Package org.bouncycastle.pqc.crypto.sdith

Class SDitHPrivateKeyParameters

java.lang.Object

org.bouncycastle.crypto.params.AsymmetricKeyParameter

org.bouncycastle.pqc.crypto.sdith.SDitHPrivateKeyParameters

All Implemented Interfaces:

CipherParameters

public class SDitHPrivateKeyParameters
extends AsymmetricKeyParameter

SDitH private key, in the same expanded form that the reference KAT files write out (sdith_full_key_t).

Layout:

   H_a_seed (seedSize)  ||  y (m-k)  ||  s_A (k)  ||  q_poly (d * w/d)  ||  p_poly (d * w/d)
 

The mSeed is held alongside the expanded key whenever it is known (after keygen); when reconstructed from a flat encoded blob we have only the expanded data and getSeed() returns null.
