View 5 RepliesA bit more background info as suggested:I'm finsihing of an Intranet CMS web app where I have to use the products API (ASP.NET based). Because of time constraints and issues with Windows authen' I need another way to ensure staff do not need to re login everytime they visit the site to view personalised content. The way it works is that once a user logs in (username/password), a Session ID storing a new different Security context value is generated that is used to display the personalised content. The API login method called uses the username and password as parameters. The only way I can think of automatically logging in the next time the staff visits the site is by storing the password in a enrypted cookie and checking of its existing when the site is visited and then calling the API login method using the username and decrypted password cookie values.Any other ideas as an alternative welcomed.'m using some code found on the web to encrypt and decrypt a password string. It encrypts fine but when it calls the code below to decrypt the string it throws the error "Length of the data to decrypt is invalid" How can I resolve this?
System.Text.Encoding enc = System.Text.Encoding.ASCII;
byte[] myByteArray = enc.GetBytes(_pword);

I'm trying to encrypt some userData to create my own custom IPrincipal and IIdentity objects using Forms authentication - I've serialized an object representing my logged in user to Json and created my FormsAuthentication ticket like so:
string user_item = GetJsonOfLoggedinUser();/*get JSON representation of my logged in user*/
System.Web.Security.FormsAuthenticationTicket ticket =
new System.Web.Security.FormsAuthenticationTicket(1,
WAM.Utilities.SessionHelper.LoggedInEmployee.F_NAME + " "
+ WAM.Utilities.SessionHelper.LoggedInEmployee.L_NAME,
DateTime.Now, DateTime.Now.AddMinutes(30), false, user_item);
string encrypted_ticket = System.Web.Security.FormsAuthentication.Encrypt(ticket);
HttpCookie auth_cookie =
new HttpCookie(System.Web.Security.FormsAuthentication.FormsCookieName, encrypted_ticket);
Response.Cookies.Add(auth_cookie);
However, the string encrypted_ticket is always null. Is there a limit on the length of the user_item string?

Has I understand is the section should be encrypted, but it never happens.
I'm all set on the server side with the RSA key pair installed. Where I'm hung up is trying to get the job done on the web.config file ... can't seem to get the aspnet_regiis command string right. I am using the command string provided by the web host (DiscountAsp.net). Most (all) of the examples I read use a website on the development machine. I actually registered my project in IIS and tried that but it didn't work. In any case I would rather not have to go to the hassle of registering a project in IIS anyway if I can avoid it.
Details:
My web application project is in a folder on my local machine:
D:Projects<project name>
This is most recent (failed) attempt to use aspnet_regiis:
C:WINDOWSMicrosoft.NETFrameworkv4.0.30319aspnet_regiis.exe -pe "connectionStrings" "D:Projects<project name>"
Is it possible to just do this manually by looking at the NetFrameworkConfigurationKey_xxxxx.xml file and entering the values? Seems like it should be do-able except I'm not sure how to parse the xml file for the correct values.
On a related note, when I add the following code to web.config it "announces" that "The keyContainerName attribute is not allowed". Ditto useMachineContainer

I have looked for ideas on this and read several posts but none of them seems to be because the problem is that web.com (my host) doesnt allow us to update web.config on their server programmatically.
