View 2 Replies View RelatedI am having trouble with encryption/ decryption program. The program goes out and finds the file I want it to, encrypts it into a continuing series of a single repeated negative number, then generally decrypts(or should i say re-encrypts)it into a widely repeated character, different but same results every time.

I ticked the box for this when I installed Lucid, but how can I verify that it's actually performing the encryption/decryption?
View 4 Replies View RelatedI was wondering, what would be a good, open-source file format for a beginner in the field, like me, to start editing sound files? This file format would have to be well documented, preferibly open-source, lossless and, most of all, convertible to more popular file formats, such as mp3 or wav maybe. I would like to design my own sound effects through directly editing the binary sequence of a sound file. I imagine this editing would have the purpose of adjusting the voltage variations of the sound device's output in time. It would be perhaps something like a PC-controlled signal generator. I'm thinking I might be able to do this in linux with something like
Code:
$ dd if=mysound.raw of=/dev/audio
But then, which book or resource woule be a good and through explenation of the relationship between the bit sequence in mysound.raw and the signal function generated in the output of, say, my computer's sound card.
I have my home partition encrypted and would like to take the decryption out of the system. Such as when booting the PC it would say it can't find the keys so stop and wait for me to put my usb drive in to continue (reboot and try again). Is there some way to get something like this set up?

akonadi shows errors (self test) on every startup (on different setups and with different errors) that's very annoying, everything seems to work though, so i just want to get rid of that stupid message (why should an average user of kontact solve mysql problems?). decryption of mails is not working, because of a "wrong passphrase" (says so in the mail body). I was never prompted for a passphrase and kgpg decrypts the msg.asc fine, so its a kmail problem!? the spam / ham buttons are invisible. i added them to the toolbar with no effect (meaning, they are still invisible). Removing of other buttons works.

Now since 1TB 2,5" hard drives have been released and are payable I've thought about buying one. The most improtant issue for me when using a protable drive is security and data security. I found the "Western Digital My Passport Essential" with hardware encryption but the description says that only Windows and MAC operating systems are supported not Linux in anyway. My question is are there any significant diffetences between the WD hardware decryption or a truecrypt container/drive? And is there another program out there better for this job? I want to use the drive on Windows and Linux systems.
View 3 Replies View Related 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 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.
If you are interested, Java SE 6 Update 24 is available. The Check Java Version link in my signature will tell you if you are up to date or not. The Update Java Version link in my signature will tell you how to obtain and install the latest version. The 32 bit version install directions are on the left side of that page and the 64 bit instructions are on the right side.
Just remember to remove the current version before installing the new one as it says in the instructions. The remove instructions are below the install instructions. Also, in Step 9 - "Now you'll want to tell the system, that there's a new Java version available." See the note below it that says if you get an error upon entering the command once, enter it a second time. I have to do that and sometimes forget. Just thought I would mention that. These instructions are already setup for version 6 update 24, but they can be modified for any update and they will work. I have been using these instructions for a couple of years and they work.
How to install java and firefox java plugin on Ubuntu 10.10?
View 2 Replies View RelatedI try to install the java plugin but the java test pages show not installed. I have tried the openjdk-6-jdk package and the Oracle/Sun 1.6.0_26 version to no avail.
Is there some good instructions page someplace? I have yet to find a set of instructions that provides something clear that works.

That's the error I get. When trying to run a java app with the firefox plugin, the browser simply crashes if it's the 64bit java or tells me it's not installed if it's the 32bit version.
I'm at a loss as to what to do. I think it has something to do with leftover gunk from a previous version I misinstalled(Is that even a word?) Anyway, the only thing that google could come up with was a solution for windows which laid blame on Bill Gates for having a bunch of pf (java prefetch) files stuffed into c:windows for no apparent reason. The solution was to delete them, but I can't seem to find the java prefetch folder in linux. The method I used is downloading the rpm from java.com the rpm2tgz then installpkg then cp libnpjp2.so to firefox plugins folder.
