Method Detail

getInstance

public static CertifyingSigner getInstance(boolean forSigning,
                                           CertifiedKeyPair certifier,
                                           SignerFactory factory)

Get a certifying signer instance from the given signer factory for a given certifier.

Parameters:

forSigning - true for signing, and false for verifying.

certifier - the certified key pair of the certifier.

factory - a signer factory to create the signer.

Returns:

a certifying signer.
