public abstract class KeyManagerFactorySpi extends Object
KeyManagerFactory class.
All the abstract methods in this class must be implemented by each cryptographic service provider who wishes to supply the implementation of a particular key manager factory.

protected abstract KeyManager |
engineGetKeyManagers()
Returns one key manager for each type of key material.

protected abstract void |
engineInit(KeyStore
Initializes this factory with a source of key material.
|
protected abstract void |
engineInit(ManagerFactoryParameters
Initializes this factory with a source of key material.

protected abstract void engineInit(KeyStoreks, char[] password) throws KeyStoreException , NoSuchAlgorithmException , UnrecoverableKeyException
ks - the key store or null
password - the password for recovering keys
KeyStoreException - if this operation fails
NoSuchAlgorithmException - if the specified algorithm is not available from the specified provider.
UnrecoverableKeyException - if the key cannot be recovered
KeyManagerFactory.init(KeyStore, char[])
protected abstract void engineInit(ManagerFactoryParametersspec) throws InvalidAlgorithmParameterException
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.
spec - an implementation of a provider-specific parameter specification
InvalidAlgorithmParameterException - if there is problem with the parameters
KeyManagerFactory.init(ManagerFactoryParameters spec)
protected abstract KeyManager[] engineGetKeyManagers()
IllegalStateException - if the KeyManagerFactorySpi is not initialized
