*** ** * ** ***

This class is the base interface for hostname verification.

During handshaking, the verification mechanism can call back to implementers of this interface to determine if this connection should be allowed.

For more information of the use of this interface on Android, see[HttpsURLConnection.setDefaultHostnameVerifier(HostnameVerifier)](https://developer.android.com/reference/javax/net/ssl/HttpsURLConnection#setDefaultHostnameVerifier(javax.net.ssl.HostnameVerifier)).

The policies can be certificate-based or may depend on other authentication schemes.
