                         throws InvalidKeyException

Specified by:

engineInitVerify in class SignatureSpi

Throws:

InvalidKeyException

engineInitSign

protected void engineInitSign(PrivateKey privateKey,
                              SecureRandom random)
                       throws InvalidKeyException

Overrides:

engineInitSign in class SignatureSpi

Throws:

InvalidKeyException

engineInitSign

protected void engineInitSign(PrivateKey privateKey)
                       throws InvalidKeyException

Specified by:

engineInitSign in class SignatureSpi

Throws:

InvalidKeyException

engineUpdate

protected void engineUpdate(byte b)

Specified by:

engineUpdate in class SignatureSpi

engineUpdate

protected void engineUpdate(byte[] bytes,
                            int off,
                            int len)
                     throws SignatureException

Specified by:

engineSign in class SignatureSpi

Throws:

SignatureException

engineVerify

protected boolean engineVerify(byte[] sigBytes)
                        throws SignatureException

Specified by:

engineVerify in class SignatureSpi

Throws:

SignatureException

engineSetParameter

protected void engineSetParameter(String param,
                                  Object o)
                           throws InvalidParameterException

Not Supported

Specified by:

engineSetParameter in class SignatureSpi

Throws:

InvalidParameterException

engineSetParameter

protected void engineSetParameter(AlgorithmParameterSpec parameterSpec)
                           throws InvalidAlgorithmParameterException

Call this to change if randomized Signing is used or not or to change the context String. The MlDsaAlgorithmParameterSpec has to have the same security level as the parameters in the private key

Overrides:

engineSetParameter in class SignatureSpi

Parameters:

parameterSpec - the parameters

Throws:

InvalidAlgorithmParameterException - when the AlgorithmParameterSpec is not an instance of MlDsaAlgorithmParameterSpec, or when the method is called after initialization.

engineGetParameter

                             throws InvalidParameterException

Not Supported

Specified by:

engineGetParameter in class SignatureSpi

Throws:

InvalidParameterException

engineGetParameters

protected AlgorithmParameters engineGetParameters()

Overrides:

engineGetParameters in class SignatureSpi

Returns:

returns null
