Class SnovaSigner

java.lang.Object
  org.bouncycastle.pqc.crypto.snova.SnovaSigner

All Implemented Interfaces:

MessageSigner

public class SnovaSigner

extends java.lang.Object

implements MessageSigner

Implementation of the Snova digital signature scheme as specified in the Snova documentation. This class provides functionality for both signature generation and verification.

Snova 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.

public SnovaSigner()

Method Detail

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
