I want to encrypt the querystring and then decrpyt. Is there any way to do this in C#?
Encrypt request.querystring and Descrpt request.querystring
View 1 RepliesI was wondering how you could encrypt/decrypt your querystring in a simple asp.net page? some values need to be passed between different pages but the querystring cannot be changed or read.
Some say httphandles could be the solution for this.
MORE BACKGROUND INFO:
this is the problem, sometimes the sessions disappear without any reason (well there must be one but I don't know it yet). I've looked into the possible reasons but nothing that could cause it is happening.
Therefore I cannot rely on it anymore. The cookie solution is a possibility but it will be more work to implement than simply using the querystring. The url can be copied at any time just not changed!

View 1 RepliesHow can i use querystring for this-
Here in below code i have used querystring for sending imagename from this page to another page. Now i just want that with this imagename in also want to send span element's text with same querystring.How can i achieve this?
[Code]....
The following code works well as long as I pass a querystring value to the datalist.
Private Sub BindGrid()
Dim id As Integer = Integer.Parse(Context.Request.QueryString("id"))
Dim strConnString As String = ConfigurationManager.ConnectionStrings("Conn").ConnectionString
Using con As New SqlConnection(strConnString)
Using cmd As New SqlCommand()
cmd.CommandText = "select Id, Name from tblFiles where Id=@Id"
[Code] ......
However, the page errors with the message "Value cannot be null." if I don't pass a value. I know that DataList does not have an EmptyItem Property like a Gridview control. I do not want the page to error if I don't pass a value. Need info to deal with empty values in a datalist.
Most websites have pointed me to this code to use:
<FooterTemplate>
<asp:Label ID="lblEmpty" Text="No Result" runat="server"
Visible='<%#boolean.parse(([b]list[/b].Items.Count=0).ToString())%>'>
</asp:Label>
</FooterTemplate>
The 'list' throws an error. The error is "Too few type arguments to 'System.COllections.Generic.List". I am not sure if the code is written in C# and that is what is causing the error. It seems that it should work but I can not figure out the 'list' error.
I'm intermittently seeing this exception being thrown:
A potentially dangerous Request.QueryString value detected
However when I look in the IIS logs I can see that the request that failed has no querystring logged against it.
How could this be? Are "dangerous" query strings being stripped from the log or something?
We are creating a Silverlight application and need to have a few parameters pass in with the url from calling site.
example: http://oursite.com/index.aspx?test=d53ae99b-06a0-4ba7-81ed-4556adc532b2
We want to give the calling website 'test' string that links back to the guid of our table which tells the Silverlight application what it's task is when they arrive. We also use this guid for authentication on our application among other things.
The guids are as such:
d53ae99b-06a0-4ba7-81ed-4556adc532b2
8354b838-99b3-4b4c-bb07-7cf68620072e
Encrypted, the values are much longer:

WVMN7B0FPa18/Q7+U4njb5AOKnx6Ga9xoAsvCET6MyjM5TV6dO86OexaCXDiXaES
My question is, with security in mind, should we give them the guid encrypted or like it is unencrypted?
What is everyone's experience with this type of parameter passing?

View 2 RepliesI would like to encrypt cookies in ASP.NET.
I have followed the method in this article, but it has the drawback that is uses reflection on an internal method. This has caused it to be flagged in a code review -- it is not future-proof as the internal implementation may change.
Is there a method with identical functionality which doesn't require using encryption on internal methods?

I'm very new to asp and vb.net, I've just learned about regular expression validation but one thing is bugging me: How can I hide my expression from being viewed on my source code?
The plan is to make a very simple 'login' type of page. I know this goes against all that is holy in this kind of operations, but it's just something I'd like to try out.
Also, after the expression has been validated, I want to load another page, I was thinking of achieving this with:
<asp:TextBox ID="txtcp" runat="server"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ErrorMessage="CP Errada"
Display="Dynamic" ControlToValidate="txtcp" ValidationExpression="admin"></asp:RegularExpressionValidator>
and in vb:
If txtcp is validated then Response.Redirect("mypage.aspx") end if
But the syntax on this IF is obviously not right
