I want to use PKI public and private encryption for authentication to allow for a more streamlined and secure application access control system. generation of certificate and authentication will be useful. One more question, can i use System.Security.Cryptography.X509Certificates class for the same?

I have an web application that encrypts data using a public and sent it to another web application. Which will then decrypt the data using a the user private key. My question is, since but the Private and Public key are generated in the first application. how does the other application get the private?
View 2 RepliesNames of the private properties of a public class?
I have the following class
[Code]....
I have searched high and low (and very possibly could have missed it), but in my years of programming, I have always come across one practice that seemed to be the standard in OOP, which is to use private properties in an object with public methods to manipulate the data.
However, the more I delve into ASP.NET (specifically with MVC), the more public properties I see inside of classes (specifically models) such as the ones shown at Scottgu's blog discussing the Entity Framework.
Does it have something to do with the way that LINQ populates a class?
I have like 10 private members in my class, and I was hoping vs.net could create public properties from them but can't seem to find that option in VS.NET 2008.
Is there a feature for this?
My site is 100% private (only public facing page is login) I've had the need to open up a page to anon via the <location> node in the web config...and that all seems to work However the issue now appears to be that dynamic resources such as the Telerik.Web.UI.WebResource.axd and imagesjavascript changed via handlers dont load. A firebug of the situation shows that for those dynamic elements, it's trying to re-direct to login to get them Is there anyway around this?
View 3 RepliesBe built an MVC application. Some of the pages require being under SSL encryption. Means the whole site need to be broken down to sections (http and https)The immediate solution that comes to my mind is creating two IIS sites (port 80 and 443) and break the application to two sites (public-http and private-https). Since the site is complex, breaking it into two applications will be huge work.What is the easiest way of doing this?Is there any link or article that explains the best practices doing this?

I have some problem about keeping "Generated Public and Private Asymmetric Keys" in web.config.
At first, I generate key from external application, the result keys are in the xml files named "PublicKey.xml" and "PrivateKey.xml".
Key example,
<RSAKeyValue><Modulus>xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx</Modulus><Exponent>AQAB</Exponent><P>3lJSXraj/fffffffffffffffff</P><Q>th/FSSSSSSSSSSSSSSSSSSSSS</Q><DP>FFFFFFFFFFFF</DP><DQ>A0SfrELG91Fz8/LmcqwlZRu7a7ZVldC1fAtsK+6M6aQ3d4dBp5coDP6wz5ah2dFrbinpVZjSjLmLXYSmTK2aYQ==</DQ>

By default web service is enable for windows authentication. But if we want to expose our service to public domain, then I guess we have to use some specific credential for web service authentication. Can anyone tell me how to set those credential at service side and validate it for client and how the client will send those credentials?
View 1 RepliesIn my development environment everything works as I expect. I can access all the pages and as soon as I get to a secured page I check the Request.IsAuthenticated and redirect to the login page if needed. The problems starts when I deploy the project under IIS7. When I access the site I'm being redirected to the login page (as defined in the web.config) although it suppose to be a public page... If I disable the Form Authentication in the admin console Request.IsAuthenticated always return true.So

View 5 RepliesNot sure if I'm posting the question in the right category.
1) I'm working in a project where encryption of data is high priority. Could some one suggest what would be the best encryption method to protect data from being cracked.
I'm using TCP/IP protocol.
2) Is HTTPS totally secured. If I'm using HTTPS, does that mean that there is no encryption of data required in the coding?
When you need to store sensitive data such as CCs or SSNs, do you:1) Build your own encryption routine within the application, define a secret key somewhere in a config file, and then manually encrypt/decrypt data going to the database.2) Push all the problem to the database, using the built in DB capabilities (I think most vendors call it Transparent Database Encryption).What trade-offs have you find for your solution? Does writing your own routine perform poorly when compared to TDE? Is code maintainability, or conversely DB vendor lock-in an issue?

View 3 Repliesif a class has a private constructor then it cant be instantiated. so, if i dont want my class to be instantiated and still use it, then i can make it static. what is the use of a private constructor? Also its used in singleton class, except that, is there any othe use ? (Note : The reason i am excuding the singleton case above is because I dont understand why do we need a singleton at all ? when there is a static class availble.
View 8 RepliesCan it handle mapping using private members like NHibernate can? The documentation is very slim, but it seems like one of the objects or methods provided with the tool could do something like this.
Mapper
.With<FooDTO>()
.Map(x => x.Value)
.To<Foo>("_value");
// To<T>(string member) or To<T>(Func<T, bool> func)
Mapper.CreateMap<Foo, FooDTO>();
I know my example methods don't exist as-is, but maybe I've overlooked something else already built in.

con = new SqlConnection(constr);
da = new SqlDataAdapter(ssql, con);
ds = new DataSet();
da.Fill(ds, "ITEM");
dv = ds.Tables("ITEM").DefaultView;
cbo.DataSource = dv;
}
But here some error message is coming in "private FillCombo function" like "'object' does not contain a definition for 'DataSource' and no extension method 'DataSource' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?)" So, how can i correct this error?
