```
protected void engineUpdate(byte b)
                     throws SignatureException
```
    Description copied from class: SignatureSpi
    
    Updates the data to be verified or to be signed, using the specified byte.
    
    Specified by:
    
    engineUpdate in class SignatureSpi
    
    Parameters:
    
    b - the byte to update with.
    
    Throws:
    
    SignatureException - if this SignatureSpi instance is not initialized properly.
  - engineUpdate

                     throws SignatureException
```
    Description copied from class: SignatureSpi
    
    Generates and returns the signature of all updated data.
    This SignatureSpi instance is reset to the state of its last initialization for signing and thus can be used for another signature from the same identity.
    
    Specified by:
    
    engineSign in class SignatureSpi
    
    Returns:
    
    the signature of all updated data.

    SignatureException - if this SignatureSpi instance is not initialized properly.
  - engineVerify
```
protected boolean engineVerify(byte[] sigBytes)
                        throws SignatureException
```
    Description copied from class: SignatureSpi
    
    Indicates whether the given sigBytes can be verified using the public key or a certificate of the signer.
    This SignatureSpi instance is reset to the state of its last initialization for verifying and thus can be used to verify another signature of the same signer.
    
    Specified by:
    
    engineVerify in class SignatureSpi
    
    Parameters:
    
    sigBytes - the signature to verify.
    
    Returns:
