# NamedParameterSpec

` public class NamedParameterSpec `   
` extends https://developer.android.com/reference/java/lang/Object ` ` implements https://developer.android.com/reference/java/security/spec/AlgorithmParameterSpec `

Known direct subclasses [AeadParameterSpec](https://developer.android.com/reference/android/crypto/hpke/AeadParameterSpec), [ECGenParameterSpec](https://developer.android.com/reference/java/security/spec/ECGenParameterSpec), [KdfParameterSpec](https://developer.android.com/reference/android/crypto/hpke/KdfParameterSpec), [KemParameterSpec](https://developer.android.com/reference/android/crypto/hpke/KemParameterSpec) [AeadParameterSpec](https://developer.android.com/reference/android/crypto/hpke/AeadParameterSpec) Specifies algorithm parameters for the AEAD component of an HPKE suite which are determined by standard names as per RFC 9180. [ECGenParameterSpec](https://developer.android.com/reference/java/security/spec/ECGenParameterSpec) This immutable class specifies the set of parameters used for generating elliptic curve (EC) domain parameters. [KdfParameterSpec](https://developer.android.com/reference/android/crypto/hpke/KdfParameterSpec) Specifies algorithm parameters for the KDF component of an HPKE suite which are determined by standard names as per RFC 9180. [KemParameterSpec](https://developer.android.com/reference/android/crypto/hpke/KemParameterSpec) Specifies algorithm parameters for the KEM component of an HPKE suite which are determined by standard names as per RFC 9180.   

*** ** * ** ***

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](https://docs.oracle.com/en/java/javase/17/docs/specs/security/standard-names.html#namedparameterspec).
