Initializes this exemption mechanism with a key and a set of algorithm parameters.
If this exemption mechanism requires any algorithm parameters and
params is null, the underlying exemption mechanism
implementation is supposed to generate the required parameters
itself (using provider-specific default values); in the case that
algorithm parameters must be specified by the caller, an
InvalidAlgorithmParameterException is raised.
