getL

public int getL()

getIndex

public long getIndex()

getLMSParameters

public LMSParameters[] getLMSParameters()

updateHierarchy

protected void updateHierarchy(LMSPrivateKeyParameters[] newKeys,

getUsagesRemaining

public long getUsagesRemaining()

extractKeyShard

public HSSPrivateKeyParameters extractKeyShard(int usageCount)

Return a key that can be used usageCount times.
