Why Dekart Private Disk is more secure than Dekart Private Disk Light?
DPD Light: a) Your disk is encrypted by the “AES key” using AES algorithm. b) Your “AES key” is encrypted by the “RC4 key” using RC4 algorithm with default key length installed on your computer. Length of RC4 key could be 56 or 128 bit it depends on Windows. Open about dialog in IE and check if you have 128 bit encryption. c) RC4 key is generated from your password using SHA-1 algorithm. In Dekart Private Disk 2.xx we don’t depend on (use) Windows cryptography at all. So the disk is encrypted with the AES 256-bit algorithm. The AES key is encrypted using the AES 256-bit algorithm as well. The second AES 256-bit key is also generated from your password using SHA-512.The main difference is that we no longer use the RC4 algorithm, and switched completely to AES 256-bit. Why two AES keys: one for Disk encryption (independent from your password) and another AES key – that is generated from your password.This architecture allows to change the password without the need to reencrypt the whole
