Ubuntu Security :: Generate Password / Encryption Keys For Password
Oct 22, 2010I know this has probably been asked too many times here but I need to secure my emails. Personal matters of course. But yeah. I use the program "Password and Encryption Keys" to generate a key to sign my emails with but I do not know what to do. To be blunt, I'm stupid when it comes to this. IF not, steps in creating a key? and giving it (my public key) to the significant other? Finding where both keys are? Implementing it into Thunderbird? If it helps any here's some extra information: Ubuntu distro: Ubuntu 10.04 Email client: Thunderbird
View 7 Replies View RelatedUbuntu :: Change Harddisk Encryption Password?
Mar 22, 2011I decided to go for an encrypted home folder. It's really really cool that ubuntu offers the encryption now out of the box!
However it auto generated a password for the encryption for me. While the password might be safe, it is impossible for me to remember. And writing it down on a piece of paper, which I would then carry around along with my laptop seems to make the whole encryption obsolete...
Long story short: Can you pinpoint me on how to change the encryption password?

Jan 18, 2011am fiddling around using an AES encrypted password which is stored in passwd.txt:cat ../passwd/passwd.txt
{AES}yTMWTrdbuPtCxikvv5udVDTQ70anBVVKvP+GPQEH1RY=Yet I like to interpret this password on the command line using svn checkout, so I do not have to type in my password ( which is visible on the command line):Exporting the variable SVNPASS reading it from the passwd.txt ( export SVNPASS=`cat <../passwd/passwd.txt`) won't work obviously as it interprets it as "text", so my question is, if there is a proper way to interpret this stored AES password so I can read it from the file?The alternative is to type in the password on the command line, but this needs to be invisible eitehr showing #, * or "hidden".
the last option is described: http://www.tech-recipes.com/rx/278/h...-shell-script/
Security :: Reading Encryption Password With Bash?
Nov 20, 2010I have two cryptsetup volumes with the same password that I want to open in a bash script, and I want to avoid writing the passphrase twice. I was thinking of using read -s. Is there any security problems with this?The other alternative would be to have a password file on a small partition encrypted with a passphrase. Then only give the passphrase and let the script open up all encrypted volumes using the password file. However this seems overly complicated. But is it more secure?

Mar 20, 2010When installing the latest Distro of Mint (I believe this is not much different, if at all, from Ubuntu as far as this goes) I chose to have my Home folder encrypted using the login password. This was a function of the installation. What I was wondering about was how secure this was and if I should maybe use something to do a better encryption or not.

Apr 10, 2011Quote: The importance of security should never be underestimated. The consequences of losing data can be disastrous for any organisation. For example, the loss of a single unencrypted laptop may have huge repercussions. This could include breaching data protection legislation with the risk of a significant fine, a loss in the confidence of an organisation, as well as the risk that sensitive data may fall into the hands of a competitor or third party with malicious intent.

View 4 Replies View RelatedUbuntu Security :: Cannot Get To Grub Menu After Full Disk Encryption?
Jan 13, 2010this isn't really a security question, per se, so feel free to move. It is related to full disk LVM encryption though. Full disk didn't work for me with grub2 after running dd to a remote server, so I downgraded to grub1. No biggie. However, I have neither grub or grub2 as selected in Synaptic.Let's say I forget which I have installed. How would I determine what version of grub is installed at the moment. I'm assuming it's somehow installed on in the mbr but not on the OS. I didn't mean to do anything funky. Is that the normal setup? I'm deploying these systems to users and want to be able to troubleshoot issues in the future (hopefully that will not be needed!) grub --version does not work because it is not installed.

View 7 Replies View RelatedFedora Security :: Remove Encryption From An Hard Disk?
Feb 24, 2009I was trying to install Fedora 9 on my new laptop that came with Win XP. I have selected the option to wipe out all partition and create a default layout with the Encryption option selected. But that installation got stopped on the middle, therefore I have started the installation again. This time it asked for the encryption password as expected but don't know why, its not accepting my password. I am 100% sure that the password is correct but it is not allowing me to enter into the hard disk partition section.
My question is, how do I remove encryption from my hard disk? I don't need to preserve the data, I just need to use my hard disk again. Is there any boot CD that allow us to format encrypted disks without prompting for a password?
Fedora Security :: Disk Encryption With Remote Passphrase?
Jul 28, 2009I have currently a file server that runs on Fedora 9, and all other PCs (mostly running Windows XP) access the file server via SAMBA. Everything works perfectly! However, lately a home invasion in my neighborhood got me thinking. If they take my file server, my data is not protected. So, I would like to implement the LUKS partition encryption (/home) which sits on a separate disk. However, I don't quite like the decryption process at boot time. In other words, I would like to wake up the file server (WOL) remotely, and when it's done booting, I would like to log-in using the other PCs and enter the passphrase remotely to decrypt /home. Is this possible using LUKS encryption (i.e., cryptsetup)? If not, what would be another alternative to what I am trying to do using a secure encryption (so that the data is safe from thieves)?

View 5 Replies View RelatedUbuntu Security :: Encryption, Luks, "auto"-mount, But Ask For Password?
Feb 14, 2010I know how to mount it manually. I've seen a howto on how to mount it automatically by loging in with the user, you type your username and password and it mounts your encrypted partition. But that's not what I want. My idea is to call cryptsetup and mount on boot, AND ask me for passphrase like when its loading the system, then if I don't type the right password it shouldn't mount /home, even though i type the correct USER password later when the system is loaded(and then I'd have an empty /home since my home partition wasn't mounted due to wrong passphrase).
This is what I tried: I added the commands to rc.local and I don't even feel like it was executed, no passphrase was asked. As a test if commands there were being executed, I tried simple commands lile mkdir /test and it worked. So commands there are executed, yet, no passphrase was asked to me, I looked on dmesg for crypt and found nothing, I pressed alt+ctrl+F1 desiring to find a passprhase-ask and again, nothing.
