Class QRUOVSigner

java.lang.Object
org.bouncycastle.pqc.crypto.qruov.QRUOVSigner
All Implemented Interfaces:
MessageSigner

public class QRUOVSigner extends Object implements MessageSigner
QR-UOV signature implementation. Signing outputs the bare signature, QRUOVParameters.getSignatureBytes() of them, and verification requires exactly that. The reference NIST KAT files record the signature || message "sm" envelope instead; that is a property of the KAT harness rather than of the signature, and the test rebuilds it.

    • init

      public void init(boolean forSigning, CipherParameters param)
      Description copied from interface: MessageSigner
      initialise the signer for signature generation or signature verification.
      Specified by:
      init in interface MessageSigner
      Parameters:
      forSigning - true if we are generating a signature, false otherwise.
      param - key parameters for signature generation.
    • generateSignature

      public byte[] generateSignature(byte[] message)
      Description copied from interface: MessageSigner
      sign the passed in message (usually the output of a hash function).
      Specified by:
      generateSignature in interface MessageSigner
      Parameters:
      message - the message to be signed.
      Returns:
      the signature of the message
    • 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
      Parameters:
      message - the message that was supposed to have been signed.
      signature - the signature of the message
