Create an Encrypted Loopback Device

Post date: April 12, 2005, 18:04 Category: Security Views: 3331 Comments
Tutorial quote: A loopback device is a very special device that allows you to mount a normal file as it was a physical device. loopbacks can be encrypted: this becomes very useful sometimes.

Consider, as na example, that you need to encrypt a few files, nothing big, let's say 100 MB or so. Encrypting an entire partition could be too much. Then a cryptoloop could be the right solution to your problem.

dmcrypt

Post date: January 25, 2006, 22:01 Category: Security Views: 4286 Comments
Tutorial quote: Device-mapper is a new infrastructure in the Linux 2.6 kernel that provides a generic way to create virtual layers of block devices that can do different things on top of real block devices like striping, concatenation, mirroring, snapshotting, etc... The device-mapper is used by the LVM2 and EVMS 2.x tools. dm-crypt is such a device-mapper target that provides transparent encryption of block devices using the new Linux 2.6 cryptoapi. Writes to this device will be encrypted and reads decrypted. You can mount your filesystem on it as usual. But without the key you can't access your data. It does basically the same as cryptoloop only that it's a much cleaner code and better suits the need of a block device and has a more flexible configuration interface. The on-disk format is also compatible.

How to set up an encrypted filesystem in several easy steps

Post date: December 10, 2006, 08:12 Category: Security Views: 3325 Comments
Tutorial quote: There's been a lot of talk lately about encrypted partitions, and Debian is proud to offer a feature to easily create them in the etch installer since beta3. But what about existing systems? This guide walks you through setting up an encrypted partition using cryptsetup and LUKS.

TrueCrypt - Free opensource on the fly Disk Encryption tool

Post date: August 7, 2008, 22:08 Category: Security Views: 3327 Comments
Tutorial quote: TrueCrypt is a free opensource software system for establishing and maintaining an on-the-fly-encrypted volume (data storage device). On-the-fly encryption means that data are automatically encrypted or decrypted right before they are loaded or saved, without any user intervention. No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfile(s) or correct encryption keys. Entire file system is encrypted (e.g., file names, folder names, contents of every file, free space, meta data, etc).

Fbsplash on gentoo

Post date: April 12, 2005, 05:04 Category: Multimedia Views: 3540 Comments
Tutorial quote: Gensplash is a project started by Spock whose aim is to create a set of tools which could enrich the Gentoo boot process by displaying messages, animations, progress bars, etc. An explanation of the various things named *splash (bootsplash, gensplash, fbsplash, and splashutils) and how they relate to each other, can be found at Spock's Gensplash site.

Fbsplash is part of the gensplash project. According to fbsplash's documentation, "the framebuffer splash is a kernel feature that allows displaying a background picture on selected consoles and switching the first console to the so-called silent mode, while booting/rebooting/shutting down the system." The fbsplash device is accessed through the /dev/fbsplash device node. For fbsplash to work, a frame buffer device is required.

How to Create a Private Encrypted Folder On Ubuntu 8.10

Post date: March 5, 2009, 08:03 Category: System Views: 3900 Comments
Tutorial quote: eCryptfs is a POSIX-compliant enterprise-class stacked cryptographic filesystem for Linux.It provides advanced key management and policy features. eCryptfs stores cryptographic metadata in the header of each file written, so that encrypted files can be copied between hosts; the
file will be decryptable with the proper key, and there is no need to keep track of any additional information aside from what is already in the encrypted file itself. Think of
eCryptfs as a sort of “gnupgfs”.eCryptfs is a native Linux filesystem. The kernel module component of eCryptfs is part of the Linux kernel since 2.6.19.

A much easier way to install Ubuntu on a USB device (Stick or Hard Disk)!

Post date: June 1, 2008, 21:06 Category: Software Views: 4222 Comments
Tutorial quote: This tutorial will explain A much easier way to install Ubuntu on a USB device (Stick or Hard Disk).I was reading How to install Ubuntu Linux from USB Stick posted a while ago, and found it to be quite some work to get Ubuntu working on a USB stick. Besides, having to prepare your USB device, creating a separate partition on it which will be more or less “useless” after the installation, giving up 750MB of space?
