Constructor Detail

LocalKeyManagerAPI

public LocalKeyManagerAPI()
                   throws KeyManagerAPIInstantiationException

Throws:

KeyManagerAPIInstantiationException

Method Detail

setConfiguration

public void setConfiguration(KeyManagerAPIConfiguration configuration)
                      throws IllegalArgumentException,
                             KeyManagerAPIInstantiationException

Description copied from interface: KeyManagerAPI

Set the configuration for this KeyManagerAPI instance.

Before a KeyManagerAPI instance can actually be used, it first needs to be configured. The configuration passed to this method will be marked read-only.

Specified by:

setConfiguration in interface KeyManagerAPI

Overrides:

setConfiguration in class AbstractKeyManagerAPI

Parameters:

configuration - the configuration (which will be marked read-only by this operation). Must not be null.

Throws:

IllegalArgumentException - if the configuration is null or incomplete (e.g. configuration.keyStoreID being null).

KeyManagerAPIInstantiationException - if the actual implementation cannot be instantiated.

initDateDependentKeyStrategy

public DateDependentKeyStrategyInitResult initDateDependentKeyStrategy(DateDependentKeyStrategyInitParam param)
                                                                throws KeyStoreNotEmptyException,
                                                                       IOException

Description copied from interface: KeyManagerAPI

Initialise a new key-store with the DateDependentKeyStrategy.

Parameters:

param - the settings controlling the details of how to initialise it. Must not be null.

Returns:

Throws:

KeyStoreNotEmptyException

IOException

putUser

public void putUser(String userName,
                    char[] password)
             throws AuthenticationException,
                    IOException

Description copied from interface: KeyManagerAPI

Create a new user or change an existing user's password. If the password of the current user is modified, this instance of KeyManagerAPI will be updated with a new configuration, automatically. Other instances of KeyManagerAPI - even in the same JVM - are not updated, though.

Parameters:

userName - the name of the new user.

password - the password of the new user.

Throws:

AuthenticationException - if the authUserName or the authPassword is incorrect.

IOException - if the communication with the key-store (either local key-store-file or remote key-server) fails.

deleteUser

public void deleteUser(String userName)
                throws AuthenticationException,
                       CannotDeleteLastUserException,
                       IOException

Description copied from interface: KeyManagerAPI

Delete a user. If the specified user does not exist, this method is a no-op. Note, that the current user can delete himself. In this case, a 2nd call to this method would cause an AuthenticationException.

Parameters:

userName - the name of the user to be deleted.

Throws:

AuthenticationException - if the authUserName or the authPassword is incorrect.

CannotDeleteLastUserException - if you attempted to delete the last user (which would render the key-store to be totally unreadable).

IOException - if the communication with the key-store (either local key-store-file or remote key-server) fails.

getCryptoSession

public CryptoSession getCryptoSession(String appServerBaseURL)
                               throws IOException,
                                      AuthenticationException

Description copied from interface: KeyManagerAPI

Get a session for a certain application server.

Parameters:

appServerBaseURL - the base-url of the app-server-key-manager-channel (must not be null). This is the part of the URL before the "/KeyManagerChannel" - e.g. if the REST URL of the KeyManagerChannel-service is "https://serverUsingCumulus4j.mydomain.org/org.cumulus4j.keymanager.back.webapp/KeyManagerChannel", then this must be "https://serverUsingCumulus4j.mydomain.org/org.cumulus4j.keymanager.back.webapp".

Returns:

the session; never null.

Throws:

IOException - if the communication with the key-store (either local key-store-file or remote key-server) fails.

AuthenticationException - if the authUserName or the authPassword is incorrect.
