Generate Machine Key Web.config
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. Jun 11, 2012 The script looks for the key being set in machine.config, so if you have it set in IIS Manager, then it's being set in the root web.config file. Modify the script to use web.config instead of machine.config for the config file path. Add the value to the Web.config: Now that you have the key, you can use some of the wix custom actions to modify the web.config, you can use XmlConfig or XmlFile. With this you will be able to modify the Xml file to add the machineKey node using the property created on the previous step. Apr 15, 2009 MachineKey in web.config There are few scenarios that you want to add MachineKey into your web application’s web.config: You have a web farm and in each server the machine.config set to auto generate machinekey. You want to use “Encyrpted” password format in ASP.NET membership provider. Dec 21, 2009 The IsolateApps modifier causes ASP.NET to generate a unique key for each application on your server by using the application ID of each application. You can override the protection attribute setting for all Web applications on the server by using the machine-level Web.config file or, for a specific application, by using its Web.config file. Add Machine Key to machine.config in Load Balancing environment to multiple versions of.net framework. Ask Question Asked 7 years. How do I add a machine key to the machine.config file? Do I do it at server level in IIS or at website/application level for each site? You can add it to your web site's web.config. If there are multiple.
-->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.
Web Config Configuration Files
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.
Generate Machine Key
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.
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.
Hide my ip 6 key generator. 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.
Machine.config File
The newly-configured data protection system is now ready for use inside the application.
