I am going to start to work with electronic signatures for a website for my company. Whats best practices and/or implementations. Note, I am not asking for anyone to spoon feed me code. I would like to be able to use a usb signature pad and submit the signature to the website with it.

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.
1). user will upload a pdf file
2). and then will upload his signatures
3). embed the signature in pdf file
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 1 RepliesIn the application a user will upload a PDF file and then upload a personal signature created using a digital pen. How can I embed this signature in the pdf file?
View 2 RepliesI have problem to create digital signature. I created console application and it works there but when I want to run it at server there is exception. It looks like I have problem with reference to the file.
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?
Currently I am developing a memo application for a company that each director needs to sign the word document as approved or disapprove. I have scan copy of each director as image in my DB.
The signatures and date will be appended at the bottom of the doc page
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?
We are using wse 2.0 sp2 and I recently installed a new webservice as windows service previously it worked fine but once I re-installed it as windows service it throws an error
The signature or decryption was invalid

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 have a web control with a text box configured like this:

I am unable to get it to hit the method in my service with a signature like:
public
string[] GetOrganizationNames(string searchText,
int count)
but it does get to the method if I change the signature to:
public
string[] GetOrganizationNames()
For obvious reasons the second one will not do me any good. I have verified the data coming back from the method is good.
my goal is to develop a signature generator for board-signatures.
I have my database with a few information about characters in a online-game. A user should get a image-link, and should be able to write it in there board-signature. In the Image should be a link to my page and a few information from my database. Here is an example, which I want to build for another online game:

How to do that in ASP.Net / C# / .NET 3.5?
I have two methods that do the similar thing. There are small differences here and there, which I can control by passing arguments to them when I call them, so I can effectively merge them. However one returns a string, and the other one an ArrayList. On the top of my head, I could merge them and return an Object, and then get the information I need. Is there a way though to return multiple types in the method's signature? What's the proper way to implement this?

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.
i want to send email with digital signaure usind digital certificate
View 1 Repliesi have a dynamic data layer, i.e every user can add custom fields to database tables, so i need dynamic methods in my application.
i know i can use params to specify a variable number of parameters for a method, but the gridview in asp.net looks for a method with the same fields it is updating, i.e if gridview updates fields :name, age, phone, email(suppose email is a custom field of a certain user i.e it doesn't exit for another), and the object data source calls the update method with signature : (name, age, phone, params object[] custom_attributes) an error is generated that the gridview can not find the method with the signature(name, age, phone, email)
I have asp.net page running under MOSS2007 and there is Access Denied error at signing (signedXml.ComputeSignature()). The code works as normal .net web application but it does not work under MOSS.
Access is denied.
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 need to capture and save user signature to database on asp.net webform.
I found this plug-in: [URL]
I downloaded the example project and it is very simple, it has only fews file but I could not understand.
demo here: [URL]
How do I use this on a web-form page, let say on "save" button click postback event, it will save the imageurl of the signature under this format:
data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAApIAAAE+CAYAAAA+
vvBuAAAgAElEQVR4Xu3de6w1XV0f8K8WvIEiFTAKXhBrab0AxUraaFET0xYxSGrrpSb
UahsjbcUoXhKtIiaaSFSSojHRUP7w0rQGKbZJ00ahN.........
to a string variable so I can save this string to database?
Also how do I use 2 signature fileds in a same page, because I want to capture signature of 2 users.
I'm helping out a colleague on this one so if I'm missing some details that's why.We have an asp.net 3.5 web application calling a WCF service. Originally the app used a "Web Reference" to register the service however after having some trouble and burning an incident with Microsoft their solution was to replace the "Web Reference" with a "Service Reference" to the WCF service.This is great except the problem is that when we create a Service Reference, the method signatures are different than they were when a Web Reference was used.From what I've read this may be expected, however in our case this would mean some significant changes to the application and of course it was due yesterday...so......I'm wondering two things:Is it normal/expected that method signatures will change based on the reference type?Is there a way to create the Service Reference that will generate method signatures identical to the original Web Reference?
View 1 RepliesI need to take a picture and submit it to my facebook wall automatically including text if included. Is there a way to do this from asp.net? I do not want to use any user interface - I want this to be automatic. As new pictures come on my server I want to post them right then.
I looked at the developer pages of fb but can't find anything that is more automated. What is the best and easiest way to submit the pictures?
