+* \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.
