RijndaelManaged returns empty result

How to do client-side validation of password change in Active Directory

QUESTION

RijndaelManaged returns empty result

Asked 2020-Aug-14 at 09:15

The Problem
I want to decrypt encrypted data with RijndaelManaged but the result is always empty (either "" or an byte array with the length of the data full of zeros).

All parameters, salt and data are all correct, CryptoHelper.CreateRijndaelManagedAES gets called the exact same way in the encrypt method (which produces an good output).

The only thing left I could think of is that I use the streams wrong, but I can't figure out why ...

The issue is in the EncryptDataAsync method, i.e. the encryption (in DecryptDataAsync, i.e. the decryption, the bug only becomes evident). This is because the StreamWriter must first be flushed before memoryStream.ToArray() is called. This call must be executed before:

QUESTION

How to do client-side validation of password change in Active Directory

Asked 2019-Mar-20 at 13:07

My objective is simple: pre-validate a new password client-side (Javascript) as an initial check the password matches the domain/ou password policy, to avoid wasting server resources rejecting bad passwords and give faster responses to users.

The question: How can I get user password policy from Active Directory?

I especially need to know the password "format", password length, capital and special characters requirements, etc. The final validation will, of course, be Active Directory itself. But first I want to use Javascript as a performance optimization, and I'm pretty sure I can manage the Javascript if I can just retrieve the password format requirements for a specific user/OU on the C#/ASP.Net end.

Currently, I'm stuck trying to find WHAT the current password policy is for the user. Yes, user Alice might use the password domain policy, but Bob could have a different password policy in his OU.

This website will be installed in an institution with thousands of users; we want to minimize the back and forth validation against Active Directory. Additionally, having this in Javascript can eventually help in compliance with NIST Special Publication 800-63, which among other things asks for prompt feedback to users on relative password strength. For now, I must be able to make the code work on Windows 2008, 2008 R2 and 2012.

I'm currently able to change the password in C#, and I can get the error, but it's it's all or nothing, and not helpful for client-side validation.

Finding out this information at the domain level is easy. Figuring out if any Group Policies have overridden the default is hard.

At the domain level, there are attributes at the domain itself that govern the default password policy for the domain. You can bind to the domain itself (i.e. LDAP://domain.com) and read these attributes:

minPwdLength: The minimum character length
pwdHistoryLength: The number of old passwords that can't be reused.
pwdProperties: This is a bit flag that could mean various things, which you can read about under the "PasswordProperties" section here. It's likely to be set to 1 (DOMAIN_PASSWORD_COMPLEX), which means a password must include at least two of either uppercase, lowercase and numbers.

If you want to go through the effort to read group policies that would apply to the user's OU, there doesn't seem to be any .NET libraries to do that. You have to resort to using unmanaged code. There is an example here that uses the IGPMDomain interface from C#, but you will have to adapt it to find the GPO for the right OU.
