To use BitLocker at least two NTFS-formatted volumes are required: one for the operating system and another from which the operating system boots. It is a logical volume encryption system. CBC is not used over the whole disk it is applied to each individual sector. By default, it uses the AES encryption algorithm in cipher block chaining (CBC), since Windit also supports XEX-based tweaked-codebook mode with ciphertext stealing (XTS) with a 128-bit or 256-bit key. It is designed to protect data by providing encryption for entire volumes. In this post I will discuss BitLocker, what is it and what should you do? What is BitLocker?īitLocker is a full disk encryption feature included with Microsoft Windows. When you come across a system that is encrypted taking the right now makes your life a lot easier down the line. Without a decryption key, the data and the potential evidence can’t be accessed. Encryption is a challenge in forensics and the use of encryption to protect computer data is growing.
