Encryption is a method of encoding information so that only authorized parties can access the encrypted data. Data is encrypted using an encryption algorithm, which uses a key to decrypt the information.

I can imagine if somebody would take snapshot of live RAM content and extract keys from registers even in hibernated mode. But as far as I know in order to get Windows to boot from encrypted partition - bitlocker volume I need to input bitlocker password first. Suppose somebody take my shut downed laptop protected by bitlocker and how he can pass initial password check in order to decrypt encrypted windows partition?

This step is not clear for me how to overide bitlocker on black-boxed system. There is this note in the article: IMPORTANT: Use Elcomsoft Forensic Disk Decryptor to acquire volumes encrypted with BitLocker Device Protection.

BitLocker Device Protection is a whole-disk encryption scheme that automatically protects certain Windows devices (such as tablets and ultrabooks equipped with TPM 2.0 modules) when the user logs in with their Microsoft Account. BitLocker Device Protection does NOT employ user-selectable passwords, and CANNOT be broken into by brute forcing anything. In certain cases, BitLocker escrow keys (BitLocker Recovery Keys) can be extracted by logging in to the user’s Microsoft Account via. The latest version of Elcomsoft Forensic Disk Decryptor (the one we’ve just released) has the ability to use these keys in order to decrypt or mount BitLocker volumes. This method only mainly works on computers encrypted using TPM rather than requiring a Bitlocker separate password. For the Bitlocker encryption where you have to type password to decrypt and continue the boot process, it is covered in their part 2: Essentially, they try as many password combinations as they can to break it.

If you have a strong password, that should deter this attack significantly (and length matters for the password). I am not quite as familiar with Bitlocker, but other people on this forums are. As far as I have read, a strong password should be sufficient for the second attack. -Chiragroop •. I am not certain but method described here is bruteforce attack assuming that bitlocker password is weak not strong?

How works there probing of brute force passwords? Is there some live USB utility with cracks bitlocker protected windows partition offline? For instance some script is inputting brute force password repeatedly until it crack real bit locker password and decrypt bitlocker protected partition by brute force method? Gents on other hands what is the strong, hack-proof password?

Suppose I am using 10 character password including capital letter, numbers and special character. Can we say that such password combination is proof against brute force method and even brute force attack is accelerated by GPU CUDA hardware it would take ages to break such password combination?

Bahkan saya juga saking gilanya sampai kemana2 menbaca kamus jerman-jerman.

Anyway my laptop is equipped just by older TPM 1.2. Is it enough to support bitlocker protection togheter with strong password described hereby?

Status of my TPM is TPM autorization is not stored properly and saying reset TPM. Does it mean problem with lowered TPM security?

I have found way how to enable passphrase instead of PIN here Now I reverted bitlocker off and doing TPM sync then re-enable bitlocker with stronger passphrase.

Allright thanks.I am maybe a bit paranoid so I am looking for higher level of security not just ordinar thief.I have sensitive business data which I signed nda there. Basically I was scared by article above describing how it is possible crack bitlocker a such. Gents nobody can advise about TPM issue above saying that tpm chip is just partly ready? Shall I reset tpm?

If so what precaution or care I shall take to avoid data loss on encrypted file system. I got idea to disable bitlocker a such and decrypt protected partition and then to do tpm sync and encypt partition again. Any advice would be highly welcomed.

After a discussion about encryption, a friend of mine challenged me to crack a file he encrypted using AES with a 128bit key. I know the file was originally a GIF image, so it should start with 'GIF8'. I'm wondering if it is possible to derive the password from this knowledge in a reasonable time (ie. A week or less). Stealing the key in any way other than analyzing the encrypted file is not possible, as it defeats the point of the challenge. If so, pointers would be welcome. I failed to find a decent flow-chart-like description of how the encryption of the first block works.
