HI guys
Is there anyway to break a file which has been encrypted by Bitlocker in Windows 7 ?I've read somewhere it is possible but somewhere no.

    If its legal then I am sure you can find easy steps online :)

    Seriously though - it won't be easy, otherwise there wouldn't be a point in using Bitlocker in the first place - I doubt you get an answer here.

    The bitlocker key is AES-CBC-128, ie more or less uncrackable with current technology. I know of some commercial tools (which I'm not going to name here) that can recovery the master key from a system memory ****, but that's only going to work with powered on systems that have already been unlocked, and you have RDP/console access to.

    I intended no illegal activity.I was searching for some cryptographic algorithms that i found these :
    Schneier on Security: Microsoft's BitLocker
    Schneier on Security: Breaking Hard-Disk Encryption
    So i wanted to know f anybody has any experience with breaking this feature.By the way,thank you all for your information icon_thumright.gif

    The article is in line with what jmritenour said; the tool analyzes memory ****.

    You original question confuses me. Do you actually mean Bitlocker encryption? Bitlocker only encrypts drives, If you are talking about a single file maybe you mean EFS? What are the specifics of the scenario you present?

    I meant a drive,a 400G drive.The drive was deleted by mistake and it was encrypted by Bitlocker.Since the information was important I wanted to make sure if it is possible to recover the master key .However,I found the backup key which was made before and the problem was solved .If I couldn't find the key that was disastericon_rolleyes.gif

    If those machines are domain joined you may want to look into storing they key in AD. It just gives you that extra peace of mind.

    I am currently reviewing for the 70-680 and also have a question similar in nature to this except from the side of the TPM. Does BitLocker associate only a key or is it a key and some form of identifier. For example, if I had a Smart Card and someone stole it, couldn't they simply copy the data from the card and create their own TPM for my device?
