On a Linux system, the boot partition (/boot) may be encrypted if the bootloader itself supports LUKS (e.g. GRUB). This is undertaken to prevent tampering with the Linux kernel. However, the first stage bootloader or an EFI system partition cannot be encrypted (see Full disk encryption#The boot key problem). [14]
In addition to the BSDs, a few Linux distributions have implemented similar infrastructure, including Gentoo's Portage, Arch's Arch Build System (ABS), CRUX's Ports and Void Linux's Templates. The main advantage of the ports system when compared with a binary distribution model is that the installation can be tuned and optimized according to ...
libdvdcss (or libdvdcss2 in some repositories) is a free and open-source software library for accessing and unscrambling DVDs encrypted with the Content Scramble System (CSS). libdvdcss is part of the VideoLAN project and is used by VLC media player and other DVD player software packages, such as Ogle, xine-based players, and MPlayer.
Pacman, a package manager written specifically for Arch Linux, is used to install, remove and update software packages. [13] An alternative is the Arch User Repository (AUR), which is the community-driven repository for Arch Linux; AUR packages can be downloaded and built, or installed through an AUR 'helper'.
The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices.It forms the foundation of the logical volume manager (LVM), software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots.
A wide-block disk encryption algorithm, Adiantum, was added in 5.0, and its AES-based cousin HCTR2 in 6.0. The Linux Crypto API includes support for most popular block ciphers and hash functions, which are all usable with dm-crypt. Crypted FS support include LUKS (versions 1 and 2) volumes, loop-AES, TrueCrypt/VeraCrypt (since Linux kernel 3.13 ...
pkg-config is software development tool that queries information about libraries from a local, file-based database for the purpose of building a codebase that depends on them. . It allows for sharing a codebase in a cross-platform way by using host-specific library information that is stored outside of yet referenced by the codeba
To protect the user’s information, blowfish encrypted data is authenticated with the SHA-1 hashing algorithm. KDE Wallet manager’s blowfish encryption provides faster encryption compared to Khufu, RC5, DES, IDEA, and Trip-DES. Blowfish encrypts at a rate of 18 clock cycles per byte in 32-bit microprocessors.
