    hi,

    Just been looking at DriveCrypt Plus Pack. From reading early posts here in Wilders. I got the impression that encyption software that encypts your whole OS, only gives "Local" protection, and does'nt protect you from online threats such as trojans,keyloggers being able to steal your information. But from reading some of the features that are highlighted on SecureStars website they mention the following : -

    · Trojan and keyboard sniffer protection preventing passwords from being sniffed / captured (red screen modus).

    · Anti dictionary and brute-force attack mechanisms (due to the nature of DCPP, it is the most difficult system to attack compared to anything else available.)

    So the question is, does it really add another layer of online protection ?

    Many thanks in advance for anyone with any input ?

    As far as I know, those features only apply to information entered into DCPP while "red screen mode" is enabled in the settings. You should see a red outline on the text boxes in DCPP when it is turned on.

    DCPP is a great utility in many aspects, but I can not think of a way it protects you from any online threats. It can however, keep people OUT of your computer as long as it is turned off, or locked (physically).

    It can also save you the trouble of using utilities for secure-delete, or encryption (since the whole HD is encrypted). The only place the information is ever unencrypted at is in your computer's memory, it is never actually decrypted on the hard drive. Programs running in your memory can still access the information though, because DCPP will decrypt it to them just as it would legit programs... it has no way to deny single processes.

    DCPP is a great util. to use with programs like AntiHook. Hope this cleared things up some.

    http://www.securstar.com/products_drivecryptpp.php:

    " How does it work ?
    As data is read from the hard disk, DCPP automatically decrypts the data before it is loaded into memory. When data is written back to the hard disk, it is automatically re-encrypted. This process is completely transparent to the user or any application programs, the data is caught "on the fly" as it transfers back and forth between the hard disk and memory. Consequently, users don't need to remember to decrypt or re-encrypt their data, or change the normal operation of their PC. In addition, only individual sectors are decrypted at any one time, not the whole hard disk. Other products that claim to be "on the fly" decrypt an entire file and load it into memory, creating significant security risks. DCPP is smarter and more secure because it decrypts only the specific sectors of a file that are in use. Unprotected data never resides on a DCPP encrypted disk."

    From DCPP help filed:

    "...DCPP combats this security flaw by providing a useful feature called 'Red Screen Mode'. When Red Screen Mode is enabled the fields that you type your Passwords into are outlined in red and any keys that you press are passed to DCPP in a safe and secure manner, Passwords that would have otherwise been intercepted by a keylogger are now securely passed directly to DCPP in a way that ensures keyloggers will not be able to get hold of them."

    Thanks AJohn for a great response. It does sound a great util, I suppose the only question now is then does all that dencryption/encryption cause any impact on computer performance. I find it hard to believe that if you were using Bittorent with multidownloads, that it could do it transprantly with no performance impact. Might leave it till this weekend to try the trial version, as i would think encrpting a whole HD/OS will take sometime to do. Many thanks once again for the great insight AJohn :) :) :)

    I use Torrents like you wouldn't believe, I suggest: www.utorrent.com

    I notice no slowdown in performance, but it uses around 1-3% pc usage max... you shouldn't have any problems unless you already run too much for your PC to handle.
