Method Details

createSigner

public FipsOutputSignerUsingSecureRandom<FipsEC.DSAParameters> createSigner(AsymmetricPrivateKey key,
 FipsEC.DSAParameters parameters)

Return a generator of EC DSA signatures. Note this operator needs to be associated with a SecureRandom to be fully initialised.

Specified by:

createSigner in interface SignatureOperatorFactory<FipsEC.DSAParameters>

Specified by:

createSigner in class FipsSignatureOperatorFactory<FipsEC.DSAParameters>

Parameters:

key - the key to initialize the signature generator with.

parameters - parameters required to configure the generation.

Returns:

an OutputSignerUsingSecureRandom.

createVerifier

public FipsOutputVerifier<FipsEC.DSAParameters> createVerifier(AsymmetricPublicKey key,
 FipsEC.DSAParameters parameters)

Create a verifier for EC DSA signatures.

Specified by:

createVerifier in interface SignatureOperatorFactory<FipsEC.DSAParameters>

Specified by:

createVerifier in class FipsSignatureOperatorFactory<FipsEC.DSAParameters>

Parameters:

key - the key to initialize the verifier with.

parameters - parameters required to configure the verification.

Returns:

an OutputVerifier.

createValidator

public FipsOutputValidator<FipsEC.DSAParameters> createValidator(AsymmetricPublicKey key,
 FipsEC.DSAParameters parameters,
 byte[] signature)
                                                          throws InvalidSignatureException

Create a validator for EC DSA signatures.

Parameters:

key - the key to initialize the verifier with.

parameters - parameters required to configure the verification.

signature - the signature the data is to be validated against.

Returns:

an OutputVerifier.

Throws:

InvalidSignatureException
