I'm building a web application that most allow the user to digitally sign PDF documents with certificates installed in the client machine.
The document, once signed, should be posted back to the server, where it will store the signed version.
The server is running Classic ASP/ASP.NET
we are trying to digitally sign pdf on a browser probably using js. the only good link i could find is this [URL] have you found the answer to this problem ? did you successed in that task.
View 2 RepliesWhats the best way to digitally sign a file server side with .Net before offering it for download via an asp.net based web site
In addition how do I trigger checking of the signature and hence prove the file has not been tmapered with during the download process in a web browser
There is an ASP.NET application www.example.com/APP. From within the application several documents - for example office documents DOCX, PDF, etc. - can be opend. They are accessed via some virtual directory as in
www.example.com/APP/VIRTUAL/letter.pdf.
Of course, the documents may only be accessed from within the application, after the user has been identified succssfully. Some documents may only be opened by some privileged users. It should be impossible to open letter.pdf by simply entering the above url into a browser
I am thinking about the following...
The name of the virtual directory is kept secret. After the user has successfully logged into the application, some secret is created. The secret contains the user's ID and some time information (valid from / until). Then, if a document is to be referenced from within the application, the url www.example.com/APP/<secret>/letter.pdf is referenced. In IIS the secret is checked. For this, some of my code is called, when serving a request. If successfull, the url is rewritten as www.example.com/APP/VIRTUAL/letter.pdf. I tried several components, such as the IIS URL Rewrite, IHttpModule, IHttpHandler. Unfortunately, I did not yet succeed.
I want to implement single sign on in my asp.net web application. Scenario is something like below:
user will get registered / sign up at "account.example.com"
there will a link to "professional.example.com"
when user goes to this link (step 2), they must remain logged in over here.
I have an application with several web pages. I am developing securities for those web pages.
Thus, I would like to create a dropdownlist that reflects the various aspx pages, or files inside my application. I would prefer that it reflected the aspx pages only and avoid the .cs files and config files and etc. I'm not even sure that this is possible. Is it? If so how? if I can't filter like that I would still take it.

View 10 RepliesI need to create a single sign-on structure and my question is: is SSL a must?
Details:
The application will have a link to my web application. When the user clicks that link, their local username will be passed to my web app at which point a look-up in a mapping file is done. If that local username exists in the map, then the user is logged in. If not, then the user will be prompted to enter their network username and password, and when authenticated, an entry in the map will be created.
How do I ensure that user is who they say they are and not Joe Blow from off the street sending in an HTTP POST request with that username?
Do I have to use SSL (and if so, what does that entail)? Would adding a salt and encrypting the username be sufficient? Maybe locking it down so the source IP has to be within a controlled range?
My web app runs on IIS 6/7 and uses the ASP.NET MVC framework, if that is important.
I am trying to use the concept of Single Sign On (SSO) in my asp.net application.
for the purpose i have created a main domain say
mydomain.com.
now i have 2 subdomains
sub1.mydomain.com & sub2.mydomain.com.
I am running these very fine. But now I want to have a SSO for my domains. For the same have
googled lot and found some stuff such as adding machine key to web.config and specifying domain names in cookies.
But it is not at all working for me. when I specify the domain name for cookies i am unable to sign out.
I am using FormsAuthentication in asp.net.
Following is the code I have in my web.config.
[Code]....
I have the same code in web.config of each domain.
I have placed the code for each domain in different directory on my website.
for ex. mydomain.com ---------> F:/HostedSites/mydomain
sub1.mydomain.com ---------> F:/HostedSites/subdomain1
sub2.mydomain.com ---------> F:/HostedSites/subdomain2
my Authentication code is
[Code]....
and sign out code is
[Code]....
Can anybody tell me where exactly I am wrong ? what changes do i need to do at server end also.
I am checking this on my testing domain ie. mydomain.tv. can this be a problem ?
We migrated our web server to window server 2008, IIS 7.
We have single sign on application - that we login through one application called "users" and then no need to login to other applications, they all use the same machine key and cookie.
it works fine when all then applications under the same application pool.
but we have one application that is asp.net 2005. (the rest are asp.net 2003) the user application is in asp.net 2003 and that other application is in asp.net 2005.
so each application is in a different application pool. -
one pool to asp.net 1.1 and other pool to asp.net 2.
when I run the asp.net 2005 application
I get the login page and after I login I get the following errer:
HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
Requested Url: /users/Unauthorised.aspx
Important: If I switch the "user" application (the login) to work under the same pool as my asp.net 2005 application, then it works fine with the asp.net 2005 application,but I get the above error for the asp.net 2003 applications
All this happened after we switched to IIS 7 Windows 2008, with IIS 6 it works great!

I have 3 DIV Tags in a web page.
When I click Print All button in the web page, i have to store the contents of 3 DIV tags in rich text format file. Then i perform some codings for modifying the contents of 3 DIV Tags. Similarly i have to store the contents of them in same rich text file (appending to a file after page break) and so on.
1)I want To save Documents in sqlserver db by usnig asp.net with c#
View 5 RepliesI'm working with an asp.net application that produces large PDF documents from HTML. The content is perhaps complex (detailed grid type listings, css styled, running to 40+ pages) compared to typical usage. None of the libraries we've tried are performing adequately. Typically a 40 page document is taking upwards of a minute to render on a powerful multi-core machine.
We are able to decouple the generation from the web application and also pre-generate documents in some cases. Still, the frequency with which content changes requires a faster solution.
So, does anyone have experience of a PDF generation component that can output a content heavy 40 page document in seconds rather than minutes? Or are our expectations unrealistic?
NB: I'd rather not "out" the poorly performing components here as we are seeking support from vendors to make improvements. I've reviewed previously questions posted on StackOverflow and none appear to deal with this type or size of document.

View 6 RepliesUsing data posted by a mobile app to my database (via a web api) I will need to create PDF forms with the data filled in as if a user did that. I never did PDF generation, so some "points" that might decide what to use:

-Some pages are in portrait, while others in landscape.
-Some columns have the data printed vertically.
-I will need to put images (saved in database, byte arrays) in some fields.
From what I read so far ITextSharp seems to be a popular choice?
I have to open pdf documents from my website. I was thinking of just doing a simple <a href...> to the pdf document. I noticed that in other places on our websites the programmers always do it in the code-behind using the following code : With Response

.WriteFile(directory and document location)
.End()
End With.
