Method Summary

Modifier and Type	Method	Description
OutputSigner<T>	createSigner(AsymmetricPrivateKey key, T parameters)	Create a signer which will create signatures against data written to its output stream.
OutputValidator<T>	createValidator(AsymmetricPublicKey key, T parameters, byte[] signature)	Create a validator which will verify against data written to its output stream against a signature.
OutputVerifier<T>	createVerifier(AsymmetricPublicKey key, T parameters)	Create a verifier which will verify signatures against data written to its output stream.

Method Details

createSigner

OutputSigner<T> createSigner(AsymmetricPrivateKey key,
 T parameters)

Create a signer which will create signatures against data written to its output stream.

Parameters:

key - the signing key to use.

parameters - the parameters to use to initialize the signer.

Returns:

an OutputSigner.

createVerifier

OutputVerifier<T> createVerifier(AsymmetricPublicKey key,
 T parameters)

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

Parameters:

key - the verification key to use.

parameters - the parameters to use to initialize the verifier.

Returns:

an OutputVerifier.

createValidator

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

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
