KeyManagerFactory

public class KeyManagerFactory
extends Object

java.lang.Object
↳	javax.net.ssl.KeyManagerFactory

This class acts as a factory for key managers based on a source of key material. Each key manager manages a specific type of key material for use by secure sockets. The key material is based on a KeyStore and/or provider specific sources.

KeyManagerFactory

Added in API level 1

KeyManagerFactory (KeyManagerFactorySpi factorySpi, 
                Provider provider, 
                String algorithm)

Creates a KeyManagerFactory object.

Parameters
`factorySpi`	`KeyManagerFactorySpi`: the delegate
`provider`	`Provider`: the provider
`algorithm`	`String`: the algorithm

Public methods

getAlgorithm

Added in API level 1

String getAlgorithm ()

Returns the algorithm name of this KeyManagerFactory object.

This is the same name that was specified in one of the getInstance calls that created this KeyManagerFactory object.

Returns
`String`	the algorithm name of this `KeyManagerFactory` object.

getDefaultAlgorithm

Added in API level 1

String getDefaultAlgorithm ()

Obtains the default KeyManagerFactory algorithm name.

The default algorithm can be changed at runtime by setting the value of the "ssl.KeyManagerFactory.algorithm" security property (set in the Java security properties file or by calling setProperty(java.lang.String, java.lang.String)) to the desired algorithm name.

Returns
`String`	the default algorithm name as specified in the Java security properties, or an implementation-specific default if no such property exists.

See also:

setProperty(java.lang.String, java.lang.String)

getInstance

Added in API level 1

KeyManagerFactory getInstance (String algorithm)

Returns a KeyManagerFactory object that acts as a factory for key managers.

This method traverses the list of registered security Providers, starting with the most preferred Provider. A new KeyManagerFactory object encapsulating the KeyManagerFactorySpi 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`	`String`: the standard name of the requested algorithm. See the Java Secure Socket Extension Reference Guide for information about standard algorithm names.

Returns
`KeyManagerFactory`	the new `KeyManagerFactory` object.

Throws
`NoSuchAlgorithmException`	if no Provider supports a KeyManagerFactorySpi implementation for the specified algorithm.
`NullPointerException`	if `algorithm` is null.

Provider

getInstance

Added in API level 1

KeyManagerFactory getInstance (String algorithm, 
                String provider)

Returns a KeyManagerFactory object that acts as a factory for key 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`	`String`: the standard name of the requested algorithm. See the Java Secure Socket Extension Reference Guide for information about standard algorithm names.
`provider`	`String`: the name of the provider.

Returns
`KeyManagerFactory`	the new `KeyManagerFactory` object.

Throws
`NoSuchAlgorithmException`	if a KeyManagerFactorySpi 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

Added in API level 1

KeyManagerFactory getInstance (String algorithm, 
                Provider provider)

Returns a KeyManagerFactory object that acts as a factory for key managers.

A new KeyManagerFactory object encapsulating the KeyManagerFactorySpi 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`	`String`: the standard name of the requested algorithm. See the Java Secure Socket Extension Reference Guide for information about standard algorithm names.
`provider`	`Provider`: an instance of the provider.

Returns
`KeyManagerFactory`	the new `KeyManagerFactory` object.

Throws
`NoSuchAlgorithmException`	if a KeyManagerFactorySpi implementation for the specified algorithm is not available from the specified Provider object.
`IllegalArgumentException`	if provider is null.
`NullPointerException`	if `algorithm` is null.

getKeyManagers

Added in API level 1

KeyManager[] getKeyManagers ()

Returns one key manager for each type of key material.

Returns
`KeyManager[]`	the key managers

Throws
`IllegalStateException`	if the KeyManagerFactory is not initialized

getProvider

Added in API level 1

Provider getProvider ()

Returns the provider of this KeyManagerFactory object.

Returns
`Provider`	the provider of this `KeyManagerFactory` object

init

Added in API level 1

void init (ManagerFactoryParameters spec)

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

In some cases, initialization parameters other than a keystore and password 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`	`ManagerFactoryParameters`: an implementation of a provider-specific parameter specification

Throws
`InvalidAlgorithmParameterException`	if an error is encountered

init

Added in API level 1

void init (KeyStore ks, 
                char[] password)

Initializes this factory with a source of key material.

The provider typically uses a KeyStore for obtaining key material for use during secure socket negotiations. The KeyStore is generally password-protected.

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

Parameters
`ks`	`KeyStore`: the key store or null
`password`	`char`: the password for recovering keys in the KeyStore

Throws
`KeyStoreException`	if this operation fails
`NoSuchAlgorithmException`	if the specified algorithm is not available from the specified provider.
`UnrecoverableKeyException`	if the key cannot be recovered (e.g. the given password is wrong).
