Method Detail

getAlgorithmParameterSpec

protected java.security.spec.AlgorithmParameterSpec getAlgorithmParameterSpec(org.ssonet.mechanisms.MechanismConfiguration mechConf)

returns a algorithmParameterSpec for RC5

Overrides:

getAlgorithmParameterSpec in class AbstractConfidentialityMechanism

negotiateMechConf

protected org.ssonet.mechanisms.MechanismConfiguration negotiateMechConf(org.ssonet.mechanisms.MechanismConfiguration ownMechanismConfiguration,
                                                                         org.ssonet.mechanisms.MechanismConfiguration partnerMechanismConfiguration)

in addition to the negotiation Method of AbstractConfidentialityMechanism, this method negotiates the rounds used for this algorithm

Overrides:

negotiateMechConf in class AbstractConfidentialityMechanism

ParameterNotCompatibleException

getDefaultConfiguration

public org.ssonet.mechanisms.MechanismConfiguration getDefaultConfiguration()

Description copied from class: AbstractConfidentialityMechanism

Return the basic default configuration for a cipher algorithm. An algorithm, which needs another default configuration, must override this method. The Configuration consists of Cipher Modes (ECB, OFB, ....) and the Provider

Specified by:

getDefaultConfiguration in interface Mechanism

Overrides:

getDefaultConfiguration in class AbstractConfidentialityMechanism

Returns:

a default configuration setting for the mechanism.
