MachineKey is used for:
MachineKey 用于：
- ViewState encryption and validation
- Forms Authentication (or Federated Authentication) uses this key for signing the authentication ticket
- ViewState 加密和验证
- 表单身份验证（或联合身份验证）使用此密钥对身份验证票进行签名
Having a Web App installed on multiple servers requires same Machine Key configured on all of them in order for Load Balancing to work.
在多个服务器上安装 Web 应用程序需要在所有服务器上配置相同的机器密钥，以便负载平衡工作。

Machine key is also used to encrypt/decrypt the webresources.axd parameters.
机器密钥还用于加密/解密 webresources.axd 参数。
Even on a single server the machine key should be configured, because any recycle of the app domain will generate a new key when it is set to auto. This causes the next postback just for pages rendered before the recycle, to cause a viewstate validation error, and also issues with the resources during that time.
即使在单个服务器上，也应该配置机器密钥，因为当应用域设置为自动时，任何应用程序域的回收都会生成一个新密钥。这会导致仅针对在回收之前呈现的页面进行下一次回发，从而导致视图状态验证错误，并且在此期间还会出现资源问题。
