Constructor Detail

KeyManagerFactory

protected KeyManagerFactory(KeyManagerFactorySpi kmfSpi,
                 java.security.Provider provider,
                 java.lang.String algorithm)

Create a new key manager factory.

Parameters:

kmfSpi - The underlying engine.

provider - The engine's provider.

algorithm - The name of this algorithm.

Method Detail

getDefaultAlgorithm

public static final java.lang.String getDefaultAlgorithm()

Get the default algorithm name. This value may be specified at run-time via the security property "ssl.KeyManagerFactory.algorithm". If this property is not specified, this method returns "JessieX509".

Returns:

The default key manager factory algorithm's name.

getInstance

public static final KeyManagerFactory getInstance(java.lang.String algorithm)
                                           throws java.security.NoSuchAlgorithmException

Create an instance of the named key manager factory, from the first provider that implements it.

Parameters:

algorithm - The type of key manager factory to get.

Returns:

An appropriate implementation of that algoritm.

Throws:

java.security.NoSuchAlgorithmException - If no provider implements the requested algorithm.

java.lang.IllegalArgumentException - if algorithm is null or is an empty string.

getInstance

public static final KeyManagerFactory getInstance(java.lang.String algorithm,
                            java.lang.String provider)
                                           throws java.security.NoSuchAlgorithmException,
                                                  java.security.NoSuchProviderException

Create an instance of the named key manager factory, from the named provider.

Parameters:

algorithm - The type of key manager factory to get.

provider - The name of the provider to get the implementation from.

Returns:

An appropriate implementation of that algorithm.

Throws:

java.security.NoSuchAlgorithmException - If the provider does not implement the requested algorithm.

java.security.NoSuchProviderException - If the named provider does not exist.

java.lang.IllegalArgumentException - if either algorithm or provider is null, or if algorithm is an empty string.

getInstance

public static final KeyManagerFactory getInstance(java.lang.String algorithm,
                            java.security.Provider provider)
                                           throws java.security.NoSuchAlgorithmException

Create an instance of the named key manager factory, from the given provider.

Parameters:

algorithm - The type of key manager factory to get.

provider - The provider to get the implementation from.

Returns:

An appropriate implementation of that algorithm.

Throws:

java.security.NoSuchAlgorithmException - If the provider does not implement the requested algorithm.

java.lang.IllegalArgumentException - if either algorithm or provider is null, or if algorithm is an empty string.

getAlgorithm

public final java.lang.String getAlgorithm()

Returns the name of this key manager factory algorithm.

Returns:

The name of this key manager factory algorithm.

getKeyManagers

public final KeyManager[] getKeyManagers()

Get an array of key managers appropriate for this algorithm, with the most preferred manager first.

Returns:

The array of key managers.

getProvider

public final java.security.Provider getProvider()

Returns the provider of this implementation.

Returns:

The provider of this implementation.

init

public final void init(ManagerFactoryParameters params)
                throws java.security.InvalidAlgorithmParameterException

Initialize this instance with an implementation-dependent parameter object.

Parameters:

params - The parameters to initialize with.

Throws:

java.security.InvalidAlgorithmParameterException - If the specified parameters are inappropriate.

init

public final void init(java.security.KeyStore store,
        char[] passwd)
                throws java.security.KeyStoreException,
                       java.security.NoSuchAlgorithmException,
                       java.security.UnrecoverableKeyException

Initialize this instance with a key store and a password for private key entries.

Parameters:

store - The key store to read.

passwd - The password protecting private keys in the store.

Throws:

java.security.KeyStoreException - If an error occurs reading the keys.

java.security.NoSuchAlgorithmException - If an algorithm (such as a certificate algorithm) is not available.

java.security.UnrecoverableKeyException - If the password is incorrect.
