SnovaSigner (Bouncy Castle Library 1.85 API Specification)

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 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
