Understanding BitLocker and its Working Principle

BitLocker is a full-disk encryption feature built into Windows 10 that uses the Advanced Encryption Standard (AES) algorithm with a key length of 128 or 256 bits to encrypt the entire drive. This means that all data on your hard drive, including your operating system, applications, and personal files, is encrypted and inaccessible without the correct key.

When you enable BitLocker, Windows generates a unique encryption key, known as the BitLocker recovery key. This key is essential for decrypting your drive. There are several ways to manage your BitLocker recovery key:

Saving it to your Microsoft account: You can store the key online, accessible through your Microsoft account.
Saving it to a USB drive: You can create a physical copy of the recovery key on a USB flash drive.
Printing the recovery key: You can print a copy of the recovery key and keep it in a safe place.

BitLocker uses a combination of these methods to ensure that you can always access your data:

Pre-Boot Authentication: When your computer starts, BitLocker prompts you to enter your password or insert your USB drive with the recovery key.
TPM Chip: Trusted Platform Module (TPM) is a hardware component that stores encryption keys securely and protects against unauthorized access to the system.

Understanding the mechanism behind BitLocker is crucial when considering bypassing it. Remember that while bypassing BitLocker can seem like a quick solution, it can also lead to data loss or security vulnerabilities if not done correctly.
