getPKCS11ParamsObject

public java.lang.Object getPKCS11ParamsObject()
Get this parameters object as an object of the CK_ECDH2_DERIVE_PARAMS class.
Overrides:
getPKCS11ParamsObject in class EcDH1KeyDerivationParameters
Returns:
This object as a CK_ECDH2_DERIVE_PARAMS object.

getPrivateData

public Object getPrivateData()
Get the key for the second EC private key value.
Returns:
