Demonstrates how to decode an .ASPXAUTH cookie as generated by the current version of Microsoft's implementation of .NET. You should be able to drop this into the `Global.asax.cs` file of an ASP.NET project and be able to share cookies with code running on Mono. A few notes: (1) This assumes a machine key section that uses SHA1 validation and AE…
public void FormsAuthentication_OnAuthenticate(object sender, FormsAuthenticationEventArgs args)
{
var machineKeySection = (MachineKeySection) WebConfigurationManager.GetWebApplicationSection("system.web/machineKey");
var cookie = args.Context.Request.Cookies[".ASPXAUTH"];
if (cookie == null || !Regex.IsMatch(cookie.Value, "^([a-fA-F0-9]{2})+$"))
return;
var cookieBytes = ByteUtility.ToBytes(cookie.Value);
int signatureLength;

Gulp + Sass + LiveReload

This Gist goes over setting up a gulp workflow that will:

  1. watch for any sass changes, then compiles sass source into css
  2. watch for any changes in the public directory, and trigger live-reload
  3. serve static content in public/

Decrypt a Legacy ASP.NET Forms Authentication Cookie (that uses SHA1 validation, and AES encryption) - without horrendous dependencies on system.web.. This allows you to decrypt a forms authentication cookie that was created in ASP.NET 3.5, from an ASP.NET 5 application.
internal static class FormsAuthenticationTicketHelper
{
private const byte CURRENT_TICKET_SERIALIZED_VERSION = 0x01;
private const int MAX_TICKET_LENGTH = 4096;
// Resurrects a FormsAuthenticationTicket from its serialized blob representation.
// The input blob must be unsigned and unencrypted. This function returns null if
// the serialized ticket format is invalid. The caller must also verify that the
// ticket is still valid, as this method doesn't check expiration.

Creating Neat .NET Core Command Line Apps

You can now read this on my (pretty) website! Check it out here.

Every reason to get more HackerPoints™ is a good one, so today we're going to write a neat command line app in .NET Core! The Common library has a really cool package Microsoft.Extensions.CommandlineUtils to help us parse command line arguments and structure our app, but sadly it's undocumented.

No more! In this guide, we'll explore the package and write a really neat
