Consider this scenario… Your computer running Linux somehow ran into a hardware glitch and had to be hauled to the neighborhood Computer service center. And you are asked to leave the machine at the service center and come back after a couple of days so that the technician can have a good look at it. But you are a bit worried because the harddisk contains the blue prints of the most secret project you are currently working on.

Ever been faced with such a situation where you have to contend with wringing your fingers in despair ? This is where the use of an encrypted file system gains prominence. If you had created an encrypted volume on your hard disk and were in the habit of saving all your sensitive data on to the encrypted volume, you could have had a sound sleep while your computer is being repaired at the service center.

In Linux there are a number of solutions to create encrypted volumes and encrypting and decrypting data on the fly. >>>>
