i am wanting to put a list of common passwords on a usb stick, but i want the file to be password protected. I also need to be able to access it from more than one computer (all linux, maybe a mac too).

I'm looking to find out exactly how to go about changing the encryption method of shadow passwords from MD5 to something a bit stronger, like SHA. I've been looking around for a bit now and haven't found out how to do it. I've gathered that I'll most likely need to change the /etc/pam.d/system-auth file. Right now, there is a line that looks like this:
password sufficient pam_unix.so md5 shadow nullok try_first_pass use_authtok.I'm guessing the md5 should be changed to something else, like sha256. What else? I know I'll need to reset all passwords once the change is made, but I thought there was someplace else that controls how the passwd command encrypts passwords.
I am just wondering what encryption method the shadow file uses, so that I may be able to manually change it. I ask this because I am trying to make a web page that will allow people to change their linux password via a browser.
View 4 Replies View RelatedIs it possible to have two passwords associated with one account, one that is the actual one, and another one, a duress password, that upon entering gives a similar (desktop) environment with "decoy data"?
The idea is to have the bogus password go to an encrypted home drive that looks as if it were the real deal, but it is wiping particular sensitive (encrypted) data that is visible only with the real password in the background, so that the actual data that need to be protected are not compromised. While the person who unlocked the computer tries to find the information on it between all the rubbish files, the real files are securely wiped. The files are very sensitive in nature, so it's better to have then destroyed than have unauthorized people access them, in the event of that happening.
I happen to know that TrueCrypt has a similar option but that requires an entire decoy operating system (and I think that might be a bit conspicuous), but is there a native linux way to do it?
I just recently upgraded from 10.10 to 11.04, but using the classic desktop instead of unity, mainly because unity sucks big time, but that's a different story, anyway, when I used 10.10 I had a key setup for access to my remote SSH server, but now when I try to set up a new key using passwords and encryption, I get:- "Couldn't configure secure shell keys on remote computer", followed by:- '** (process:2532):WARNING **:couldn't open fd 27:Bad file desciptor' 3 lines of this with different process numbers then I got ''** (process:2535):WARNING **:couldn't open fd 27:Bad file descriptor: Permission Denied. Please try again'
I have not changed anything on the remote server at all. I can access SSH using PuTTy sucessfuly, but I want to set up a key using the ubuntu passwords and encryption key program, but since ugrading to 11.04 I can not do that for some reason.
I'd like to know if there's a simple way to create a LUKS encryption drive with different passwords? A real one that leads to one set of data, and another that leads to a whole different set of data. Is this even possible with LUKS?

View 2 Replies View RelatedI would like to be able to store all my important details and passwords in such a way that it is encrypted, easy to get the information out and is cross-platform. Basically, I am thinking that if I kick the bucket that I would like to make it as easy as possible for others to be able to access this information using a pre-arranged password.
Ideally I would like the files to contain the program that is needed to extract the data i.e. importantinfoLinux.sh inportantinfoWin.exe (Just like a self-containing zip). I haven't found anything along those lines.
The things I am currently thinking of is:
1) A password database program that is cross-platform like KeePass. WIth the bundle contining the relevant installers for win, linux and OS X and the database file.
2) An AES encrypted zip of the data with relevant programs to open it e.g. 7-zip on windows, peazip on linux and OS X
Has anyone got any thoughts on this? Any self-containing java encryption apps?
I'm trying to backup my old PC games so that I can finally banish their CDs to the attic once and for all. I've just been using the DD command to grab iso's of my games so far, while keeping their keys in a text file (see the DD command below). However, I just hit my C&C collection and I'm having some problems with some of the newer games like Renegade and Yuri's Revenge. I think they must be copy protected or something. 4 of my last discs have stopped copying at exactly 1.7MB (3 seperate DVD drives, 2 IDE, 1 USB enclosed). Can you guys think of anything else that will cause DD to fail at this location? Any ideas? I'd prefer it to be a command line option, as I'm trying to make things go as quickly as possible. Here's the command I've been using. code...

View 9 Replies View RelatedI have a lot of passwords and keys for FTP and SSH connections that I need to keep. When using the "Passwords and Encryption Keys" the Export menu is sensitive/disabled.
I need to back them up, amongst other things, as I'll be re-partitioning my hard drive which will most likely result in a fresh install of Ubuntu.
I am not very security minded...I'm aware of it, and always made sure I had up-to-date overall protection in Windows but firewalls, and the blasted passwords are largely a thorn in my side!When I got my iPhone last year I suddenly discovered password managers & "wallets" to keep all that kind of information in and syncable across different devices. My life got so much easier. Of course now I need to figure out encryption keys, and how they work (I'm clueless). I also need to find a program or system that I can move my existing low-tech info (mailnly user name & passwords) that will also accomodate the increased needs of Ubuntu security and still be sync-able. I started a little research weeks ago, but my current "wallet" only exports .csv so I quit since I'm going to have to do a lot of data entry whatever I go with.So here goes:
1) what is the difference (bare bones) between using an encryption key (e.k.) vs. a standard user created password? what situations are better suited for e.k.?
2) I have seahorse (default intall with Ubuntu I guess) but the only thing in it is Login under passwords which leads to a login keyring (?) and a drop-down list of about 6-10 of the gazillon passwords I use daily. The other tabs are for keys which I don't have any concept of.
3) I know FF also "remembers" user id & passwords as you choose to have it do so. Is that information transferable into seahorse or another program?
4)I'm also (today) getting ready to really set up my system for user names & security across my little home network. How can I integrate that into whichever program/app I go with to store my pwds and keys?
5)give me links to fairly current documentation on this stuff?
6) Any program/app recommendations.Pros/cons uses, what they can & can't do or be used for, etc.
Desperation has set in and hence you get to view a thread with this title. I think the title explains it all. Or, what can be done when packages are no longer available through the repository but installing them from RMP is boarder line crazy.
View 8 Replies View RelatedI do not have any shares setup on my home network so this has never been a big deal to me. My mother finally took enough interest in my operating system to allow me to dual boot 3 of her computers. Everything was up and running like a charm and then she asked "What about connecting to the file server?"
I click on "network" under nautilus and start clicking around - no where in here is the file server that every Windows system on the network can see (5 or so other systems with xp/vista/7 on them - so I know the share works). A small bit of time and some command life foo later I had hunted down and manually mounted the share and added and fstab entry for the drive so my mother would never have to go through that on her own.
That being said - did I do things the hardway here? Can someone please tell me there is an easy method that successfully detects and connects to samba shares without having to resort to CLI? Personally I do not mind doing this, but it is an issue when I am installing Linux for a beginner.

View 9 Replies View RelatedI'm looking into using fedora as my first Linux OS, read rookie, I have an old HP PC with a brand new hard drive. I downloaded the 'F10-i686-Live.iso' file and tried to boot from it. It brought up a Fedora screen with various boot options and a memory test. I did the test which completed a successful pass. I then tried to boot from it, it showed the horizontal loading bar which turned white, after which the screen went black. From there the screen switched from blank to 'lit up black' , sometimes it showed a cursor which was mouse responsive, sometimes it showed a blinking underline cursor in the top left corner of the screen. Eventually it just stayed blank. Any threads I've checked are irrelevant or refer to a more options or command line option that isn't on the setup screen. Have I the right file/method?

I'm trying to clean up an iTunes-sorted Music directory. For whatever reason, it contains a large number of folders that have album art, but no music. I'm actually more concerned about a safe way to test my removal batch, but I thought I'd paste everything I did in case it's useful to someone. Based on this thread, I came up with the following script:
Code:
#!/bin/bash
find ./*/* -type f -iregex ".*(mp3|m4a)" | sort | while read line ; do
echo "${line%/*}" >> file1
done
sort -u file1 > fileuniq

But I'm scared to just run this on my music folder. Is there any way to run rm in "test mode", so that I would just see verbose output, but it wouldn't actually delete anything? Failing that, does anyone see anything wrong with my plan?

View 1 Replies View RelatedI am investigating full disk encryption and have made a DD copy of the hard drive which has been encrypted, this DD file is stored on my computer for analysis.
First question is - Anyone know how i can access data in this DD file even though its been encrypted?
Second question - Is there a DD command where i can image the systems memory? I ask this because when a system is turned on, to get past the pre-boot authentication stage you need a password. From what i understand, this password will be passed in to ram when power is applied to the system. Making a copy of the memory will also copy the password?
I'm looking for a tool that can directly convert mp3 file to a swf file. Tried ffmprg - 'ffmpeg -i master.mp3 -ar 22050 -ab 32 -f swf -y -vn new.swf', output is as follows:
Output #0, swf, to 'new.swf':
Stream #0.0: Audio: 0x0000, 22050 Hz, stereo, 0 kb/s
Stream mapping:
Stream #0.0 -> #0.0
Unsupported codec for output stream #0.0
I found a way to perform this task using ffmpeg to convert the mp3 file to a wav file, and converting the wav into a swf file using swftools (wav2swf), although this is not a good option because the output swf file size is very big - for a 12mb input 320kbps stereo mp3 file, the swf file is 25mb. Also downloaded a free direct mp3 to swf conversion software, which had an output swf file - with the same 12mb mp3 file - of ~400kb.
The requirements I have from the tool are:
1. Can be ran from the shell.
2. Direct conversion, or an indirect one that will produce a small output swf file.
3. Suport for multiple file conversion is a plus.
