BitLockerkryptering

BitLocker encryption is a built-in data protection feature developed by Microsoft for Windows operating systems, designed to provide full-disk encryption for data security. Introduced with Windows Vista and later integrated into Windows 7, 8, and 10, BitLocker helps safeguard sensitive information by encrypting entire volumes, including system drives, ensuring that data remains secure even if a device is lost or stolen.

The encryption process uses the Advanced Encryption Standard (AES) in either 128-bit or 256-bit modes, providing strong protection against unauthorized access. BitLocker supports multiple authentication methods, such as a Trusted Platform Module (TPM) chip, smart cards, or a password, to ensure that only authorized users can decrypt and access the data. For systems without a TPM, BitLocker To Go can encrypt external drives using a password.

To enable BitLocker, users must first ensure their system meets compatibility requirements, such as having a TPM 1.2 or higher, sufficient free disk space, and an activated Windows license. The encryption process can be initiated through the BitLocker Drive Encryption control panel or via Command Prompt for advanced users. Once activated, BitLocker runs in the background, automatically encrypting new data while preserving the performance of the system.

BitLocker also includes features like BitLocker recovery keys, which allow users to regain access to their data if authentication fails, and BitLocker To Go, which extends encryption capabilities to removable drives. While highly effective, BitLocker requires careful management of encryption keys and authentication methods to prevent lockouts or security vulnerabilities. Regular backups of recovery keys are recommended to mitigate risks associated with lost or forgotten credentials.
