Generate Machine Key Asp Net 4.0
The machineKey element of the ASP.NET web.config specifies the algorithm and keys that ASP.NET will use for encryption. By default the validationKey and the decryptionKey keys are set to AutoGenerate which means the runtime will generate a random key for use. This works fine for applications that are deployed on a single server. When you use webfarms a client request can land on any one of the servers in the webfarm. Hence you will have to hardcode the validationKey and the decryptionKey on all your servers in the farm with a manually generated key.
There are a lot of articles that describe how to use RNGCryptoServiceProvider to generate a random key. There are also a lot of online tools that generate random keys for you. But I would suggest writing your own script because any one who has access to these keys can do evil things like tamper your forms authentication cookie or viewstate.

I understand the security risks of this, but that was the decision that was made. Replace the ASP.NET machineKey in ASP.NET Core.; 2 minutes to read +2; In this article. The implementation of the element in ASP.NET is replaceable.This allows most calls to ASP.NET cryptographic routines to be routed through a replacement data protection mechanism, including the new data protection system.
