What's the process of bitlocker recovery key crack?

845    Asked by Ankesh Kumar in SQL Server , Asked on Dec 22, 2021

 Can I brute force bitlocker recovery key? Which software can I use for this? During my research of bitlocker recovery, I came across an article saying that it automatically decrypts hard drives on startup, without requiring the use of a PIN code, USB, or other form of authentication. This method does not require the user to do anything, and it is the least secure. Microsoft recommends using the TPM with a BitLocker PIN or startup key loaded on a USB to uplift security.

I tried finding the way for bitlocker recovery key crack and https://docs.microsoft.com/en-us/archive/blogs/si_team/bitlocker-recovery-password-details

says When a user is entering the key, we accept it 6 digits at a time, and then check to see if the number they just entered is exactly divisible by 11. If it is then we know it might form part of the key - if it doesn't then we know for sure it isn't a valid block. This guards against swapped digits, mis-entered numbers, etc, and we can safely report the entry error to the user. But does this check reduce the amount of work an attacker would have to do to brute force the underlying key? Consider that when we check a group of digits we aren't saying that they are the 'correct' group for that location in the key - merely that they could be a correct group, as they are divisible by 11.
