If you want to encrypt integer values, then you're going to need to store the result as a string. If you're also going to roundtrip those values from the server to the browser, you'll need this code.
There’s a potential security exploit that ASP.NET MVC leaves you open to. However, in Peter’s opinion, all the proposed solutions miss the point.
Encrypting data that you want stored in your View and returned to you when the user clicks the Submit button has its own special problems. Here’s a complete solution and, as a bonus, an Encryption object you can use anywhere.
Regular expressions give Tim Patrick the creeps, but he overcame his fears by discovering specially crafted regex patterns can access data in a way that’s actually kind of cool.
Peter completes his walk-through of creating a simple Angular app with TypeScript by responding to events, accepting data from the user and updating data back at the server with an AJAX call.
Your users will make mistakes ... but it would be a mistake to treat all their errors the same way. You can get more out of ASP.NET MVC's validation infrastructure just by paying attention to how you name your errors.
With JSON now the default format for moving data between clients and servers, SQL Server adds JSON support to make it easier to get your data out of the database and down to the client.
If you've ever worked in an enterprise environment and fielded calls from employees unable to get into their accounts due to a depressed Caps Lock key, you know how essential the following tweak to your code can be.
