== Why is this an issue?

include::../description.adoc[]

=== Noncompliant code example

When using the https://square.github.io/okhttp/4.x/okhttp/okhttp3/-ok-http-client/-builder/hostname-verifier/[okhttp library], a custom unsecure hostname verifier accepting every hostname is used:

[source,kotlin]
----
val builder = OkHttpClient.Builder()
builder.hostnameVerifier(object : HostnameVerifier {
  override fun verify(hostname: String?, session: SSLSession?): Boolean {
    return true // Noncompliant (s5527)
  }
})
----

=== Compliant solution

When using the https://square.github.io/okhttp/4.x/okhttp/okhttp3/-ok-http-client/-builder/hostname-verifier/[okhttp library], if ``++hostnameVerifier++`` method is not used to set a verifier, then a built-in secure one will be used:

[source,kotlin]
----
val builder = OkHttpClient.Builder()
