHttps(handshakeCertificates.sslSocketFactory())
  }

 *  New: Accept user-provided trust managers in `OkHttpClient.Builder`. This
    allows OkHttp to satisfy its TLS requirements directly. Otherwise OkHttp
    will use reflection to extract the `TrustManager` from the
    `SSLSocketFactory`.
 *  New: Support prerelease Java 9. This gets ALPN from the platform rather than
    relying on the alpn-boot bootclasspath override.
