java.lang.Object
org.bouncycastle.pqc.crypto.qruov.QRUOVSigner
All Implemented Interfaces:
MessageSigner
public class QRUOVSigner extends Object implements MessageSigner

    • verifySignature

      public boolean verifySignature(byte[] message, byte[] signature)
      Description copied from interface: MessageSigner
      verify the message message against the signature value.
      Specified by:
      verifySignature in interface MessageSigner
