Is there currently a GUI for GPG encryption? I know Ubuntu used to have one. It's no longer installed by default and I tried to install the seahorse plugins so I could just right-click on a file and click encrypt, but it's not available. I've already tried right clicking in different folders and everything.
View 6 RepliesI am building an active directory and using BIND9 as my DNS. To allow for secure dynamic updates from the domain, I am enabling GSS-TSIG as detailed here and here. Unfortunately, some of the commands and configurations used here seem to be depreciated, at least in the newer versions that I'm using. My issue is one of keytab encryption. I generated a keytab using ktpass.exe on the Windows Server 2008 domain controller. I have tried DES/MD5, AES128/SHA1 and AES256/SHA1, each have been turned down by ktutil on the kerberos server (FreeBSD). Each time, it outputs the following error: ktutil: AES256/SHA1*: encryption type AES256/SHA1* not supported *Respective to encryption used.
I cannot find a list of suitable encryption schemes that ktutil will accept. The FreeBSD handbook details a means of producing a keytab file, but I'm not sure how to configure the Domain Controller to use the keytab.
I have PDF files secured using 256-bit AES, requiring a password to open the file (Acrobat 9 or greater)
I can use Foxit Reader or Adobe Acrobat just fine on Windows, but I can't view those PDF's on Ubuntu or Mac OS X. What PDF readers for OS X and Ubuntu support 256-bit AES?
I can't get U1 to work. I removed my machine from U1 site and then I tried to add it again, but the login screen won't appear. I purged Ubuntu One completely (config files, local cache, packages, etcetera) but there's one thing I can't do: deleting myencryption key.It's simply not there and since I can't remove it, I'm not able to add my machine to U1.It happened in Maverick so I upgraded to Natty, but the problem is still there.

The server is on Ubuntu and the Windows client are both on the same switch on a private network, and won't ever be use over public internet. I see in the client that I can disable encryption, but how do I do it in the FreeNX server end?

if i try to use a static address then the laptop seems to connect but I cannot ping the router or get to the internet.If anyone has any ideas I would be grateful, I would rather use WPA than WEP.My iphone connects and this netbook connects with Windows, so I know the linksys is not at fault.
I have a server with Apache2 and I would like to use encryption to prevent eavesdropping POST requests and similar. I've had success using SSL with a self-signed certificate, but this will of course generate huge warnings from the web browser. It's no problem for me when I'm connecting to the server as I know what to expect, but any other user who sees such a warning will surely leave the site unless I have personally explained the procedure.
Is there really no way to encrypt HTTP without having to use certificates? I know that this is supposed to provide security by identifying the server,but my point is that an encrypted connection without a CA would in no way be inferior to one that sends passwords as plain text.

I am going to set up a Ubuntu installation on an external USB drive as per CS Cameron's advice in[URL]..I will put home on a separate partition and encrypt it when I reinstall Ubuntu using the inbuilt encryption in Ubuntu 10.04. (My data will be on there so it should be safe for a short while if the disk goes missing)
My question is: If I plug the USB drive into another computer which runs ubuntu (but cannot boot from USB), will ubuntu running in the "normal" way installed on the local fixed hard drive, be able to access the data on the partition if i tell it the password?
I am looking for some software (not Tryecrypt) where I can just right click a file and it will encrypt it for me. It would be nice to unencrypt on Windows but not essential.

View 2 Replies View RelatedI installed ubuntu 9.10 to a fresh partition on a HD that already contains a windows xp. During the install I opted to Require my password to login and to decrypt my home folder, (don't ask why, I regret it already). The install went well, I think, but when it came to reboot time I wanted to check that I could start windows xp from the new grub boot loader. Windows started fine so I rebooted again to try my new install of ubuntu. Now the system seems to get stuck at the little spinning wheel icon. I tried to boot to recovery shell but after entering my name and password I get:
Unable to cd to '/home/myname'
I rebooted using live cd. And mounted the file system as root. Now I have chroot ed into the system but that's as far as my knowledge gets me. I have googled to find the next step but am not finding a clear answer. I have found this [URL]. And here I see I should have seen a screen entitled: Record your encryption passphrase. But I didn't get to that screen. So is there any elegant solution? or am I destined to wipe the install and start again? Perhaps this problem is connected to the bug mentioned here [URL]. Optional encrypted partitions must be marked bootwait in /etc/fstab
In addition to the above, users who have configured any encrypted partitions in /etc/crypttab to start at boot time (i.e., not using the noauto option) should make sure that the filesystems on these volumes are listed in /etc/fstab if they are not mounted at a standard system mountpoint. Failure to do this on a desktop system will lead to problems from the X server and cryptsetup trying to control the console at the same time. At best, this will prevent the user from seeing the passphrase prompt; at worst it will also cause the X server to spin and consume 100% CPU. (430496)
I'm not sure, my /home is not on a separate partition.

I have configured vsftpd on Ubuntu 9.04 and it is working fine. I have configured non-anonymous ftp so that only few of us can acces that ftp. Now I want to secure it using ssl. so I have changed the vsftpd.conf file and entered the following lines in it.

After the restarting the service now when I try to connect to the ftp server it gives me this error. 530 Non-anonymous sessions must use encryption.
I just tried to create a qemu qcow2 image with encryption:
Code:
qemu-img create -e -f qcow2 foo.qcow2 100G
Formatting 'foo.qcow2', fmt=qcow2 size=107374182400 encryption=on cluster_size=0
It's some time ago I played with qemu, but I think it's supposed to ask for a password.
If I start the image with
Code:
qemu foo.qcow2
it just says 'QEMU [Stopped]' in the popup terminal window. It starts normally without the encryption option on qemu-img.
Is encryption known to be broken? Is this perhaps specific to qemu with KVM patch or to the 64-bit version?

I have a DELL Latitude E6410 64bit with Core i5. My goal is to have my Windows 7 encrypted and my Ubuntu 10.4 unencrypted and to be able to boot them both. So here are the details. I installed windows 7 first. Then I installed Ubuntu and Grub was in the MBR. Then I started TrueCrypt 5 from Windows 7 and encrypted the system partition, not the whole drive! So the TrueCrypt loader overwrote the GRUB in the MBR. Now when I start my computer, I see the prompt for password from the TrueCrypt boot loader. If I enter my password, windows is loaded.
The other option at the beginning is to press Esc and that should offer me other boot loaders. Well, on my DELL there's this Recovery partition and it boots immediately. How I can integrate the Grub in the process. I know, that there are many howto-s on the internet about this problem, but I haven't found a solution for grub2 and windows 7! It is indeed different, because GRUB does not have menu.lst any more and Windows 7 does not have boot.ini!
Here some more info about my partitions:
Code:
/dev/sda1 fat16 DellUtility
/dev/sda2 ntfs RECOVERY
/dev/sda3 unknown
/dev/sda4 extended
- /dev/sda5 ext4 ubuntu
- /dev/sda6 linux-swap
Windows 7 in installed on /dev/sda3 and is encrypted, that's why the file system is unknown.
Ubuntu 10.4 is installed on /dev/sda5
I know of three options to deal with the problem:
Solution 1
Install GRUB to the PBR (partition boot record) of the linux partition - that's /dev/sda5 in my case. Then, it should be possible to load GRUB when you press Esc in the TrueCrypt boot loader.
solution 2
Make Windows load Linux. Copy the PBR of the linux partiotion to a file and copy the file to windows. Then add an entry in the windows loader to include the linux loader file.
solution 3
Make GRUB load TrueCrypt's boot loader. Make a backup of the MBR (containing the TrueCrypt's loader). Add Truecrypt's MBR as a chain boot loader in GRUB. Finally, rewrite the MBR using this new GRUB.
I did install GRUB to my PBR with
Code:
from the live CD:
first mount /dev/sda5 to /media/ubuntu
sudo grub-install --root-directory=/media/ubuntu /dev/sda5
I also tried with
Code:
from inside ubuntu:
> grub
grub> find /boot/grub/stage1
hd0,4
grub> root (hd0,4)
grub> setup (hd0,4)
grub> quit
After one of these, I am able to boot my ubuntu after restart. But then I reboot and load windows, reboot once again and press Esc in order to try to boot ubuntu again, and then I don't see the grub loader list, but the "grub> " shell prompt instead! I thought that I will be able to see the grub loader also after many restarts, not just the first time. Why this configuration "breaks" after 1-2 reboots? Maybe the problem is that my ubuntu is on an extended partition (sda4)?

I am currently running 8.10 with full-disk (excluding /boot) encryption. I am going to be installing 10.04 on a new laptop, and I was wondering whether it supports multi-factor authentication. Specifically, I would like to have a keyfile on USB/SD memory that is required, in addition to the password, to decrypt the disk. Anyone know of a guide out there? So far my searches have turned up nil.

View 5 Replies View RelatedI've been using GPG keys for about a year now to send encrypted emails to family. But now I want to try and understand more, mainly on signing keys. I've read a ton of stuff, but not fully grasping the concept. So I thought I'd check my understanding people here. Please let me know if I'm wrong on something.
Signing keys seems to be just signing someone else's public key with my private(public??) key. Does that mean I don't sign my own keys? Or should I? There seem to be lots of keyservers out there, mainly I keep hearing about the MIT one and the ubuntu keyserver. Does it matter where I upload my public key? Somewhere I read that once you upload it once, it will slowly make its way to other servers. How is that possible. If someone signs my key on one server, will that also get pushed to other servers?

How to disabling Encryption keys ?(ubuntu 10.10)
View 3 Replies View RelatedI don't care for domain 'authentication' by an "Authority". I don't trust no one, so CA's to me are as trustworthy as the gypsy in the park.
I can use a self-signed certificate, but the problem is most browsers makers are Fn idiots that say the connection is not secure, when it actually it, but because I did not folk out cash, it makes my website look bad.
I can understand the need for a 3rd party to verify the domain host to prevent man in the middle attacks, but I do not care for this.. and browser makers should take more responsibility and introduce different padlocks for types of authentication, rather than saying "this connection is encrypted, but not secure because its self-signed". What a load of horse s***!
How many times does people stop to read certificate authorities? I sure don't. I only care weather or not the connection has been encrypted.. so, I am looking for a way for simply providing encryption for my website.
From what I understand, when you submit a CSR to a CA, it includes the private key, meaning that the CA would be able to see the encrypt data, should they get hold of it. This is not acceptable for me.
Is there anything other way to use encryption other than the SSL model that is used typically amongst HTTPS browsers today?
