Class TrustManagerFactory

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()

  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 (set in the Java security properties file or by calling Security.setProperty(String, String)) to the desired algorithm name.

  Returns:

  the default algorithm name as specified in the Java security properties, 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

  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.

  Note that the list of registered providers may be retrieved via the Security.getProviders() method.

  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.

• getInstance

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

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

  A new KeyManagerFactory object encapsulating the KeyManagerFactorySpi implementation from the specified provider is returned. The specified provider must be registered in the security provider list.

  Note that the list of registered providers may be retrieved via the Security.getProviders() method.

  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.

  provider - the name of the provider.

  Returns:

  the new TrustManagerFactory object

  Throws:

  NoSuchAlgorithmException - if a TrustManagerFactorySpi implementation for the specified algorithm is not available from the specified provider.

  NoSuchProviderException - if the specified provider is not registered in the security provider list.

  IllegalArgumentException - if the provider name is null or empty.

  NullPointerException - if algorithm is null.

• getInstance

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

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

  A new TrustManagerFactory object encapsulating the TrustManagerFactorySpi implementation from the specified Provider object is returned. Note that the specified Provider object does not have to be registered in the provider list.

  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.

  provider - an instance of the provider.

  Returns:

  the new TrustManagerFactory object.

  Throws:

  NoSuchAlgorithmException - if a TrustManagerFactorySpi implementation for the specified algorithm is not available from the specified Provider object.

  IllegalArgumentException - if the provider is null.

  NullPointerException - if algorithm is null.

• getProvider

  public final Provider getProvider()

  Returns the provider of this TrustManagerFactory object.

  Returns:

  the provider of this TrustManagerFactory object

• 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.

  For more flexible initialization, please see init(ManagerFactoryParameters).

  Parameters:

  ks - the key store, or null

  Throws:

  KeyStoreException - if this operation fails

• init

  public final void init(ManagerFactoryParameters spec)
                  throws InvalidAlgorithmParameterException

  Initializes this factory with a source of provider-specific trust material.

  In some cases, initialization parameters other than a keystore may be needed by a provider. Users of that particular provider are expected to pass an implementation of the appropriate ManagerFactoryParameters as defined by the provider. The provider can then call the specified methods in the ManagerFactoryParameters implementation to obtain the needed information.

  Parameters:

  spec - an implementation of a provider-specific parameter specification

  Throws:

  InvalidAlgorithmParameterException - if an error is encountered

• 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.
