CryptArkan encrypts and hides data files and directories
inside one or more container files, such as sound/music and
images. Hidden data can be directly read off an Audio CD.
Main features of CryptArkan include:
- Encrypts data files to be hidden
- Hides data files in multiple container files
- Whole directories can be hidden, preserving subdirectory structure
- Different hiding methods can be used for separate container files
- Different amounts of the original container file can be used for data (e.g. 1, 2, 4 or 8 bits of a 16 bit stereo WAV file)
- Data can be read directly from an Audio CD (created with container WAV files)
- Uses plugin technology: a new feature can be added by simply downloading a new plugin.
Currently the following plugins are available (check web site for updated list):
