AES Encryption (Machine Key) not validating user on IIS

' Symmetric encryption algorithms are such that the encryptor and decryptor ' share a pre-known secret key. This could be a 'single-use' key that is ' derived from a secure key exchange algorithm using RSA, ECC, or Diffie-Hellman, ' or it could be a password known to both sides, or ' it could simply be the binary bytes of the secret key known in advance on both ' sides. A 1024-bit key will usually be ready instantly, while a 4096-bit key may take up to several minutes. For a faster and more secure method, see Do It Yourself below. CryptoTools.net does not yet have a tool for facilitating the encryption and decryption of data using RSA, but you may Do It Yourself with the instructions below. Dec 04, 2006 The main one is written in asp.net 1.1 and the second one I want to call from the first one is written in asp.net 2.0. I have defined a static key in both apps (same key!) and made them persistent. In the asp.net 2.0 app I added the attribute decryption=3DES so that it can decode the ticket written by the asp.net 1.1 (the main application). Hashing, Encryption and Random in ASP.NET Core. This post look at hashing, encryption and random string generation in ASP.NET Core. We examine a few different approaches and explain why some common techniques should be avoided in modern applications. Generating a random string. It is a very common requirement to generate random strings.

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');

.net Encryption Library

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. Mortal kombat x key generator download.
