Initializes this exemption mechanism with a key and a set of algorithm parameters.
If this exemption mechanism requires any algorithm parameters
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.
