It's happening in server side but how can I implement it client side.
I have a secure web site that is accessed by users who are in two different domains. Users from one domain using IE6 to access the site without any problem while users from another domain using IE7 get a popup message asking them to choose a digital certificate. It says "The web site you want to view requests identification.

This is not the issue in my case.
View 1 RepliesI 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?

View 1 RepliesI 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.

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 understand that we can easily secure the menu pages by enabling SecurityTrimming and putting role information in web.sitemap.
But my problem is that we have to use a 3rd party authentication piece. The ASP.NET application gets the UserId and roles from the authentication module.
I need to show/hide ASP.NET pages based on the incoming user's roles.
Is it possible somehow to use web.sitemap with these roles?
Or should I come up with my own way to map a web page to role/s?
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.
I have searched and could not find any article related to "How to implement Certificate Security in
production environment".
I could able to Create sample certificates for client and Server on my local machine and was able to authenticate my client app with the certificates . These certificates are test certificates.
How do I do this in Production. We have a domain certificate from GoDaddy which resides on the server. How do I create a Client Certificate off of that.
If I'm taking a password on a page, should that page be served via https and exactly how dangerous is it not to? I've tried googling this but every guide just says that ssl certificates "stop hackers seeing sensative data" with no real description of how they would do this or exactly how vulnerable your site is as a result of not having ssl.Could someone summarize how easy it is for someone to steal passwords on non-https pages? Should i even be considering doing a login page without one?

View 3 RepliesI have an intranet site that is used to pull several other intranet applications/tools and database info to one place.One of the most popular features uses iFrames and jQuery tabs to give a broad overview of activities, signal etc in a network node. Chrome and Firefox eat it up with no problems, IE will work if you override the cookie policies that restrict 3rd party cookies
without a valid p3p (what a worthless standard). IE also works if you already authenticated yourself on the individual sites and the session cookies are still valid.
Is it possible to log the user automatically into a third-party website if we have their details on record? For example, if I had a users facebook/hotmail username/password stored in my database, is it possible to use these details to log them into facebook/hotmail, then open up facebook/hotmail.com with them already logged in?
Basically my Client uses Basecamp for their customers and wants a way of automatically logging his customers into basecamp from their website without them having to go through the trouble of logging in again (after they've already logged in through my clients website).
I need to convert a web site using traditional ASP.Net login,membership/role with SQL to a custom system. I need to use a third party (CAS) authentication system while still using membership and roles to control access to content and User.Identity functions.What would be the best way to accomplish this? I use the <deny> and <allow> user throughout the site to control page access.

View 5 RepliesI'm working on a SharePoint solution which makes use of a third party dll (Telerik for Asp.Net Ajax - Telerik.Web.UI.dll) for rich experience. Since Telerik dll is a common assembly i have to deploy it to the bin folder of the webapplication instead of GAC. So here comes the problem.
WSPBuilder automatically deploys the dll to gac if the dll presents in the GAC folder. To deploy the telerik dll in bin i created the folder 80in and copied the dll there. I tried to build the wsp again and then went through the manifest.xml created. Great. The deployment target for the dll changed to WebApplication and wspbuilder was smart to create the cas policy itself.
<CodeAccessSecurity>
<PolicyItem>
<PermissionSet class="NamedPermissionSet" version="1" Description="WSPBuilder generated
[code]....
But Wspbuilder was not smart enough to put the four part name of SharePointPermission IPermission class. But i learnt that CAS actually requires the four part name. So i decided to make use of the -CustomCAS command line option of wspbuilder.exe to pass my custom cas policy file.
Here is my custom policy file -
<IPermission class="AspNetHostingPermission" version="1" Level="Minimal" />
<IPermission class="System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Flags="Execute" />[code]....
After i deployed the wsp i verified
* the dlls going to bin
* the trust level changed to custom trust level
* custom policy file being added to config folder
But when i run the page i get the following error -
screen shot -
Error -Execution Permission Denied
I've checked my entire application for any assembly references of the dll. But i was not able to find one.
