  • How do i generate random data with RSA?

    - by acidzombie24
    After loading my RSACryptoServiceProvider rsa object i would like to create a key for my AES object. Since i dont need to store the AES key (i only need it to decrypt on my prv side) i figure i dont need to store it and i can generate it with my public key. I thought doing rsa.Encrypt(byte[] with 4 hardcoded bytes); would generate the data i need. It turns out everytime i call this function even with the same data i get different results. So theres no way for me to recreate the AES key if its different everytime. How can i generate data with RSA in a way that i can recreate anytime i need?

  • Autoplaynig video/image gallery - with a catch

    - by Ran
    Looking for a (jQuery) video/image gallery to implement on my website, I've found many freely available option. However, I need one that, when in "autoplay" mode and gets to a video file, automatically plays an entire file, and only then moves on to the next image/video. Similar to what Picasaweb are doing when you ask to autoplay an online gallery of your images/videos. I have found, for example, this plugin: http://www.yoxigen.com/yoxview/. Notice that images 6 & 8 are actually video feeds, but when in autoplay mode, are treated just like any other image, i.e. - displayed for a few seconds then moves on to the next file... not what I need. Thank you in advance.

  • Using wildcard domains to serve images without http blocking

    - by iopener
    I read that browsers sometimes block waiting for multiple images from the same host, and I'm trying to do everything I can to speed up page load times. One caveat: I need to serve files over HTTPS. Any opinions about whether this is feasible: Setup a wildcard cert for *.domain.com. Whenever I need an image, generate an number based on a hash mod 5 of the filename, and append it to an 'img' subdomain (eg img1.domain.com, img4.domain.com, img3.domain.com, etc.); the hash will make any filename always use the same subdomain, and therefore the browser should be able to cache the images Configure a dynamic virtualhost record to point all img#. subdomains to /var/www/img I am looking for feedback about this plan. My concerns are: Will I get warnings when my page has https:// links to multiple subdomains? Is the dynamic virtualhost record I'm talking about even possible? Considering the amount of processing this would require, is it likely to even produce any kind of overall benefit? I'm probably averaging a half-dozen images per page, with only half being changed on each page refresh. Thanks in advance for you feedback.

  • Finder.app preview pane and QuickLook stretch some of my photos

    - by mcandre
    The Finder column view preview pane and QuickLook stretch many of my photos. But when I open the same photos in Preview.app, they look normal. Screenshot: For example, download this image (reaver.jpg), and view it with Finder's column view. Now view it with QuickLook. It renders correctly in every other application, so there's something going wrong in how QuickLook/Finder get the image dimensions. This problem started happening in either Mac OS X 10.8.1 or 10.8.2. Specs: Finder 10.8 QuickLook v4.0 (555.0) Mac OS X 10.8.2 MacBook Pro 2009 Also posted in Apple Discussions.

  • How do I mount a HFS+ dd image in OSX?

    - by Paul McMillan
    I had an HFS+ formatted drive that was going bad and wouldn't mount at all on OSX. I created an image using ddrescue on linux, and was able to save most of it. I can mount the drive and see the data just fine in linux using this: mount -o loop -t hfsplus dd_image mountpoint This doesn't work on my OSX system since hfsplus isn't a valid filesystem type. If I try: mount -t hfs image mountpoint It complains that it needs a block device. What's the fix here?

  • How to securely generate memorable passwords?

    - by Tim
    Whenever I need new passwords I use some tools to generate those, preferable memorable passwords, but I've been wondering how secure this might actually be. Using The xkcd random number generator is probably pretty bad, cat /dev/random is probably pretty good, but generating memorable passwords seems a bit more tricky. Whenever a program generates a memorable password, it only uses a subset of the total password space available, and it is not clear to me how big this space is. Of course a long password should help in this case, but if the `memorable' part of the program is too predictable, your passwords are not very good in the end. TL;DR: how secure are memorable password generators, given the fact that `memorable' passwords are a subset of total password space? Some tools I know of: pwgen -- seems ok, but passwords are not too memorable Mac Password Assistant - generates memorable passwords but it is unclear to me how this works.

  • Using tshark to generate traffic logs every X seconds

    - by Sridhar Iyer
    I'm trying to use tshark to maintain a running history of all the packets that are going through an interface, for say 30 seconds. I want it to be human readable. This is a linux machine, and without mucking too much into the netstack source (which I can do if push comes to shove), I was wondering if I can use tshark to this. tshark has a -b duration:10 -b files:2 which I can use to generate a rotating set of 2 files, but I don't know which format it is printing the file in or how to read it.

  • Simple Workstation Imaging Solution?

    - by user23087
    I need a fairly cheap imaging solution for Windows XP corporate desktops. Ideally, I'd be able to set up a desktop exactly as we want it, create an image, deploy this image to a server, then boot a new desktop to a CD/USB Drive/Network and quickly set up the workstation. Ideally, each computer would also have a unique workstation name. Any ideas? Right now I'm using a custom built Linux DD solution, but it's slow, not network-based, can't image multiple computers at the same time as there's only one copy on a USB drive, and can't uniquely name the computers. Thanks, Will

  • Create a Windows Image for Deployment

    - by Kiranu
    In my company we have 8 laptops that we use to deploy on the field. These machines get assigned to a user for a certain time and run Windows Vista. All the machines are the same model. After the machine is returned, it is company policy to completely format the machine and go back to a predetermined configuration. Right now, what we do is we use the recovery utility in the laptop (we are a small shop so we use the OEM Windows license that the laptops come with) and manually uninstall and change the configuration in order to bring it to our baseline config. I know that there are ways to create an image that gets copied to the hard drive with a specific configuration and with specific software installed (thats what OEMs do right?). I'm looking for a tool or a tutorial or something that explains as simply as possible how to create such an image. Thanks a lot

    - by Iceking007
    Hello I am trying to Burn a disk let me catch you up where I am at as I have a very SPECIFIC question and it may be difficult to explain but I will try to keep it simple: I have software already in an ISO file; I am using Daemon tools on a Windows based PC What I am wanting to do is create the actual Picture (not disk image file) that will show up on the Disk drive when I insert the disk Eg: if you put microsoft Office 11 in your comp. you open up My Computer to view all your HD and Disk drives you will see the image that microsoft put on the disk which is a silver CD and the Microsoft Office logo on the top corner. I would like to know how to edit my current ISO file or what I need to do in order to put "A PICTURE" or "AN ICON FILE" on the CD/DVD so that when I insert the disk into any PC it will show up with the PICTURE OR ICON file I chose and look proffessional. Thank you for your time

  • GIMP: change the exact color on the image - OK, but transparency disappears

    - by Haradzieniec
    There is no problem for me now to change color for pixels of the same color: I click on "Select by Color Tool"(Ctrl+O). The pixels of the same color are selected now. Then I press Ctrl+,. The selected pixels are white now (the white color is taken from a foreground color). The problem is the transparency. The green color I want to change to the white one has transparency. Once I use my method, the transparency disappears so all my-green-color with any transparency becomes white and without transparency. How do I keep the transparency by using my method? My picture is in .png format.

  • How to convert an image to a .dwg file

    - by erikric
    My girlfriend is making an art project where she is having an image printed and cut out on a metal plate. The firm responsible for doing this is demanding a .dwg file (and something called polyline; some sort of setting maybe?). Neither of us have heard about this file format, and I find the information about it quite confusing. Most pages seem to link to some schetchy "FooToBarConverter" software, that I frankly don't trust. Could someone please enlighten us on what we need to do, or point to some safe and preferably free software that could do this? (An explanation of the dwg format and the polyline thing would also be much appreciated)

  • Virtual Box state not saving upon restart/reset/shutdown - reverting to an earlier state

    - by user638756
    Every time I restart/shut down my VM in VirtualBox (image is Ubuntu 10.02), whenever I start it back up, it reverts to the state it was in after I installed Guest Additions. This is extremely frustrating as every time I make progress on a project, whenever it restarts (mostly from crashing), I have to redo mostly everything. Is this a known problem with Guest Additions or with Virtual Box in general, and if so is there some solution?

  • Partimage and autocheck problem when restoring Windows XP from image

    - by Xolstice
    I'm trying to create an image of Windows XP and clone it to several partitions on the same hard drive using Partimage. I seem to be running into a problem when I restore the image onto another partition - when I boot into the OS from the partition I just restored, it brings up this message during the boot sequence: autochk program not found - skipping autocheck, and then after this, the OS reboots the PC and the whole process repeats itself in an infinite loop. After doing some Google search, it is suggested that this loop was caused by the partition being hidden or the mountmgr.sys file is missing. I checked my configuration and verified that this was not the case. I'm just wondering: Has anyone else experienced this and is there a solution for it? Is this what happens when you try to restore the image to a different partition on the same hard disk or is Partimage itself the problem? Should I be trying out a different partition cloning software?

  • How to boot floppy image without floppy drive?

    - by Teddy
    Suppose I have a 1.44 MB floppy image with, say, a BIOS update, and a server with no floppy drive. How do I boot this image on the server? Without getting a USB floppy drive, that is. I tried copying the image to a USB drive (raw copy using dd), but it didn't boot, it just said "No kernel" and contiued booting on the HD.

  • How do I find funny pictures?

    - by Hanno Fietz
    No, not lolcats. And I'm not really looking for a specific site, either. I have often wished that I had some funny picture to illustrate a presentation, a website, a post, an email, or something else. Google image search and stock photo services have hardly ever helped me, although that may be because I'm doing something wrong. Jeff Atwood seems to have no problem to find funny pictures for his codinghorror and stackoverflow blogs, as well as for the error messages on the trilogy sites. One of my favourites was this elephant. Other bloggers also seem to be quite good at it. I'm wondering if I simply lack the creativity or if there's sources or methods I don't know about. I could think of the following ways to get pictures, but I'm not sure whether this is really "how they do it". keep a collection of pictures that you stumbled upon and liked (takes quite some time to build up to a proper library), when you need a picture, there's one in there maybe have pictures on paper, too, like from magazines or ads. when you are looking for a picture, search online (Flickr, Google, stock photos). This has never really worked for me, I don't know why. produce the pictures yourself, i. e. have a good library of source material or find some online and apply some creativity and suitable software. I could imagine that this could work well once you have the practice.
