Before we dive into the compatibility of BitLocker with SSDs, it’s essential to understand what BitLocker is and how it works. BitLocker is a full-volume encryption feature that encrypts all data on a Windows operating system volume, including the operating system, user data, and swap files. This encryption tool uses the Advanced Encryption Standard (AES) with 128-bit or 256-bit keys to protect data from unauthorized access.
BitLocker was first introduced in Windows Vista and has since become a standard feature in Windows operating systems. It’s widely used by individuals and organizations to protect sensitive data from theft, loss, or unauthorized access.
How Does BitLocker Work?
To understand how BitLocker works on SSDs, it’s crucial to know the encryption process. Here’s a step-by-step explanation:
Encryption Process
- Initialization: When you enable BitLocker on a drive, it initializes the encryption process by creating a unique encryption key.
- Key Creation: BitLocker creates a volume master key, which is used to encrypt the data on the drive.
- Encryption: The volume master key is used to encrypt all data on the drive, including the operating system, user data, and swap files.
- Key Storage: The encryption key is stored in a secure location, such as the Trusted Platform Module (TPM) or a USB drive.
Decryption Process
- Boot Process: When you boot your computer, BitLocker checks for the presence of the TPM or USB drive containing the encryption key.
- Key Retrieval: If the TPM or USB drive is present, BitLocker retrieves the encryption key and uses it to decrypt the data on the drive.
- Decryption: The decrypted data is then loaded into memory, allowing you to access your files and applications.
