A Windows program that creates encrypted volumes and files on your hard disk that can only be accessed via password. It supports numerous encryption algorithms and also allows data to be concealed in an existing WAV file (steganography). The dialog box below shows the various algorithms supported. See encryption algorithm for a brief explanation of each algorithm. The free version of ScramDisk is no longer being updated; however, an enhanced, commercial version called DriveCrypt is available from SecurStar GmbH (www.drivecrypt.com).
