Security :: How To Implement Digital Signature

Aug 12, 2010

I am new to digital signature. I have a web application developed in asp.net 3.5. In one of the module of this application I am generating pdf file and storing it on the server. The users must be able to choose a pdf file and digitally sign it with a certificate stored locally (either on their machine or in a smartcard). I do not know whether I should pass pdf file to client place to sign it or I should send Certificate object to the server.

Security :: How To Verify Digital Signature Of JAR/APK

Feb 19, 2010

I posted this previously but it ended up in Languages/C# rather than here. I'm not sure if I chose the wrong forum or the admin moved it. I wanted it in here so I'm re-posting it:

I have an APK file (android application archive, same as JAR file format) that I need to determine whether or not is signed, and if so, extract the certificate info.

The JDK provides a command line tool to do this:

jarsigner -verbose -certs -verify file.apk

I'm trying to determine if there's a way using the Security classes to accomplish the same thing in C# code.

I am currently having trouble with verifying the digital signature in a excel file. The digital signature is used to sign the Macro so that it is possible to authenticate and ensure that no one has tamper with the Macro.

Currently, I am able to check that the excel file is digitally signed. However, I can't seem to be able to verify and ensure that the digital signature is authentic. I'm using asp.net 3.5 with vb.net.

Does anyone have any experience with importing meta data files from Ping Identity into an ACS provider?

I'm logged into my Ping Identity admin system, all fine, no problem. Then, when I export the idP file... no digital signature is included within it and thus I cannot import this file into ACS as it complains that there's no signature included.

I have an asp.net application. I want to add a global.asax and global.asax.cs file to my project. In the IDE when I select to create a new global.asax file, the option to create a CS code behind file is greyed out.

C# - Can Use Digital Certificates With SilverLight Webpages

Sep 3, 2010

I am fairly new to web development and have never used Digital Certificates before. I assume using a digital certificate on a silverlight web page is the same as using one on any other web page, but i thought i should check. There are a few example of digitally signing the .xap file on the internet, would it then be a case of simply buying the certificate (from verisign or somewhere similar) and distributing it to customers?

MVC :: Different Actions Having Same Signature If Don't Want To Pass Action Name?

Sep 6, 2010

I am having one controller Test having following actions

(1)public ActionResult ABC (string parameter1, string parameter2)

(2)public ActionResult XYZ (string parameter1, string parameter2,string parameter3, string parameter4)

i have added following html.routelinks

<%= Html.RouteLink("ABC","ABC", new { parameter1 = 100, parameter2 = 200 } )%><br />
<%= Html.RouteLink("XYZ", "XYZ", new { parameter1 = 1000 , parameter2 = 2000 }) %>

last two parameters in XYZ action are optionals so i have not passed them in Html.routelink

routes.MapRoute("ABC", "Test/{parameter1}/{parameter2}", new { controller = "Test", action = "ABC", parameter1= 0,parameter2=0 });

routes.MapRoute("XYZ", "Test/{parameter1}/{parameter2}/{parameter3}/{parameter4}", new { controller = "Test", action = "XYZ", parameter1=0,parameter2=0 ,parameter3=UrlParameter.Optional,parameter4=UrlParameter.Optional});


In above senario in both cases same route "ABC" is called eventhough i have clicked on second Html.routelink. can anyone solve this issue ? how can i route according to route name instead of number of parameters?

Security :: Create Digital Watermark In Images?

Jan 28, 2011

I am doing a project on digital watermarking. This is the process. The user will choose his image file to upload, chooses his image key(either from the visual studio gallery-folder name is Image Key, or he chooses his own from the directory).

He enters a password, and this password will be embedded into the image uploaded.

Next, there is an option to digitally watermark the image (This is where I am having problems - stuck with the codes)

Here is the work so far, and I couldn't get any further.

FileUpload UI + code behind
