This module is a simple windows application that generates machine keys for web farm
Introduction
The <machineKey> Element configures keys to use for encryption and decryption of forms authentication cookie data and viewstate data, and for verification of out-of-process session state identification. This section can be declared at the machine, site, and application levels, but not at the subdirectory level. Using this pattern allows your application to save your authentication ticket, in away that you can travel around different websites that have the same machine key using this ticket.

Machine Key
Machine key comes in the following format:
Asp.net 4.5
- I have an ASP.net 4.5 application that is running with an auto-generated machine key. I need to spin up another server and I want to set it's machine key to be the same as the other, so tokens and logins can persist across both servers.
- Web Farm and - ASP.NET Security. I have a Web Farm and I understand that in order to keep ViewState safe I want to modify the. 1) The doentation indicates that EnableViewStateMac defaults to 'false' but I am seeing View State corruption messages (as a result of HttpException).

Machine key generates a unique key which helps you on single form because it helps to protect your Form Authentication cookies and page level View state
Introduction
Machine key generates a unique key which helps you on single form because it helps to protect your Form Authentication cookies and page level View state. When user sends a request and Server A receives response with form Authentication cookies, now again he sends a request which was received by Server B and attempted to decrypt form authentication cookies which was unsuccessful to decrypt because server A was using his own unique machine key and server B was using its own unique machine key to decrypt the form Authentication cookies. To avoid this problem, use the same machine key on all servers.
