- All Implemented Interfaces:

,X509TrustManager
X509TrustManager
interface to support
SSL/TLS/DTLS connection sensitive trust management.
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.
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.

checkClientTrusted
public abstract 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 ofSSLSocket
, and the endpoint identification algorithm of theSSLParameters
is non-empty, to prevent man-in-the-middle attacks, the address that thesocket
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 ofSSLSocket
, and the algorithm constraints of theSSLParameters
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.- Parameters:
chain
- the peer certificate chainauthType
- the key exchange algorithm usedsocket
- the socket used for this connection. This parameter can be null, which indicates that implementations need not check the ssl parameters- Throws:
IllegalArgumentException
- if null or zero-length array is passed in for thechain
parameter or if null or zero-length string is passed in for theauthType
parameterCertificateException
- if the certificate chain is not trusted by this TrustManager- See Also:

checkServerTrusted
public abstract void checkServerTrusted(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 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.
If the
socket
parameter is an instance ofSSLSocket
, and the endpoint identification algorithm of theSSLParameters
is non-empty, to prevent man-in-the-middle attacks, the address that thesocket

chain
- the peer certificate chainauthType
- the key exchange algorithm usedsocket
- the socket used for this connection. This parameter can be null, which indicates that implementations need not check the ssl parameters- Throws:

For instance, if RSAPublicKey is used, the authType should be "RSA". Checking is case-sensitive.
If the
engine
parameter is available, and the endpoint identification algorithm of theSSLParameters
is non-empty, to prevent man-in-the-middle attacks, the address that theengine
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
engine

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 engine.- Parameters:
chain
- the peer certificate chainauthType
- the key exchange algorithm usedengine
- the engine used for this connection. This parameter can be null, which indicates that implementations need not check the ssl parameters- Throws:
