Scrambling a file is a good way to further increase an attack on the data. You can scramble either an encrypted file or even a binary regular file such as an executable file, although it is highly recommended to perform it after an encryption.
This feature is easy to use. All you have to do is define the PassPhrase, select the file you want to scramble and click Scramble. The resulting file is the same, so be very careful and use the correct PassPhrase otherwise you will have to redo the scramble with the wrong PassPhrase again. If you don't you will lose your data and the file will be unrecoverable.
Scrambling works the same way, so if you scramble a text file, the original text data is now scrambled. When you send it through again the original text is restored.
