Protected Constructors

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

Added in API level 1

Creates a new KeyManagerFactory.

Parameters
factorySpi the implementation delegate.
provider the provider.
algorithm the key management algorithm name.

Public Methods

public final String getAlgorithm ()

Added in API level 1

Returns the name of the key management algorithm.

Returns
  • the name of the key management algorithm.

public static final String getDefaultAlgorithm ()

Added in API level 1

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.

public static final KeyManagerFactory getInstance (String algorithm, String provider)

Added in API level 1

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)

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

Added in API level 1

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)

public static final KeyManagerFactory getInstance (String algorithm)

Added in API level 1

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)

public final KeyManager[] getKeyManagers ()

Added in API level 1

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

Returns
  • a list of key managers.

public final Provider getProvider ()

Added in API level 1

Returns the provider for this KeyManagerFactory instance.

Returns
  • the provider for this KeyManagerFactory instance.

public final void init (ManagerFactoryParameters spec)

Added in API level 1

Initializes this instance with the specified factory parameters.

Parameters
spec the factory parameters.
Throws
InvalidAlgorithmParameterException if an error occurs.

public final void init (KeyStore ks, char[] password)

Added in API level 1

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.
