CrossCrypt is an open-source on-the-fly encryption program for the Microsoft Windows XP/2000 operating systems.
CrossCrypt is based on FileDisk, virtual disk driver for Windows NT/2000/XP that uses one or more files to emulate physical disks, adding encrypted volumes functionality.
Application operates on .IMG file format disk images.
After burning it with any writing application disk looks blank when inserted into normal CD/DVD reading device (though, when mounted with the CrossCrypt application the state does not change, files are accessed in a new virtual drive).
The encryption algorithms supported by CrossCrypt include AES (256, 192, 128; SingleKey Mode aes-loop compatible) and TwoFish (160 Bit Key; SuSE Linux compatible).
