You can generate machine key (validation and decryption key) yourself and specify it in web.config. The same key will be used in all cases where encryption is performed e.g. Auth tickets, AF Token. A good introduction link. Add Machine Key to machine.config in Load Balancing environment to multiple versions of.net framework. Ask Question Asked 7 years, 3 months ago. 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? Does the validation and decryption keys have to be the same. Jan 12, 2011 how to generate validationKey and decryption Key for web.config Posted in ASP.NET (C# & VB), C#, VB, WCF by Alok Kumar Pandey on January 12, 2011 This article describes how to create keys to use for encryption, decryption, and validation of Forms authentication cookie data.

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 Web.config.

Now my requirement is to use AES encryption for both. I created Keys from IIS and added in my Web.config.

Using That configuration setting, i updated password of 1 of my user in development environment.

MembershipUser mu = Membership.GetUser('UserName');
mu.ChangePassword(mu.ResetPassword(), 'Password');

After that i ran the application to test my password on development machine using below code & it was returning true:

bool b = Membership.ValidateUser('UserName', 'Password');

But when i published the website on IIS on my local machine, It is returning FALSE.

I am not sure why it is happening as the same keys are used at both places.

Thanks

Rohit

Use the Machine Key feature page to configure hashing and encryption settings used for application services, such as view state, Forms authentication, membership and roles, and anonymous identification. Machine keys are also used to verify out-of-process session state identification.

Note

If you deploy your application in a web farm, make sure that the configuration files on each server in the web farm have the same value for the validation key and decryption keys, which are used for hashing and decryption respectively. Otherwise, you cannot guarantee which server handles successive requests.

UI Elements for Machine Key

The following tables describe the UI elements that are available on the feature page and in the Actions pane.

Feature Page Elements

Element Name	/the-sims-3-pets-key-generator.html. Description
Validation method	Select one of the following options to specify the validation method the machine key uses: AES - Advanced Encryption Standard (AES) is relatively easy to implement and requires little memory. AES has a key size of 128, 192, or 256 bits. This method uses the same private key to encrypt and decrypt data, whereas a public-key method must use a pair of keys. MD5 - Message Digest 5 (MD5) is used for digital signing of applications, for example, mail messages. This method produces a 128-bit message digest, which is a compressed form of the original data. MD5 can provide some protection against computer viruses and programs that mimic harmless applications but are destructive. SHA1 – This method is the default setting. SHA1 is considered to be more secure than MD5 because it produces a 160-bit message digest. Use SHA1 encryption whenever possible. TripleDES - Triple Data Encryption Standard (TripleDES) is a minor variation of Data Encryption Standard (DES). It is three times slower than regular DES but can be more secure because it has a key size of 192 bits. If performance is not your primary consideration, consider using TripleDES. HMACSHA256 - Hash-based Message Authentication Code (HMAC) mixes a secret key with the message data, hashes the result with the hash function, mixes that hash value with the secret key again, and then applies the hash function a second time. The output hash is 256 bits in length. HMACSHA384 - Hash-based Message Authentication Code (HMAC) with an output has that is 384 bits long. HMACSHA512 - Hash-based Message Authentication Code (HMAC) with an output has that is 512 bits long.
Encryption method	Select one of the following options to specify the encryption method the machine key uses: Auto – This method is the default setting. Auto works with whichever encryption method you specified. AES - Advanced Encryption Standard (AES) is relatively easy to implement and requires little memory. AES has a key size of 128, 192, or 256 bits. This method uses the same private key to encrypt and decrypt data, whereas a public-key method must use a pair of keys. TripleDES - Triple Data Encryption Standard (TripleDES) is a minor variation of DES. It is three times slower than regular DES but can be more secure because it has a key size of 192 bits. If performance is not your primary consideration, consider using TripleDES. DES - Data Encryption Standard (DES) uses a 56-bit key to both encrypt and decrypt data. If your server, site, or application does not require the strongest security, consider using DES.
Validation key	Computes a Message Authentication Code (MAC) to confirm the integrity of the data. This key is appended to either the Forms authentication cookie or the view state for a specific page. Select one of the following options to specify how the validation key is generated: Automatically generate at runtime: Instructs ASP.NET to generate a random key at runtime. Generate a unique key for each application: Isolates applications from one another by generating a unique key for each application based on the application ID of each application. If your application is deployed in a web farm, duplicate your application's key across all servers in the farm.
Decryption key	Used to encrypt and decrypt Forms authentication tickets and view state. Select one of the following options to specify how the decryption key is generated: Automatically generate at runtime: Instructs ASP.NET to generate a random key at runtime. Generate a unique key for each application: Isolates applications from one another by generating a unique key for each application based on the application ID of each application. If your application is deployed in a web farm, duplicate your application's key across all servers in the farm.
