Class ConcatKDFParameters

java.lang.Object

se.swedenconnect.opensaml.xmlsec.encryption.support.ConcatKDFParameters

public class ConcatKDFParameters
extends Object

Class for representing parameter inputs to the ConcatKDF key derivation algorithm.

Note: The attribute values that are assigned using the setter methods or the ConcatKDFParameters(String, byte[], byte[], byte[]) constructor should not be padded according to the XML encryption standard (see ConcatKDFParams). Only the actual value should be assigned.

If you, for some reason, need to assign an attribute value whose bit length is not divisible by 8, you need to create a ConcatKDFParams object and assign it using ConcatKDFParameters(ConcatKDFParams).
