/**
 * Extensions to the {@code X509TrustManager} interface to support
 * SSL/TLS/DTLS connection sensitive trust management.
 * <p>
 * To prevent man-in-the-middle attacks, hostname checks can be done
 * to verify that the hostname in an end-entity certificate matches the
 * targeted hostname.  TLS/DTLS does not require such checks, but some
 * protocols over TLS/DTLS (such as HTTPS) do.  In earlier versions of the
 * JDK, the certificate chain checks were done at the SSL/TLS/DTLS layer,
 * and the hostname verification checks were done at the layer over TLS/DTLS.
 * This class allows for the checking to be done during a single call to
 * this class.
 * <p>
 * RFC 2830 defines the server identification specification for the "LDAPS"
 * algorithm. RFC 2818 defines both the server identification and the
 * client identification specification for the "HTTPS" algorithm.
