In cryptography, the EFF DES cracker (nicknamed "Deep Crack") is a machine built by the Electronic Frontier Foundation (EFF) in 1998, to perform a brute force search of the Data Encryption Standard (DES) cipher's key space – that is, to decrypt an encrypted message by trying every possible key.
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]
The Data Encryption Standard (DES / ˌ d iː ˌ iː ˈ ɛ s, d ɛ z /) is a symmetric-key algorithm for the encryption of digital data. Although its short key length of 56 bits makes it too insecure for modern applications, it has been highly influential in the advancement of cryptography.
This table lists the eight S-boxes used in DES. Each S-box replaces a 6-bit input with a 4-bit output. Given a 6-bit input, the 4-bit output is found by selecting the row using the outer two bits, and the column using the inner four bits.
In their review of Linux Mint 18, ZDNet said "You can turn the Linux Mint Cinnamon desktop into the desktop of your dreams." [35] In their review of Linux Mint 22, It's FOSS praised Cinnamon 6.0 by stating "Linux Mint complements its name as a refreshing offering in the world of Linux distributions. It does not fail to provide useful features ...
The contest demonstrated how quickly a rich corporation or government agency, having built a similar machine, could decrypt ciphertext encrypted with DES. The text was revealed to be "The secret message is: It's time for those 128-, 192-, and 256-bit keys." [3] DES Challenge III was a joint effort between distributed.net and Deep Crack. The key ...
Several Linux distributions were affected, including Debian [132] (and derivatives such as Linux Mint and Ubuntu [133]) and Red Hat Enterprise Linux [134] (and derivatives such as CentOS, [135] Oracle Linux 6 [129] and Amazon Linux [136]), as well as the following operating systems and firmware implementations:
