Hi,

Activate TLS 1.2 under IIS 7.5. IIS 7.5 handles TLS 1.2 with Windows 7 and Windows Server 2008 R2. But it can only be activated manually. Before starting we strongly recommend a backup of the keys that are going to be edited in your registry. Jul 06, 2011 Generate Machine Key in IIS7. Let’s see the example on how to generate machine key for web site. Open your IIS Manager from Administrative tool- Internet Information Services Manager. In Connection pane on left side of window, click on the website. Double click on Machine Key icon as shown below.

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.

<machineKey validationKey='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX,IsolateApps' decryptionKey='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX,IsolateApps' decryption='AES' validation='AES'/>

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');

This update was initially available only for active users of Windows 8, through a download of the Windows Store application. And as it was an updated major that introduced several improvements in all Microsoft platforms, including Windows 8 and Windows Phone 8. Keygen license key generator windows 8. This project was a change from the traditional Microsoft update policy. This update initially consisted of regular releases of «Service Packs» every two years or so.

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

Machine key generates a unique key which helps you on single form because it helps to protect your Form Authentication cookies and page level View state

Introduction

Machine key generates a unique key which helps you on single form because it helps to protect your Form Authentication cookies and page level View state. When user sends a request and Server A receives response with form Authentication cookies, now again he sends a request which was received by Server B and attempted to decrypt form authentication cookies which was unsuccessful to decrypt because server A was using his own unique machine key and server B was using its own unique machine key to decrypt the form Authentication cookies. To avoid this problem, use the same machine key on all servers.
