String	getAlgorithm() Returns the algorithm to be used in the signature
Date	getNotAfterSignerCertificate() Data of end of Certificate use.
PrivateKey	getPrivateKey() Returns the private key.
PrivateKey	getPrivateKeyForTimeStamp()
Provider	getProvider() Returns the provider.
PublicKey	getPublicKey() Returns the public key.
String	getSignatory()
void	setAlgorithm(SignerAlgorithmEnum algorithm) Set an algorithm pre-defined in enumeration.
void	setAlgorithm(String algorithm) Set a Signature Algorithm.
