Method Details

createSigner

public FipsOutputSignerUsingSecureRandom<T> createSigner(AsymmetricPrivateKey key,
 T parameters)

Return an RSA based signer.

Note that while this method returns a FipsOutputSignerUsingSecureRandom, an attempt calls to withSecureRandom() for algorithms that do not require it will result in an error.

Specified by:

createSigner in interface SignatureOperatorFactory<T extends FipsRSA.SignatureParameters>

Specified by:

createSigner in class FipsSignatureOperatorFactory<T extends FipsRSA.SignatureParameters>

Parameters:

key - the signing key.

parameters - parameters for the algorithm required.

Returns:

an OutputSigner.

createVerifier

public FipsOutputVerifier<T> createVerifier(AsymmetricPublicKey key,
 T parameters)

Description copied from interface: SignatureOperatorFactory

Create a verifier which will verify signatures against data written to its output stream.

Specified by:

createVerifier in interface SignatureOperatorFactory<T extends FipsRSA.SignatureParameters>

Specified by:

createVerifier in class FipsSignatureOperatorFactory<T extends FipsRSA.SignatureParameters>

Parameters:

key - the verification key to use.

parameters - the parameters to use to initialize the verifier.

Returns:

an OutputVerifier.

createValidator

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

Description copied from interface: SignatureOperatorFactory

Create a validator which will verify against data written to its output stream against a signature.

Parameters:

key - the verification key to use.

parameters - the parameters to use to initialize the verifier.

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

Returns:

an OutputValidator.

Throws:

InvalidSignatureException
