Class TrustManagerFactory

java.lang.Object

javax.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.

Since:

Constructor Detail

TrustManagerFactory

public TrustManagerFactory()

Method Detail

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

getDefaultAlgorithm

public static final String getDefaultAlgorithm()

Obtains the default TrustManagerFactory algorithm name.

The default TrustManager can be changed at runtime by setting the value of the ssl.TrustManagerFactory.algorithm security property to the desired algorithm name.

Returns:

the default algorithm name as specified by the ssl.TrustManagerFactory.algorithm security property, or an implementation-specific default if no such property exists.

getInstance

public static final TrustManagerFactory getInstance(String algorithm)
                                             throws NoSuchAlgorithmException

Returns a TrustManagerFactory object that acts as a factory for trust managers.

This method traverses the list of registered security Providers, starting with the most preferred Provider. A new TrustManagerFactory object encapsulating the TrustManagerFactorySpi implementation from the first Provider that supports the specified algorithm is returned.

Parameters:

algorithm - the standard name of the requested trust management algorithm. See the Java Secure Socket Extension Reference Guide for information about standard algorithm names.

Returns:

the new TrustManagerFactory object.

Throws:

NoSuchAlgorithmException - if no Provider supports a TrustManagerFactorySpi implementation for the specified algorithm.

NullPointerException - if algorithm is null.

getTrustManagers

public final TrustManager[] getTrustManagers()

Returns one trust manager for each type of trust material.

Returns:

the trust managers

Throws:

IllegalStateException - if the factory is not initialized.

init

public final void init(KeyStore ks)
                throws KeyStoreException

Initializes this factory with a source of certificate authorities and related trust material.

The provider typically uses a KeyStore as a basis for making trust decisions.

Parameters:

ks - the key store, or null

Throws:

KeyStoreException - if this operation fails
