Sure! When processing a source file, SIZE automatically creates a file that can be considered a "key" in the cryptographic sense. This "key file" is always created only once and never repeated. Even if the same file is converted several times using SIZE technology, a new "key" file will be created each time. The conversion process itself is not determined by the "key", and the settings of the program are selected by the user at random.
