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.
