Interface	Preview Feature	Description
javax.crypto.KDFParametersPREVIEW	Key Derivation Function API	A specification of Key Derivation Function (KDFPREVIEW) parameters.
javax.crypto.spec.HKDFParameterSpecPREVIEW	Key Derivation Function API	Parameters for the combined Extract, Expand, or Extract-then-Expand operations of the HMAC-based Key Derivation Function (HKDF).

Class	Preview Feature	Description
javax.crypto.KDFPREVIEW	Key Derivation Function API	This class provides the functionality of a Key Derivation Function (KDF), which is a cryptographic algorithm for deriving additional keys from input keying material (IKM) and (optionally) other data.
javax.crypto.KDFSpiPREVIEW	Key Derivation Function API	This class defines the Service Provider Interface (SPI) for the Key Derivation Function (KDFPREVIEW) class.
javax.crypto.spec.HKDFParameterSpec.BuilderPREVIEW	Key Derivation Function API	This Builder builds Extract and ExtractThenExpand objects.
javax.crypto.spec.HKDFParameterSpec.ExpandPREVIEW	Key Derivation Function API	Defines the input parameters of an Expand operation as defined in RFC 5869.
javax.crypto.spec.HKDFParameterSpec.ExtractPREVIEW	Key Derivation Function API	Defines the input parameters of an Extract operation as defined in RFC 5869.
javax.crypto.spec.HKDFParameterSpec.ExtractThenExpandPREVIEW	Key Derivation Function API	Defines the input parameters of an ExtractThenExpand operation as defined in RFC 5869.
