void	setFilename(String s) set file name to be processed. this file is the raw data to be read, or the input file processed by algorithm.
void	setPrivateKey(byte[] k) Set private key, if any, to algorithm
void	setPrivateKeyFromFile(String f) Set private key, if any, to algorithm from file
void	setPublicKey(byte[] k) Set public or symetric key to algorithm
void	setPublicKeyFromFile(String f) Set public or symetric key to algorithm from file
void	setup() setup will be implemented by each subclass
void	setupKeys() set up length and new arrays to public and private keys will be implemented by each algorithm
