Constructor Detail
TrustManagerFactory
- protected TrustManagerFactory(TrustManagerFactorySpi factorySpi,
- Provider provider,
- String algorithm)
factorySpi
- the delegate provider
- the provider algorithm
- the algorithm Method Detail
getDefaultAlgorithm
- public static final String getDefaultAlgorithm( )
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.
getAlgorithm
- public final String getAlgorithm( )
TrustManagerFactory
object.
This is the same name that was specified in one of the
getInstance
calls that created this
TrustManagerFactory
object.
TrustManagerFactory
object getInstance
- public static final TrustManagerFactory getInstance( String algorithm)
- throws NoSuchAlgorithmException
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.
algorithm
- the standard name of the requested trust management
algorithm. TrustManagerFactory
object NoSuchAlgorithmException
- if no Provider supports a
TrustManagerFactorySpi implementation for the
specified algorithm. getInstance
- public static final TrustManagerFactory getInstance( String algorithm,
- String provider)
- throws NoSuchAlgorithmException
- NoSuchProviderException
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.
algorithm
- the standard name of the requested trust management
algorithm. provider
- the name of the provider. TrustManagerFactory
object 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. getInstance
- public static final TrustManagerFactory getInstance( String algorithm,
- Provider provider)
- throws NoSuchAlgorithmException
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.
algorithm
- the standard name of the requested trust management
algorithm. provider
- an instance of the provider. TrustManagerFactory
object. NoSuchAlgorithmException
- if a TrustManagerFactorySpi
implementation for the specified algorithm is not available
from the specified Provider object. IllegalArgumentException
- if the provider is null. getProvider
- public final Provider getProvider( )
TrustManagerFactory
object.
TrustManagerFactory
object init
- public final void init(KeyStore ks)
- throws KeyStoreException
The provider typically uses a KeyStore as a basis for making trust decisions.
For more flexible initialization, please see
init(ManagerFactoryParameters)
.
init
- public final void init(ManagerFactoryParameters spec)
- throws InvalidAlgorithmParameterException
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.
spec
- an implementation of a provider-specific parameter
specification InvalidAlgorithmParameterException
- if an error is
encountered getTrustManagers
- public final TrustManager[] getTrustManagers( )
