How to protect your data

Dekart Private Disk creates virtual encrypted disk and user may use it as usual hard disk in Windows. User defines file-image and password for this encrypted disk. "Virtual disk" means that all files and folders after encryption go to file-image. User should specify this file-image and access password when it is necessary to connect a disk and get access to Files and Folders. Every disk has its own letter (C:, D:) in Windows. Virtual disk also has its letter which you define on creation.

All of the programs that you are accustomed to working with will not be affected in any way when using standard and virtual disks. For them, this will be just another hard disk. The file-image of a virtual encrypted disk can have any name, extension, and access path (even a network path is good). The password is the only way to access virtual encrypted disk.

Encrypting confidential information is easy - simply transfer it from any media (other disks or the same computer, or floppies, Zip drives, etc.) to the Private disk and remember to store your new confidential data on this disk too, while storing non-sensitive information on any other disks. The Advanced Encryption Standard ( AES) in CBC mode with 128 bit key length is used as the virtual disk encryption algorithm. Is this encryption key reliable? Yes! According to the estimates of Bruce Schneier, Applied Cryptography , fitting the encryption key 128 bit long requires 4.2е10 22 processors performing 256 million encryption operations per second. But even in this case, the key will be cracked in a year.

Installing Dekart Private Disk is easy, and should not take longer than a minute. Dekart Private Disk is easy to operate. Just point it on file-image and enter password. Now you can work with your data in the usual fashion in virtual disk.
