Whole disk: Whether the whole physical disk or logical volume can be encrypted, including the partition tables and master boot record. 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.
Since disk encryption generally uses the same key for encrypting the whole drive, all of the data can be decrypted when the system runs. However, some disk encryption solutions use multiple keys for encrypting different volumes. If an attacker gains access to the computer at run-time, the attacker has access to all files.
The Linux Unified Key Setup (LUKS) is a disk encryption specification created by Clemens Fruhwirth in 2004 and originally intended for Linux.. LUKS implements a platform-independent standard on-disk format for use in various tools.
The geli utility is different from gbde in that it offers different features and uses a different scheme for doing cryptographic work. It supports the crypto framework within FreeBSD, allowing hardware cryptographic acceleration if available, as well as supporting more cryptographic algorithms (currently AES, Triple DES, Blowfish and Camellia) and data authentication/integrity verification via ...
The operating system uses an encrypted sparse disk image (a large single file) to present a volume for the home directory. Mac OS X 10.5 Leopard and Mac OS X 10.6 Snow Leopard use more modern sparse bundle disk images [2] which spread the data over 8 MB files (called bands) within a bundle. Apple refers to this original iteration of FileVault ...
Encryption for the Masses (E4M) is a free disk encryption software for Windows NT and Windows 9x families of operating systems. E4M is discontinued; it is no longer maintained. E4M is discontinued; it is no longer maintained.
Disk encryption generally refers to wholesale encryption that operates on an entire volume mostly transparently to the user, the system, and applications. This is generally distinguished from file-level encryption that operates by user invocation on a single file or group of files, and which requires the user to decide which specific files ...
In addition, implementing system wide hardware-based full disk encryption is prohibitive for many companies due to the high cost of replacing existing hardware. This makes migrating to hardware encryption technologies more difficult and would generally require a clear migration and central management solution for both hardware- and software ...
