Windows BitLocker is a data protection feature of Microsoft Windows that allows users to encrypt hard drives, removable drives, and other data storage media, and protect them from unauthorized access. It is available on Windows 10 Pro and Enterprise, as well as Windows Server 2019, 2016 and 2012. Windows BitLocker uses Advanced Encryption Standard (AES) with the cipher strength of 256-bit, which is an industry standard encryption method. It also has a Tamper-Resistant Platform (TPM) feature, which is a hardware component that stores encryption keys and helps protect against malicious attacks. Windows BitLocker also offers a "suspend protection" feature that allows users to temporarily disable encryption while still keeping the data encrypted. This feature can be used to troubleshoot hardware and software issues. Windows BitLocker also offers two-factor authentication, which requires users to provide a PIN or USB key before they can access their data. This helps guard against unauthorized access even if the device is stolen or lost.
