* \class CryptClassNullCipher
* \brief For testing purposes, NullCipher does nothing to the Text.
*
* The NullCipher class is, like all Ciphers/Algorithm-classes, derived from CryptclassBase.
* It's intended to be used for testing purposes of the overall Programm-Funcionality only and does
* no encryption whatsoever. Data is merely copied from m_cryptText to m_clearText and vice versa.
