Dekart Private Disk Light

Dekart Private Disk Light is free disk encryption software for Windows. This free disk encryption software creates a virtual encrypted disk within a file and mounts it as a real disk. All data encryption is extremely fast, automatic,  on-the-fly and with no performance penalty. Private Disk Light uses NIST certified AES 128-bit encryption to protect confidential information.

Private Disk Light creates one or more virtual encrypted disks on your hard drive and/or other external storage devices. Once a user creates a virtual encrypted disk, that disk is assigned a new drive letter and appears to the user like any other system drive (like the A: or C: drive). When the encrypted disk is mounted, the data is automatically encrypted and decrypted when the user writes or reads this data respectively.

The encrypted data can be accessed only after you enter the correct password. Without the password, the information from a secure disk is completely secure.

Important note: Dekart Private Disk contains No spyware, No adware, No viruses and it's freeware.

Private Disk Light is very easy to use and takes only a few minutes to install. Data encryption is an effortless process, requiring only the copying of files into the designated secure drive. Private Disk Light keeps information safe and secure, but currently its development has been stopped. The product offering better functionality than Dekart Private Disk Light, is Dekart Private Disk, a highly configurable advanced disk encryption software, offering a host of important features and options.


Why Dekart Private Disk is more secure than Dekart Private Disk Light?

In DPD Light your disk is encrypted by the "AES key" using AES algorithm; the "AES key" itself is encrypted by the "RC4 key" using RC4 algorithm with default key length installed on your computer. The length of RC4 key depends on Windows settings and can be either 56 or 128-bit. Open the "About" dialog in Internet Explorer and check if you have 128-bit encryption. The RC4 key is generated from your password using SHA-1 algorithm.

In Dekart Private Disk 2.xx we don't use Windows cryptography for data encryption. So the disk is encrypted using AES 256-bit algorithm. The AES key is encrypted using AES 256-bit algorithm. The second AES 256-bit key is also generated from your password using SHA-512.

So the difference is that we no longer use RC4 algorithm and switched completely to AES 256-bit encryption. Why two AES keys are necessary: one is used for Disk encryption (independent from your password) and another AES key is generated from your password. The answer is that this architecture allows to easily change the password without the need to reencrypt the whole disk's data. If you change the password – Disk's encryption key remains the same, it's just reencrypted with another AES key (generated from the new password).
