Class AlgorithmController

Maintains a dictionary with all available protocols.

Method Summary
	`__init__(self, positiveList, negativeList, defaultAlgorithm)` Initialises the Algorithm controller.
	`getAlgorithm(self, algName)` Provides the instance of the Algorithm with the requested name.
`List` of `String`	`getAvailableAlgorithms(self)` Returns a list of names of available algorithms.
`List` of `String`	`getOpenAlgorithms(self)` Returns a list of names of algorithms, which are currently initialised on this node.
	`loadKeys(self)` Loads the required keys for the algorithms.

Instance Variable Summary
`Dict` of {AlgorithmImplementationModules}	`_algorithms`: Dictionary of algorithms implemented and available on this node
`String`	`_defaultalgorithm`: Name of the algorithm to be used whenever none is defined
`Dict` of {AlgorithmImplementations}	`_openalgorithms`: Algorithms, which have been initialised; hence, keys are present and useable.

Method Details

init(self, positiveList=None, negativeList=None, defaultAlgorithm='rsa')
(Constructor)

Initialises the Algorithm controller.

The list of algorithms is loaded from the config file for algorithms.

If positiveList is given, only the algorithms defined in there will be used. If not positiveList is given, the negativeList will be checked. Algorithms given in there will be skipped when intialising the algorithms. If neither of the two lists is given, all algorithms defined in the config file for algorithms will be initialised and activated.

Parameters:: positiveList - List of names of algorithms to initialise
(type=List of String); negativeList - List of names of algorithms to skip for initialisation
(type=List of String); defaultAlgorithm - Name of algorithm to use if none is specified
(type=String)

getAlgorithm(self, algName)

Provides the instance of the Algorithm with the requested name.

getAvailableAlgorithms(self)

Returns a list of names of available algorithms.

Returns:: List of names of algorithms
(type=List of String)

getOpenAlgorithms(self)

Returns a list of names of algorithms, which are currently initialised on this node.

Returns:: List of names of algorithms
(type=List of String)

loadKeys(self)

Loads the required keys for the algorithms.

_defaultalgorithm

Name of the algorithm to be used whenever none is defined

Type:: String

_openalgorithms

Algorithms, which have been initialised; hence, keys are present and useable.
