Ubuntu :: Decrypting A 256-bit AES-encrypted File?

May 2, 2011

So I have a jpg image file that was encrypted using 256-bit AES, and I know the passphrase. That is ALL the information I have about the file. Is there a way (under Ubuntu, preferably but not necessarily on the command line) to decrypt this file?

Ubuntu Security :: Decrypting Document Encrypted On Smartphone?

Feb 26, 2010

I'm an absolute beginner at encryption. gpg and keys still have me somewhat mystified, so please forgive me if the following seems like a stupid question. I'm looking at encryption software for my smartphone. I've found a Java program called TinyEncryptor that uses the TwoFish algorithm and claims to be a shell for the "Legion of the Bouncy Castle" libraries. It just uses a passphrase; there are no keys involved as far as I am aware.

Naturally, I would like to be able to decrypt files on my desktop that I've encrypted with this program. So far, I've not had any success with finding one.

OpenSUSE Install :: Migrating The Encrypted Home-directory?

Oct 5, 2010

I am trying to open an encrypted home directory from opensuse 11.2 with opensuse 11.3. This means i have a user.img and a user.key So far i have done:

losetup /dev/loop3 user.img
cryptsetup luksOpen /dev/loop3 home
Enter passphrase for /dev/loop3:

No key available with this passphrase. At this point it will not accept my passphrase.

A luksDump reveals:

cryptsetup luksDump /dev/loop3
LUKS header information for /dev/loop3

[code]....

When i try to use the key file, i get:

cryptsetup luksOpen /dev/loop3 home --key-file home.key No key available with this passphrase.

Fedora :: Decrypting And Merging PDFs?

Jan 24, 2010

I recently popped in the CD that came with one of my textbooks from school and figured I would be able to rip it pretty easily, but guess what? Too my surprise I find that each chapter of the textbook has it's own PDF file and that each one is encrypted. Is there anyway I can decrypt the PDFs and merge them all into one?

Fedora Security :: Remotely Decrypting Or Removing Encryption?

Jun 14, 2011

I have a computer running Fedora 14 and when I installed it, I chose to encrypt the drive.

I've recently changed the way I have things set up and don't want the encryption any more. From what I've read there is no way to simply and easily remove the encryption, so what I would like to do is input the pass phrase remotely.

so, Is there anyway I can type in the pass phrase remotely, or remove the encryption?

Fedora Installation :: Migrating Away From Gnome

Apr 13, 2011

I've been looking at Gnome 3 and the Gnome Shell and I don't like what I see. The Gnome devs are taking things in a direction I don't like, giving us new ways to do things that don't interest me and making them mandatory. AFAICT, in the long run there's no real way to configure things to work the way I've been doing things for the last fifteen years. This is not a rant, not (mostly) a complaint, merely an observation. Clearly, I'm not part of their target demographic and I doubt that I'd want to be under the circumstances.

To me, that means it's time for me to move on and try something different. After some careful research, I've migrated my laptop to XFCE and am very happy with it. Now, I'm about to do the same to my desktop. This leaves me with an interesting question: what's the best way to remove Gnome from my two machines without removing any support needed for various programs that I'm accustomed to using and expect to continue using?

CentOS 5 :: Migrating Lamp On Red Hat (or Fedora)?

We've got to move a LAMP web application from a Red Hat box over to Cent OS. Actually it might wind up being a few applications. Basically are there any scary monsters to watch out for?

I will have some more details tomorrow morning as to exactly what we're moving and off of and on to what. The Cent OS installation I believe is 5ish. Red Hat could be a wildcard. <-It might be Red Hat, Red Hat Enterprise or Fedora

Ubuntu Security :: 10.04 Installed - Home Directory Not Decrypting

May 5, 2010

I have a major major issue with an encrypted /home directory. I had used encryption on my home directory when I installed 9.10. However, I had not noticed that I needed to store the automatically generated passphrase anywhere. Now, upon installing 10.04, my home directory would not decrypt. I checked my .encryptfs directory and the wrapped-passphrase file is GONE. I only have the Private.sig files from my 9.10 installation and of course know the login password I binded to the passphrase. I can see my .Private directory with filenames starting with ECRYPTFS_FNEC_ENCRYPTED. Now, my PhD thesis which I have to deliver in 2 weeks is in there. With no backups. How to recover my data. If no 'normal' method would work, is it possible to use a brute force attack and feed it my login password?

Ubuntu :: Home Directory Not Decrypting On Login - 10.04 Ecryptfs?

Oct 11, 2010

Ubuntu 10.04 LTS Ran some updates,finally got around to rebooting. When I rebooted, It came up with Some errors about missing files. Came to discover my home directory was not decrypted. I simply had a readme file that said to run "encryptfs-mount-private". When I do it doesn't tell me the passphrase is incorrect, it tells me

Code:

Inserted auth tok with sig [xxxxxxxxxx] into the user session keyring You do not own that encrypted directory and I do own it. If I put in a different pass it tells me it's incorrect, I'm logging in fine, but my home directory is remaining encrypted.

Security :: Remotely Decrypting A Server - Authenticate A Decryption Mechanism Of Some Sort?

Sep 11, 2010

i need to find a way to securely authenticate a decryption mechanism of some sort where the authentication is provided remotely without any user-interaction. Right now i have a number of boxes that all inform a central server when they are online. When they do this an OpenVPN connection is set up between them and the server.

However, i have been given the task to ensure that the scripts involved in this process are encrypted by default. This requires some form of self-decryption, which to my mind kind of goes against the whole idea of encryption/authentication in the first place. I need some way to leave decrypted the bare essentials required to boot a box and securely connect to the central server automatically. Then the server would automatically send a key/passphrase and the rest of the files on the box would then be decrypted on the fly.

I figured out how to get the icon on the top panel, but that is naturally started as my user gsm.

Is there an easy way of migrating the whole mailbox and subfolders form the root install to the gsm user?

Or is it easier to start from scratch?

Ubuntu Security :: Main Encrypted LVM Not Accessible After Deleting A Different Encrypted LVM On USB HD

Mar 7, 2011

I installed Ubuntu 10.10 64 on my laptop with the entire 500gb setup as encrypted LVM. This has worked well for several months with no problems. During this time i have been backing up the data to an external usb drive (1tb) on a regular basis. The usb drive was not encrypted. So, I thought it would be a good idea to encrypt the backup drive too. I wiped out the backup drive and set it up as one large encrypted lvm and mbr. This seemed to work fine but immediately afterwards I decided to erase that and set it up as encrypted lvm guid instead of mbr. I couldn't delete it while logged into my desktop so i decided to do it from a bootable gparted usb stick. In gparted i erased the 1TB backup drive once again and planned on setting it up the way I wanted once I was logged back into my ubuntu desktop. Now I cant boot into my desktop with the following errors:

cryptsetup: evms_activate is not available b0d) does not begin with /dev/mapper/

Then after waiting for a few minutes I get an error followed by (initramfs)

When booting from a live version of ubuntu the 250MB boot patition is recognized and 500 partion is there but it is labeled as empty/unused.

Also, I did choose to use the exact same passphrase as what is used on the main bootable drive when I set up the encrypted partition on the external 1TB drive.

General :: Preserve "My Documents" While Migrating From XP To Fedora?

Jul 16, 2010

Install Linux (Fedora) on a laptop, that has XP right now (removing XP completely). Preserve the contents of "My Documents" on the same hdd while installing linux on my laptop (external hdd unavailable) The installed Linux to use full hdd space, contents of "My Documents" to be in /home, and have no leftover partition, that was used while migrating. It would be nice to have a regular hdd scheme after all of that.

Fedora :: Selinux On Encrypted Root?

Oct 2, 2009

After my cloning problems this morning were resolved, I have been able to complete conversion of the clone to run from an encrypted root partition. However, I have been unable to enable selinux when running from the encrypted root. /etc/selinux/config contains the settings that work on my unencrypted system

SELINUX=enforcing
SELINUXTYPE=targeted

and it is not disabled from the grub bootline, but the encrypted system always comes up with selinux disabled. Attempting to enable it with the command setenforce 1 fails, and to add insult to injury, the selinux administration-gui shows that it is enabled and enforcing. The cloned, now encrypted, system was cloned via rsync -aHXv, so the selinux contexts/attributes have been maintained as near as I can tell. I did have to disable selinux while performing the rsync of the /selinux directory in order to get it to copy and I am wondering if there was still some issue with this method.

I know some of you are running from encrypted root fs's and was wondering: Do you have selinux enabled and is it functioning properly? Any suggestions as to how I might jumpstart it or force it to run? Maybe I should boot into the system and uninstalling/reinstalling selinux?

Fedora :: Recovering An Encrypted Partition?

Apr 8, 2010

I have been using fedora 12 for last 6 months, recently I bought an external USB hard drive of 320 GB capacity. I made 2 partitions using the Disk Utility in Fedora. I encrypted the first partition as it was supposed to hold a lot of sensitive data, and yes it did have. Now I had to change my OS to AV linux for some audio-video editing work which wasnt being done properly on fedora due to some issue beyond my knowledge. now the problem is my encrypted partition is not accessible in my new installation. I see an empty space on my /dev/sda1. although no change to partition data has been done and the data on the second partition /dev/sda2 is easily accessible. when putting the drive on automount, is does not ask me for the password and neither does it show me the data. I have tried fdisk and sme other utilities but have failed to get my drive unencrypted.

Fedora :: Kernel Error With Encrypted HDD

Oct 12, 2010

i installed Fedora13 a couple of days ago and also activated the encryption of the hdd. But after updating my kernel yesterday, my PC doesn't boot with the new kernel. Choosing the old one still works, so I have still acces to my Files. But how can I use the new kernel? Or how can i completely and forever decrypt my HDD? The whole hdd is encrypted, so the boot and the home stuff isn't accesible without the key. Thats pretty depressing because I felt really intelligent when enabling the encryption

Fedora :: Can't Resize Encrypted / Home In LVM

Feb 13, 2011

Recently installed Fedora 14 64 bit on a hardware RAID 1 from distro DVD, and set up an LVM with an encrypted /home partition. I now need to resize (enlarge) the /home partition and have not been able to do it due to system-config-lvm telling me:

"Logical volume is not mounted but is in use. Please close all applications using this device (eg iscsi)"

I have tried doing this logged in as user, and also as root. I've tried with a Live CD, but an additional problem there is that the Live does not recognize the hardware RAID and tells me I have the same /home partition in two devices, which are the two disks in the RAID array, and refuses to resize.

I found this link:
< https://help.ubuntu.com/community/Re...ptedPartitions >
which details a rather complex process to achieve what I want, but I am wondering if there is an easier way ?...

PS... forgot to mention I have been able to successfully resize all other LV's within the LVM, so I am assuming it is the encryption that is causing the problem....
