In this video, we are going to take a look at bit locker and we will try to Understand how ‘bit locker’ works, what is bit locker? And why You should use ‘Bitlocker’? We will also try to understand how to Remove or unlock or crack bit locker encryption and how Forensics investigators i.e. Digital Forensics Investigators Decrypt Bitlocker encryption without the recovery key. So this video is a comprehensive summary of bit locker And it explains everything that you need to know about bitlocker From using bit locker to how bit locker works and how to crack Or unlock bit locker. Without wasting time, let’s start with the video. In this episode of ‘Simply Explained’ we are going to talk about bitlocker. So what is a bit locker?

Bitlocker uses an AES encryption algorithm with a 128-bit key And even a 256-bit key to encrypt disk volumes. Disk drives/partitions/ volumes and in-fact flash drives. drives. It protects the data when the hard drive is stolen and is Being used on another computer or when someone has Physical access to the drive to access the drive in an offline mode, Bitlocker requires a security key known as A recovery key. Bit-locker is generally aimed towards individual users Who may fall prey to computer/laptop theft. Theft. By the way, this video was sponsored by elcomsoft’s Disk decryptor software and elcomsoft basically makes Forensics investigation tools. While investigating You might have a drive which might be encrypted with bit locker. You might want to see the contents of the disk or the drive , There are methods which are explained in our previous video via which You can remove or disable bit locker encryption And even other encryptions like truevault and TrueCrypt. TrueCrypt. Elcomsoft basically provides and develops softwares For forensics investigators and allows them to Create and generate recovery keys for encryption with memory dump and various Other methods. A detailed video on How to use elcomsoft’s disk Decryptor for forensics investigation is available On this channel, So now let’s try to understand how to use Bitlocker, Before installing and using bit locker, let’s try to take a look at Bitlocker’s System Requirements. To Run bit locker you will need A Windows PC running on one of the OS flavours mentioned before, i.e. Windows Vista , Or above with Enterprise/Ultimate or Pro editions.
