I'm using the ChangePassword method of membership provider to change the password and one of the requirement before calling the ChangePassword is to retrieve the current password. But I'm getting error:
padding is invalid and cannot be removed
below is my web.config:
[code]....
I can recover my password but when I try to change my password to something a bit easier to remember it gives me:
Password incorrect or New Password invalid. New Password length minimum: 7. Non-alphanumeric characters required: 1.
I have all application errors sent to my email. I keep getting this:

i googled and read to add machineKey in my web.config <system.web> which i did:
<machineKey validationKey='0EFA95136AEA44850D5CEDDF0CC7502B1A009.....' decryptionKey='E88EB13ADB2C3D395193AA71DBB1E...' validation='SHA1'/>
and added
<pages masterPageFile enableViewStateMac="true" viewStateEncryptionMode="Auto"> to my masterpage.But i keep getting that error.
I am using following code to encrypt and decrypt files. It works fine in windows application but shows an error in asp.net class. It's using Riijandael method.
Error : padding is invalid and cannot be removed

I using change password control, how can i change the password without enter the current password?
View 8 RepliesI'm getting the following error in our QA environment but only through the IIS7 reverse proxy. If I hit the application server directly it works fine. In our DEV environment it works fine through the proxy or directly.
I'm not really sure where to go with this,

This issue is occuring on and off and I am unable to reproduce it at my end.
Recently, a couple of my applications have started throwing exceptions with the message Padding is invalid and cannot be removed intermitently
My applications already have a machineKey specified in the web.config as suggested in this thread
The applications are deployed to a single Windows 2003 server running IIS6.
We (out IT partner really) recently changed some DNS for a web farmed site we have so that the two production server have round-robin DNS switching between the two. Prior to this switch we didn't really have problems with WebResource.axd files. Since the switch, when we hit the live public URL, we get an error:
CryptographicException
Padding is invalid and cannot be removed.
When we hit the specific servers themselves, they load fine. I've researched the issue and it seems since they're sharing assets between two servers, we need to have a consistent machineKey in the web.config for each server so they can encrypt and decrypt consistently between the two. My questions are:
Can I generate a machineKey via a tool on the server, or do I need to write code to do this?
Do I just need to add the machineKey to the web.config on each server or do you think I'll need to do anything else to make the two server work together? (Both web.config's currently do not have a machineKey)
how can we use the change password using control where the effects take place in database

Create a randomGuid/Cryptographically strong random number Send a unique URL containing the random number to the user's email address When confirmed, the user is asked to change password

The security issues with this type of procedure have been discussed here before.
I am developing a shopping cart with asp.net and sqlexpress. I am using aspnet authentication components to create a backend page. I designed the site to let in only authorized users in.
Yesterday, I forget my password to login to backend and asked system recover my password. with recover password of the asp.net I was able to receive the temp password. I took that and logged in, of course asp.net forward me to password change component which I am having problem with.
Every time I change my password , password change shows that I was successfull but after clicking on the continiue button password change component comes back. I went to properties of password change component and entered the main default page as destination but it is not helping.
I close the IE clear the cache , even restart the machine. When I login always taking me to the password change page.
We're getting this InternalSubStringWithChecks exception with our application's healthMonitoring. This exception is like the Padding is invalid and cannot be removed exception where it's being recorded and we're getting a notification email but the end user is unaware that an actual error has happened. Though we don't want our event log filled up with this rubbish! The stack trace is:

Am using ASP.NET membership authentication in a small website and i just noticed some thing funny during testing. Am trying to enable user to change their login password any time they wish, i dragged a change password control to the form, i changed the password for my test account, but now all passwords are still working.
I can login with the old password as well as the new password with this particular test account. If i try with any other random characters as the new password, i cant successfully login (which OK). But if type the old password, am able to login, if i type the new password, am still able to login, am finding this very strange.
I have a problem with changing the password from Microsoft Access Database. I get an Error "No data exists for the row/column". The password in the database is encrypted and when I change the password it should be decrypting the password and new password should be updated with encryption again. I have following Encryption and Decryption Function:
Code:
Imports System.Collections.Generic
Imports System.Linq
Imports System.Web
Imports System.Text

My company has some unique password policies (such as a pwd cannot be re-used for 6 months, aside from the must include #, special character, upper & lower case)Can anyone suggest how to go about ensuring that a new user's password complies with these policies (using forms authentication in .net 3.5 framework)?

View 1 RepliesI want to force the user to change his password after his first login. Now, where should I put the redirection code to ChangePassword page ?
If I put it in the Page_Load of Default page, user can move to any page because he is Authenticated. If I put it in the Page_Load of Master page, the ChangePassword page uses the same master page, and it'll enter in an infinit loop of redirections.
I though of ignoring the redirection if the Page is the ChagePassword page from the Master page, and I found this answer which says:
This sounds like a bad idea to start with. The idea of the master is that it shouldn't care what page is there as this is all common code for each page.
I was wondering how I would go about changing a users password in ASPNETDB? There are some stored procedure I've been playing around with such as dbo.aspnet_Membership_setpassword and resetpassword but I've managed to corrupt the login password for my user as now I cannot login anymore (gives wrong username or password message in my webform login screen).Any ideas how I can successfully change my password from the ASPNETDB / stored procedure ?
View 5 RepliesI want to change password. however, i am not sure because I did not use my side as a membership at all.
However, when the user log in, i saved username as a session.
So is it possible for me to use the session.. check the database.. and change the password from there??? :)
How am I suppose to do that?
In create user wizard control forgot password and change password...
