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 does not require such checks, but some protocols
over TLS (such as HTTPS) do. In earlier versions of the JDK, the
certificate chain checks were done at the SSL/TLS layer, and the hostname
verification checks were done at the layer over TLS. This class allows
for the checking to be done during a single call to this class.
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.

 abstract public void checkClientTrusted(X509Certificate[] chain,
String authType,
Socket socket) throws CertificateException
Given the partial or complete certificate chain provided by the
peer, build and validate the certificate path based on the
authentication type and ssl parameters.
The authentication type is determined by the actual certificate
used. For instance, if RSAPublicKey is used, the authType
should be "RSA". Checking is case-sensitive.
If the socket parameter is an instance of
javax.net.ssl.SSLSocket , and the endpoint identification
algorithm of the SSLParameters is non-empty, to prevent
man-in-the-middle attacks, the address that the socket
connected to should be checked against the peer's identity presented
in the end-entity X509 certificate, as specified in the endpoint
identification algorithm.
If the socket parameter is an instance of
javax.net.ssl.SSLSocket , and the algorithm constraints of the
SSLParameters is non-null, for every certificate in the
certification path, fields such as subject public key, the signature
algorithm, key usage, extended key usage, etc. need to conform to the
algorithm constraints in place on this socket. |

Socket socket) throws CertificateException Given the partial or complete certificate chain provided by the

The authentication type is the key exchange algorithm portion
of the cipher suites represented as a String, such as "RSA",
"DHE_DSS". Note: for some exportable cipher suites, the key
exchange algorithm is determined at run time during the
handshake. For instance, for TLS_RSA_EXPORT_WITH_RC4_40_MD5,
the authType should be RSA_EXPORT when an ephemeral RSA key is
used for the key exchange, and RSA when the key from the server
certificate is used. Checking is case-sensitive.
