XMSSMTParameters

public XMSSMTParameters(int height,
                        int layers,
                        ASN1ObjectIdentifier digestOID,

Method Detail

getHeight

public int getHeight()

Getter height.

Returns:

XMSSMT height.

getLayers

public int getLayers()

Getter layers.

Returns:

XMSSMT layers.

getXMSSParameters
