NamedParameterSpec (Java SE 12 & JDK 12 )

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.
