Kotlin |Java

open class KdfParameterSpec : NamedParameterSpec

kotlin.Any
↳	java.security.spec.NamedParameterSpec
	↳	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.

These parameters can be composed into a full HKPE suite name using Hpke.getSuiteName(KemParameterSpec,KdfParameterSpec,AeadParameterSpec).

Note that currently only HKDF_SHA256 is implemented.
