Class TrustManagerFactory

java.lang.Object
  |
  +--com.sun.net.ssl.TrustManagerFactory

public class TrustManagerFactory

extends Object

This class acts as a factory for trust managers based on a source of trust material. Each trust manager manages a specific type of trust material for use by secure sockets. The trust material is based on a KeyStore and/or provider specific sources.

Constructor Summary

protected

TrustManagerFactory(TrustManagerFactorySpi factorySpi, Provider provider, String algorithm) Creates a TrustManagerFactory object.

Method Summary

String	getAlgorithm() Returns the algorithm name of this TrustManagerFactory object.
static String	getDefaultAlgorithm() The default TrustManager can be changed by setting the value of the "sun.ssl.trustmanager.type" security property (in the Java security properties file) to the desired name.
static TrustManagerFactory	getInstance(String algorithm) Generates a TrustManagerFactory object that implements the specified trust management algorithm.
static TrustManagerFactory	getInstance(String algorithm, Provider provider) Generates a TrustManagerFactory object for the specified trust management algorithm from the specified provider.
static TrustManagerFactory	getInstance(String algorithm, String provider) Generates a TrustManagerFactory object for the specified trust management algorithm from the specified provider.
Provider	getProvider() Returns the provider of this TrustManagerFactory object.
TrustManager[]	getTrustManagers() Returns one trust manager for each type of trust material.
void	init(KeyStore ks) Initializes this factory with a source of certificate authorities and related trust material.

Constructor Detail

TrustManagerFactory

protected TrustManagerFactory(TrustManagerFactorySpi factorySpi,
                              Provider provider,
                              String algorithm)

Creates a TrustManagerFactory object.

Parameters:

factorySpi - the delegate

provider - the provider

algorithm - the algorithm

Method Detail

getDefaultAlgorithm

public static final String getDefaultAlgorithm()

The default TrustManager can be changed by setting the value of the "sun.ssl.trustmanager.type" security property (in the Java security properties file) to the desired name.

Returns:

the default type as specified in the Java security properties file, or an implementation-specific default if no such property exists.

getAlgorithm

public final String getAlgorithm()

Returns the algorithm name of this TrustManagerFactory object.

This is the same name that was specified in one of the getInstance calls that created this TrustManagerFactory object.

Returns:

the algorithm name of this TrustManagerFactory object.

getInstance

public static final TrustManagerFactory getInstance(String algorithm)
                                             throws NoSuchAlgorithmException

Generates a TrustManagerFactory object that implements the specified trust management algorithm. If the default provider package provides an implementation of the requested trust management algorithm, an instance of TrustManagerFactory containing that implementation is returned. If the algorithm is not available in the default provider package, other provider packages are searched.

Parameters:

algorithm - the standard name of the requested trust management algorithm.

Returns:

the new TrustManagerFactory object

Throws:

NoSuchAlgorithmException - if the specified algorithm is not available in the default provider package or any of the other provider packages that were searched.

getInstance

public static final TrustManagerFactory getInstance(String algorithm,
                                                    String provider)
                                             throws NoSuchAlgorithmException,
                                                    NoSuchProviderException

Generates a TrustManagerFactory object for the specified trust management algorithm from the specified provider.

Parameters:

algorithm - the standard name of the requested trust management algorithm.

provider - the name of the provider

Returns:

the new TrustManagerFactory object

Throws:

NoSuchAlgorithmException - if the specified algorithm is not available from the specified provider.

NoSuchProviderException - if the specified provider has not been configured.

getInstance

public static final TrustManagerFactory getInstance(String algorithm,
                                                    Provider provider)
                                             throws NoSuchAlgorithmException

Generates a TrustManagerFactory object for the specified trust management algorithm from the specified provider.

Parameters:

algorithm - the standard name of the requested trust management algorithm.

provider - an instance of the provider

Returns:

the new TrustManagerFactory object

Throws:

NoSuchAlgorithmException - if the specified algorithm is not available from the specified provider.

getProvider

public final Provider getProvider()

Returns the provider of this TrustManagerFactory object.

Returns:

the provider of this TrustManagerFactory object

init

public void init(KeyStore ks)
          throws KeyStoreException

Initializes this factory with a source of certificate authorities and related trust material. The provider may also include a provider-specific source of key material.

Parameters:

ks - the key store or null

getTrustManagers

public TrustManager[] getTrustManagers()

Returns one trust manager for each type of trust material.

Returns:

the trust managers
