Class NamedParameterSpec

java.lang.Object

java.security.spec.NamedParameterSpec

All Implemented Interfaces:: AlgorithmParameterSpec

Direct Known Subclasses:: ECGenParameterSpec

public class NamedParameterSpec extends Object implements AlgorithmParameterSpec

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.

Constructor Details

NamedParameterSpec

public NamedParameterSpec(String stdName)

Creates a parameter specification using a standard (or predefined) name stdName. For the list of supported names, please consult the documentation of the provider whose implementation will be used.

Parameters:

stdName - the standard name of the algorithm parameters. See the NamedParameterSpec section in the Java Security Standard Algorithm Names Specification for information about standard names.

Throws:

NullPointerException - if stdName is null.
