Jan 04, 2017 Generate MachineKey using Windows PowerShell. In this post we will see how we can Generate MachineKey using Windows PowerShell from our local development machine. ASP.NET machineKey Generator. This is an application that will generate a valid machineKey block with random, secure, hard-coded keys that you can paste inside the in your web.config or machine.config file. Hard-coded encryption and validation keys are needed if you have a web farm/web garden, if you use passwordFormat=Encrypted. ASP.net 4.5 copy the current auto-generated MachineKey to another server. Ask Question. 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.

- 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. MachineKey Class (System.Web.Security) Microsoft Docs.
- May 13, 2009 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.
- Uncheck 'Automatically generate at runtime' for both the validation key and the decryption key. Click 'Generate Keys' under 'Actions' on the right side of the panel. Click 'Apply'. Setting Up the Machine Key Directly in the Web.config File. If you do not have access to the IIS management console, it is still possible to set-up a machine key for.
The implementation of the <machineKey> 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.
Package installation
Note
The new data protection system can only be installed into an existing ASP.NET application targeting .NET 4.5.1 or later. Installation will fail if the application targets .NET 4.5 or lower.
To install the new data protection system into an existing ASP.NET 4.5.1+ project, install the package Microsoft.AspNetCore.DataProtection.SystemWeb. This will instantiate the data protection system using the default configuration settings.
When you install the package, it inserts a line into Web.config that tells ASP.NET to use it for most cryptographic operations, including forms authentication, view state, and calls to MachineKey.Protect. The line that's inserted reads as follows.
Tip
You can tell if the new data protection system is active by inspecting fields like __VIEWSTATE, which should begin with 'CfDJ8' as in the example below. 'CfDJ8' is the base64 representation of the magic '09 F0 C9 F0' header that identifies a payload protected by the data protection system.
Package configuration
The data protection system is instantiated with a default zero-setup configuration. However, since by default keys are persisted to the local file system, this won't work for applications which are deployed in a farm. To resolve this, you can provide configuration by creating a type which subclasses DataProtectionStartup and overrides its ConfigureServices method.
Public and private key generation online. Below is an example of a custom data protection startup type which configured both where keys are persisted and how they're encrypted at rest. It also overrides the default app isolation policy by providing its own application name.
Tip
You can also use <machineKey applicationName='my-app' .. /> in place of an explicit call to SetApplicationName. This is a convenience mechanism to avoid forcing the developer to create a DataProtectionStartup-derived type if all they wanted to configure was setting the application name.
To enable this custom configuration, go back to Web.config and look for the <appSettings> element that the package install added to the config file. It will look like the following markup:
Fill in the blank value with the assembly-qualified name of the DataProtectionStartup-derived type you just created. If the name of the application is DataProtectionDemo, this would look like the below.
The newly-configured data protection system is now ready for use inside the application.

-->Definition
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.
Remarks
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
Asp Baton
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
Methods
| Decode(String, MachineKeyProtection) | Decodes and/or validates data that has been encrypted or provided with a hash-based message authentication code (HMAC). |
| Encode(Byte[], MachineKeyProtection) | Encrypts data and/or appends a hash-based message authentication code (HMAC). |
| Protect(Byte[], String[]) | Protects the specified data by encrypting or signing it. |
| Unprotect(Byte[], String[]) | Unprotects the specified data, which was protected by the Protect(Byte[], String[]) method. |
