NamedParameterSpec
open class NamedParameterSpec : AlgorithmParameterSpec
Known Direct Subclasses
| ECGenParameterSpec |
This immutable class specifies the set of parameters used for generating elliptic curve (EC) domain parameters.
|
|
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.
Summary
