This class is used to specify any algorithm parameters that are determined
by a standard name. This class also holds constants for standard parameter
set names. The names of these constants exactly match the corresponding
parameter set name. For example, NamedParameterSpec.X25519 represents the
parameter set identified by the string "X25519". These strings are defined
in the 
         Java Security Standard Algorithm Names Specification.
