  Modifier and Type	Method	Description
  void	checkClientTrusted(X509Certificate[] chain,String authType)	Given the partial or complete certificate chain provided by the peer, build a certificate path to a trusted root and return if it can be validated and is trusted for client SSL authentication based on the authentication type.
  void	checkServerTrusted(X509Certificate[] chain,String authType)	Given the partial or complete certificate chain provided by the peer, build a certificate path to a trusted root and return if it can be validated and is trusted for server SSL authentication based on the authentication type.
  X509Certificate[]	getAcceptedIssuers()	Return an array of certificate authority certificates which are trusted for authenticating peers.

• • Method Detail

     * #### checkClientTrusted  
     void checkClientTrusted([X509Certificate](../../../java/security/cert/X509Certificate.html "class in java.security.cert")[] chain,  
                             [String](../../../java/lang/String.html "class in java.lang") authType)  
                      throws [CertificateException](../../../java/security/cert/CertificateException.html "class in java.security.cert")  
     Given the partial or complete certificate chain provided by the peer, build a certificate path to a trusted root and return if it can be validated and is trusted for client SSL authentication based on the authentication type.  
      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.  
     Parameters:  
     `chain` \- the peer certificate chain  
     `authType` \- the authentication type based on the client certificate  
     Throws:  
     `[IllegalArgumentException](../../../java/lang/IllegalArgumentException.html "class in java.lang")` \- if null or zero-length chain is passed in for the chain parameter or if null or zero-length string is passed in for the authType parameter  
     `[CertificateException](../../../java/security/cert/CertificateException.html "class in java.security.cert")` \- if the certificate chain is not trusted by this TrustManager.  
     * #### checkServerTrusted  
     void checkServerTrusted([X509Certificate](../../../java/security/cert/X509Certificate.html "class in java.security.cert")[] chain,  
                             [String](../../../java/lang/String.html "class in java.lang") authType)  
                      throws [CertificateException](../../../java/security/cert/CertificateException.html "class in java.security.cert")  
     Given the partial or complete certificate chain provided by the peer, build a certificate path to a trusted root and return if it can be validated and is trusted for server SSL authentication based on the authentication type.  
      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.  
     Parameters:  
     `chain` \- the peer certificate chain  
     `authType` \- the key exchange algorithm used  
     Throws:  
     `[IllegalArgumentException](../../../java/lang/IllegalArgumentException.html "class in java.lang")` \- if null or zero-length chain is passed in for the chain parameter or if null or zero-length string is passed in for the authType parameter  
     `[CertificateException](../../../java/security/cert/CertificateException.html "class in java.security.cert")` \- if the certificate chain is not trusted by this TrustManager.  
     * #### getAcceptedIssuers  
     [X509Certificate](../../../java/security/cert/X509Certificate.html "class in java.security.cert")[] getAcceptedIssuers()  
     Return an array of certificate authority certificates which are trusted for authenticating peers.  
     Returns:  
     a non-null (possibly empty) array of acceptable CA issuer certificates.
