View 2 Replies I need to validate a digital signature which consists of thumb impression,signature and tokenid which is in pendrive with a columns of a table in sqlserver2008 database. I am using capicom.dll in asp.net 3.5 using c#.
I tried but I am unable to do it.
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.

View 6 RepliesI 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 have never write code like this... so I am trying to explian what problem I meet here..
assuming I have 2 web service
one named WS1 another named WS2
WS1 (send data to WS2) → WS2 then WS2 (receive data from WS1 and do something then return result to WS1)→WS1
if I want to add digital signature between WS1 and WS2 so that WS1 connecting to WS2 , WS2 will recognize who is connecting by digital signature
what do I need if I want to do that? and how to do?
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.

View 1 RepliesI 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. When the global.asax file is created, no code behind is created, instead code is placed in the global.asax file and the global.asax.cs file is never created? Why is the option for a C# code behind file greyed out?

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?

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?

The signature or decryption was invalid
Description:
An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.

is there a way to find and insert a page event via intellisense so i can get a list of what is available and the signature is automatically created?
Currently I create a page_init but with no parameters ... unsure if this is correct or no?
With controls you can take a look at Properties and then Events and you get a list of all events.
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.
