There are few scenarios that you want to add MachineKey into your web application’s web.config:
Jul 21, 2017 Hi, I am using Asp.net membership in my application. We were using SHA256 for validation and 3DES for decryption (Asp.net membership) in machine key in. Sep 26, 2019 However, sites that are running under the application pool identity do not have access to the HKCU registry. This is where the ASP.NET runtime stores its auto-generated keys. The result is that ASP.NET cannot persist the auto-generated key when the application pool is reset. 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. Mar 19, 2019 To enable the machine key works with the form authentication successfully, you may need to keep all the server use the same encryption and decryption key. You may also need to use generate keys button in action panel to generate the key manually, then you need to copy the key to all the server manually. Best Regards, Yuk Ding.
To fix problem #3, you can also set one of all these in the <page settings:
<page enableEventValidation=”false” viewStateEncryptionMode=”Never” enableViewStateMac=”false”
However you have to be aware of the risk of this change, as it opens door for ViewState value tampering. (Joteke has an intersting finding on large pages having gridview control. Basically in this case, you have to set above values for avoid the error, which is casued by the position of a hidden field containing some encrypted information.)
Here are 2 online tools to generate the random machine key for you: this and this. A sample MachineKey node:
<machineKey
validationKey=”56AB7132992003EE87F74AE4D9675D65EED8018D3528C0B8874905B51940DEAF6B85F1D922D19AB8F69781B2326A2F978A064708822FD8C54ED74CADF8592E17″
decryptionKey=”A69D80B92A16DFE1698DFE86D4CED630FA56D7C1661C8D05744449889B88E8DC”
validation=”SHA1″ decryption=”AES”
/>
The <machineKey> should be put inside <system.web> section.
Please refer to MSDN for documentation: syntax and overview.
-->Provides a way to encrypt or hash data (or both) by using the same algorithms and key values that are used for ASP.NET forms authentication and view state.
The MachineKey class provides methods that expose the hashing and encryption logic that ASP.NET provides. For information about which encryption and hashing algorithms ASP.NET uses, and the key values that it uses with them, see machineKey Element (ASP.NET Settings Schema).
Warning
The MachineKey APIs should only be used in an ASP.NET app. Behavior of the MachineKey APIs outside the context of an ASP.NET application is undefined
