Constructor Details

KeyManagerFactory

protected KeyManagerFactory(KeyManagerFactorySpi factorySpi,
Provider provider,
String algorithm)

Creates a new KeyManagerFactory.

Parameters:

factorySpi - the implementation delegate.

provider - the provider.

algorithm - the key management algorithm name.

Method Details

getDefaultAlgorithm

public static final String getDefaultAlgorithm()

Returns the default key manager factory algorithm name.

The default algorithm name is specified by the security property: 'ssl.KeyManagerFactory.algorithm'.

Returns:

the default algorithm name.

getInstance

public static final KeyManagerFactory getInstance(String algorithm)
                                           throws NoSuchAlgorithmException

Creates a new KeyManagerFactory instance for the specified key management algorithm.

Parameters:

algorithm - the name of the requested key management algorithm.

Returns:

a key manager factory for the requested algorithm.

Throws:

NoSuchAlgorithmException - if no installed provider can provide the requested algorithm.

NullPointerException - if algorithm is null (instead of NoSuchAlgorithmException as in 1.4 release)

getInstance

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

Creates a new KeyManagerFactory instance for the specified key management algorithm from the specified provider.

Parameters:

algorithm - the name of the requested key management algorithm name.

provider - the name of the provider that provides the requested algorithm.

Returns:

a key manager factory for the requested algorithm.

Throws:

NoSuchAlgorithmException - if the specified provider cannot provide the requested algorithm.

NoSuchProviderException - if the specified provider does not exist.

NullPointerException - if algorithm is null (instead of NoSuchAlgorithmException as in 1.4 release)

getInstance

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

Creates a new KeyManagerFactory instance for the specified key management algorithm from the specified provider.

Parameters:

algorithm - the name of the requested key management algorithm name.

provider - the provider that provides the requested algorithm.

Returns:

a key manager factory for the requested algorithm.

Throws:

NoSuchAlgorithmException - if the specified provider cannot provide the requested algorithm.

NullPointerException - if algorithm is null (instead of NoSuchAlgorithmException as in 1.4 release)

getAlgorithm

public final String getAlgorithm()

Returns the name of the key management algorithm.

Returns:

the name of the key management algorithm.

getProvider

public final Provider getProvider()

Returns the provider for this KeyManagerFactory instance.

Returns:

the provider for this KeyManagerFactory instance.

init

public final void init(KeyStore ks,
char[] password)
                throws KeyStoreException,
NoSuchAlgorithmException,
UnrecoverableKeyException

Initializes this instance with the specified key store and password.

Parameters:

ks - the key store or null to use the default key store.

password - the password for the specified key store or null if no key store is provided.

Throws:

KeyStoreException - if initializing this key manager factory fails.

NoSuchAlgorithmException - if a required algorithm is not available.

UnrecoverableKeyException - if a key cannot be recovered.

init

public final void init(ManagerFactoryParameters spec)
                throws InvalidAlgorithmParameterException

Initializes this instance with the specified factory parameters.

Parameters:

spec - the factory parameters.

Throws:

InvalidAlgorithmParameterException - if an error occurs.

getKeyManagers

public final KeyManager[] getKeyManagers()

Returns a list of key managers, one instance for each type of key in the key store.

Returns:

a list of key managers.
