When used in conjunction with a compatible Trusted Platform Module (TPM), BitLocker can validate the integrity of boot and system files before decrypting a protected volume; an unsuccessful validation will prohibit access to a protected system. [6] [7] BitLocker was briefly called Secure Startup before Windows Vista's release to manufacturing. [6]
Note that this does not imply that the encrypted disk can be used as the boot disk itself; refer to pre-boot authentication in the features comparison table. Partition: Whether individual disk partitions can be encrypted. File: Whether the encrypted container can be stored in a file (usually implemented as encrypted loop devices).
In the case of disk encryption applications that can be configured to allow the operating system to boot without a pre-boot PIN being entered or a hardware key being present (e.g. BitLocker in a simple configuration that uses a TPM without a two-factor authentication PIN or USB key), the time frame for the attack is not limiting at all.

Unlocking the bootloader allows installing and running unsigned code on a device, including user customized software. Operating outside the manufacturer specification might usually result in voiding any warranties and may make the device susceptible to data theft, as the integrity of the operating system (as intended by the manufacturer) can no longer be guaranteed. [1]
It can be used to verify that the system seeking the access is the expected system. [4] A limited number of disk encryption solutions have support for TPM. These implementations can wrap the decryption key using the TPM, thus tying the hard disk drive (HDD) to a particular device. If the HDD is removed from that particular device and placed in ...
One can plausibly claim that such a device or partition has been wiped to clear personal data. Portable or "traveller mode" means the encryption software can be run without installation to the system hard drive. In this mode, the software typically installs a temporary driver from the portable media. Since it is installing a driver (albeit ...
English is the most widely used language on the internet, and this is a further impetus to the use of Hinglish online by native Hindi speakers, especially among the youth. Google's Gboard mobile keyboard app gives an option of Hinglish as a typing language where one can type a Hindi sentence in the Roman script and suggestions will be Hindi ...
One way to classify this type of software is the type of cipher used. Ciphers can be divided into two categories: public key ciphers (also known as asymmetric ciphers), and symmetric key ciphers. [4] Encryption software can be based on either public key or symmetric key encryption. Another way to classify software encryption is to categorize ...
