About BitLocker recovery
BitLocker is an encryption algorithm employed in Windows Vista and later version to provide solid protection of sensitive information against theft or unauthorized access by encrypting the entire disk sector by sector.
If you cannot access your BitLocker-encrypted drive, you need to begin BitLocker recovery right away. It is possible to get access to the encrypted disk with a passowrd or BitLocker recovery key.
But if you forget the BitLocker password and cannot find the BitLocker recovery key, this can be a problem for you to unlock BitLocker encrypted drive.
So here's what you need to know about BitLocker recovery. It is a process that allows you to access an inaccessible drive encrypted with BitLocker if unlocking the drive in the usual way does not work.
What do you need for a success BitLocker data recovery?
1. A valid password or BitLocker recovery key.
BitLocker is a disk-level encryption solution, so BitLocker recovery requires the password or 48-digit BitLocker recovery key to decrypt data from the drive encrypted by BitLocker.
2. BitLocker metadata is intact.
Now you might be wondering what is BitLocker metadata? So it is the container storing the encryption keys.
Generally speaking, the actual data on the encrypted volume is protected with either 128-bit or 256-bit AES algorithm. The key used to do the encryption, the Full Volume Encryption Key (FVEK) and/or TWEAK key, is stored in the BitLocker metadata on the protected volume. The FVEK key and/or TWEAK keys are encrypted using another key, namely the Volume Master Key (VMK). Several copies of the VMK are also stored in the metadata. Each copy of the VMK is encrypted using another key; also know as key-protector key.
So it is why BitLocker recovery requires the area on the disk which holds BitLocker metadata wasn't severely damaged or overwritten. Once the BitLocker metadata is corrupt, there is no way to decrypt data from BitLocker-encrypted drive.
