Hi Ravi Vemula, I have a doubt in the password security + MVC application topic. If we look at the code the password is passing as plain text over the channel. If we want to implement a internet website using MVC, i think this approach of implementation is not satisfactory as hackers can use a [...]

Documentation of code, arrrgh!!! Most of us hate it, but believe me its an important part in SDLC. Especially when it comes to maintenance of legacy code, Documentation is a life savior.

Writing Xml Comments in Visual Studio is not going to be a easy going task (for large projects it’s a nightmare too). So I started using GhostDoc, an extension of Visual Studio, which helps and makes Xml commenting comparatively easier. There are many other extensions available which give the same functionality in writing comments, but in this small JumpStart I would like to show how to get started with GhostDoc.

In this Demo, we see how to call a Wcf Service Method from JQuery. We make POST and GET Request for the same Service.

We have a ASP.Net MVC Webform, it only consists of html Controls. We have a simple Registration form, which takes User Name and User Email. Once We client the Submit Hyperlink, JQuery will make a POST request to the WCF Service, which will add the data to our Users List.

To retrieve the data, we have a simple Html Text Input, in which we fill the User Name. Once we give the input and click Retrieve Link, JQuery makes a GET Request to WCF Service, which searches the List of users and send back the Data to browser. We Display result in the Div tag.

The intended application got some secured products in the Sql DB (here the table is Products). Users can login to the DB and can only retrieve products thorough MVC Application. So User first needs to Register to the application, then he can login to the application to retrieves the secured information of the products.

The main attention of the complete process flow is “Registration”, especially Password field. Storing Password as a string into DB is considered as not a good practice, so first we generate a Password Salt using Cryptography, then we use the original Password String along with Password Salt to hash it into a more secured format using a Hashing algorithm. and finally it is stored in the Users table of Sql DB.

While Authenticating User, we get the Password String from User login, then check the DB for Username, get the User Entity from the DB, fetch the Password Salt associated with the User, Combine the Password string and Password Salt to generate the Password Hash, then finally cross check the generated Hash with that of the DB version. If both matches, Authenticate the user or else notify him as Invalid Login.
