Direct Known Subclasses:

public class SignatureSpi
extends Signature

JCA SignatureSpi for UOV. Buffers the message bytes through engineUpdate then dispatches to the one-shot UOVSigner. Per-variant subclasses lock the SPI to a specific UOVParameters set; the generic SPI accepts whatever variant the supplied key carries.
