Package org.bouncycastle.pqc.crypto.mayo

Class MayoSigner

java.lang.Object
org.bouncycastle.pqc.crypto.mayo.MayoSigner
All Implemented Interfaces:
MessageSigner
public class MayoSigner extends Object implements MessageSigner
Implementation of the MAYO digital signature scheme as specified in the MAYO documentation. This class provides functionality for both signature generation and verification.

MAYO is a candidate in the NIST Post-Quantum Cryptography: Additional Digital Signature Schemes project, currently in Round 2 of evaluations. For more details about the NIST standardization process, see: NIST PQC Additional Digital Signatures.

    • generateSignature

      public byte[] generateSignature(byte[] message)
      Generates a MAYO signature for the given message using the initialized private key. Follows the signature generation process outlined in the MAYO specification document.
      Specified by:
      generateSignature in interface MessageSigner
      Parameters:
      message - The message to be signed
      Returns:
      The signature bytes concatenated with the original message

    • verifySignature

      public boolean verifySignature(byte[] message, byte[] signature)
      Verifies a MAYO signature against the initialized public key and message. Implements the verification process specified in the MAYO documentation.
      Specified by:
      verifySignature in interface MessageSigner
      Parameters:
      message - The original message
      signature - The signature to verify
      Returns:
      true if the signature is valid, false otherwise
