AES Encryption (Machine Key) not validating user on IIS
Jul 14, 2017 12:05 PM|Rohit Rao|LINK
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.
<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');
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.
