  • Prevent query string manipulation by adding a hash?

    - by saille
    To protect a web application from query string manipulation, I was considering adding a query string parameter to every url which stores a SHA1 hash of all the other query string parameters & values, then validating against the hash on every request. Does this method provide strong protection against user manipulation of query string values? Are there any other downsides/side-effects to doing this? I am not particularly concerned about the 'ugly' urls for this private web application. Url's will still be 'bookmarkable' as the hash will always be the same for the same query string arguments. This is an ASP.NET application.

    What is the most efficient way to write the old-school: StringBuilder sb = new StringBuilder(); if (strings.Count > 0) { foreach (string s in strings) { sb.Append(s + ", "); } sb.Remove(sb.Length - 2, 2); } return sb.ToString(); ...in Linq?

  • How to loop an executable command in the terminal in Linux?

    - by user1452373
    Let me first describe my situation, I am working on a Linux platform and have a collection of .bmp files that add one to the picture number from filename0022.bmp up to filename0680.bmp. So a total of 658 pictures. I want to be able to run each of these pictures through a .exe file that operates on the picture then kicks out the file to a file specified by the user, it also has some threshold arguments: lower, upper. So the typical call for the executable is: ./filter inputfile outputfile lower upper Is there a way that I can loop this call over all the files just from the terminal or by creating some kind of bash script? My problem is similar to this: Execute a command over multiple files with a batch file but this time I am working in a Linux command line terminal. Thank you for your help, Luke H

  • Numeric operations over SHA-1 generated keys in C#

    - by webdreamer
    I'm trying to implement a Chord distributed hash table. I want to use SHA-1 as the hash function to generate node ids and map values to the DHT. However, I'll need to use numerical operations on the SHA-1 generated key, such as a modulo, for example. I wonder in which type of variable should I put the array of bytes I get, and how can I convert from one to another.

  • Multiple actions upon a case statement in Haskell

    - by Schroedinger
    One last question for the evening, I'm building the main input function of my Haskell program and I have to check for the args that are brought in so I use args <- getArgs case length args of 0 -> putStrLn "No Arguments, exiting" otherwise -> { other methods here} Is there an intelligent way of setting up other methods, or is it in my best interest to write a function that the other case is thrown to within the main? Or is there an even better solution to the issue of cases. I've just got to take in one name.

  • Why does this JSON.parse code not work?

    - by SuZi
    I am trying to pass json encoded values from a php script to a, GnuBookTest.js, javascript file that initiates a Bookreader object and use the values i have passed in via the variable i named "result". The php script is sending the values like: <div id="bookreader"> <div id="BookReader" style="left:10px; right:10px; top:30px; bottom:30px;">x</div> <script type="text/javascript">var result = {"istack":"zi94sm65\/BUCY\/BUCY200707170530PM","leafCount":"14","wArr":"[893,893,893,893,893,893,893,893,893,893,893,893,893,893]","hArr":"[1155,1155,1155,1155,1155,1155,1155,1155,1155,1155,1155,1155,1155,1155]","leafArr":"[0,1,2,3,4,5,6,7,8,9,10,11,12,13]","sd":"[\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\"]"}</script> <script type="text/javascript" src="http://localhost:8080/application/js/GnuBookTest.js"></script> </div> </div> and in the GnuBookTest.js file i am trying to use the values like: br = new BookReader(); // Return the width of a given page. br.getPageWidth = function(index) { return this.pageW[index]; } // Return the height of a given page. br.getPageHeight = function(index) { return this.pageH[index]; } br.pageW = JSON.parse(result.wArr); br.pageH = JSON.parse(result.hArr); br.leafMap = JSON.parse(result.leafArr); //istack is an url fragment for location of image files var istack = result.istack; . . . Using JSON.parse as i have written it above loads the Bookreader and uses my values correctly in a few web-browsers: Firefox, IE8, and desktop-Safari; but does not work at all in mac-Chrome, mobile-Safari, plus older versions of IE. Mobile safari keeps giving me a reference error msg: can't find variable: JSON. The other browsers just do not load the Bookreader and show the "x" instead, like they did not get the values from the php script. Where is the problem?

  • Howto ignore specific undefined variables in Pydev (eclipse)

    - by chris.nullptr
    I'm writing a crossplatform python script on windows using Eclipse with the Pydev plugin. The script makes use of the os.symlink() and os.readlink() methods if the current platform isn't NT. Since the os.symlink() and os.readlink() methods aren't available on the windows platform Pydev flags them as undefined variables--like so: Is there a way to explicitly ignore certain undefined variable name errors (e.g. os.symlink())?

  • how can I implement Comparable more than once?

    - by codeman73
    I'm upgrading some code to Java 5 and am clearly not understanding something with Generics. I have other classes which implement Comparable once, which I've been able to implement. But now I've got a class which, due to inheritance, ends up trying to implement Comparable for 2 types. Here's my situation: I've got the following classes/interfaces: interface Foo extends Comparable<Foo> interface Bar extends Comparable<Bar> abstract class BarDescription implements Bar class FooBar extends BarDescription implements Foo With this, I get the error 'interface Comparable cannot be implemented more than once with different arguments...' Why can't I have a compareTo(Foo foo) implemented in FooBar, and also a compareTo(Bar) implemented in BarDescription? Isn't this simply method overloading?

  • Javascript objects: get parent

    - by Dänu
    Hey Guys I got some question about nested javascript objects (is it me, google or is javascript quite poorly documented?). Now, I got the following (nested) object: obj: { subObj: { 'hello world' } }; next thing I do is to reference the subobject like this: var s = obj.subObj; now what I would like to do, is to get a reference to the object obj out of the variable s. Something like: var o = s.parent; Is this somehow possible?

  • I write bad wave files using Java

    - by Cliff
    I'm writing out wave files in Java using AudioInputStream output = new AudioInputStream(new ByteArrayInputStream(rawPCMSamples), new AudioFormat(22000,16,1,true,false), rawPCMSamples.length) AudioSystem.write(output, AudioFileFormat.Type.WAVE, new FileOutputStream('somefile.wav')) And I get what appears to be corrupt wave files on OSX. They won't play from Finder however using the same code behind a servlet writing directly to the response stream and setting the Content-Type to audio/wave seems to play fine in quicktime. What gives?

  • Error 'duplicate definition' when compiling 2 c files that reference 1 header file

    - by super newbie
    I have two C files and one header that are as follows: Header file header.h: char c = 0; file1.c: #include "header.h" file2.c: #include "header.h" I was warned about 'duplicate definition' when compiling. I understand the cause as the variable c is defined twice in both file1.c and file2.c; however, I do need to reference the header.h in both c files. How should I overcome this issue?

  • ASP.net MVC 2.0 using the same form for adding and editing.

    - by Chevex
    I would like to use the same view for editing a blog post and adding a blog post. However, I'm having an issue with the ID. When adding a blog post, I have no need for an ID value to be posted. When model binding binds the form values to the BlogPost object in the controller, it will auto-generate the ID in entity framework entity. When I am editing a blog post I DO need a hidden form field to store the ID in so that it accompanies the next form post. Here is the view I have right now. <% using (Html.BeginForm("CommitEditBlogPost", "Admin")) { %> <% if (Model != null) { %> <%: Html.HiddenFor(x => x.Id)%> <% } %> Title:<br /> <%: Html.TextBoxFor(x => x.Title, new { Style = "Width: 90%;" })%> <br /> <br /> Summary:<br /> <%: Html.TextAreaFor(x => x.Summary, new { Style = "Width: 90%; Height: 50px;" }) %> <br /> <br /> Body:<br /> <%: Html.TextAreaFor(x => x.Body, new { Style = "Height: 250px; Width: 90%;" })%> <br /> <br /> <input type="submit" value="Submit" /> <% } %> Right now checking if the model is coming in NULL is a great way to know if I'm editing a blog post or adding one, because when I'm adding one it will be null as it hasn't been created yet. The problem comes in when there is an error and the entity is invalid. When the controller renders the form after an invalid model the Model != null evaluates to false, even though we are editing a post and there is clearly a model. If I render the hidden input field for ID when adding a post, I get an error stating that the ID can't be null. Any help is appreciated. EDIT: I went with OJ's answer for this question, however I discovered something that made me feel silly and I wanted to share it just in case anyone was having a similar issue. The page the adds/edits blogs does not even need a hidden field for id, ever. The reason is because when I go to add a blog I do a GET to this relative URL BlogProject/Admin/AddBlogPost This URL does not contain an ID and the action method just renders the page. The page does a POST to the same URL when adding the blog post. The incoming BlogPost entity has a null Id and is generated by EF during save changes. The same thing happens when I edit blog posts. The URL is BlogProject/Admin/EditBlogPost/{Id} This URL contains the id of the blog post and since the page is posting back to the exact same URL the id goes with the POST to the action method that executes the edit. The only problem I encountered with this is that the action methods cannot have identical signatures. [HttpGet] public ViewResult EditBlogPost(int Id) { } [HttpPost] public ViewResult EditBlogPost(int Id) { } The compiler will yell at you if you try to use these two methods above. It is far too convenient that the Id will be posted back when doing a Html.BeginForm() with no arguments for action or controller. So rather than change the name of the POST method I just modified the arguments to include a FormCollection. Like this: [HttpPost] public ViewResult EditBlogPost(int Id, FormCollection formCollection) { // You can then use formCollection as the IValueProvider for UpdateModel() // and TryUpdateModel() if you wish. I mean, you might as well use the // argument since you're taking it. } The formCollection variable is filled via model binding with the same content that Request.Form would be by default. You don't have to use this collection for UpdateModel() or TryUpdateModel() but I did just so I didn't feel like that collection was pointless since it really was just to make the method signature different from its GET counterpart. Thanks for the help guys!
