Encrypt A Password Typed Into A Textbox Before Using Membership.ValidateUser?
Dec 19, 2010
I have successfully created a SQL Server database that is holding the ASP.NET Membership data for my site. I have also created two textboxes and used them for user authentication after he/she keys in a user name and password. I would now like encrypt the password before comparing to the value stored in the Password field of the SQL Server database. However, I have been unable to do this so far.I have consulted the MSDN page for the embershipProvider.EncryptPassword method but I do not understand how to implement it. I have also tried searching Google for this method but I have only found a couple of examples and I don't understand those either.

I have an application with a custom mebership (I'm still working on it). There is some funcionality in the application for asociating users. This means that (if already associated) one user could switch to some other user with just a click.
My question is:
Can I do a function that would allow me to authenticate one user without sending the password as a parameter?

I know this looks similar to other questions here but I don't think my case is the same as theirs.
I have a website that uses the AspNetSqlMembershipProvider to validate users. I would like to use the same database from a console application. According to several articles on the web I can use the System.Web.Security.Membership class from outside ASP.NET by copying the appropriate sections from web.config to app.config. That is what I did.
My console appliction can get the user with the requested name and I can confirm that the user is approved and is not locked out but ValidateUser returns false for a correct username and password pair.
I have found articles where people have had trouble with migrating code which may be due to a machine key mismatch but have also found a reference saying that machine key is only used if the passwordFormat property equals encrypted whereas I am using hashed.
Is the issue that the two pieces of code - the website and the console app - are in different assemblies and the assembly name or other property is being used during password hashing? In both cases the application name property is set to /.
Should I continue with this approach or just access the database directly and hash the password myself?

I have a webservice project and a web project in the same solution.
The web project implements a membershipprovider.
I want to be able to authenticate user via the webservice project but when i call this method in the webproject:
public static bool AuthUser(string userName, string password)
{
return Membership.ValidateUser(userName, password);
}
I get this inner ex."Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed." Calling the method from the webproject works fine. I understand why I get the ex. but not how to solve it.. UPDATE Well I fixed the issue by deleting the C:UsersJRBAppDataLocalMicrosoftMicrosoft SQL Server DataSQLEXPRESS folder.. However now the method always returns false.. It almost seems like it doesn't use the proper connectionstring.

We have just migrated our application from VS 2008 to VS 2010 and our database from Sql server 2005 to 2008. Everything was working great until i tried to login to the site.
As when i try to log into the site, i am surprisingly always getting "FALSE" from Membership.Validateuser (). I goggled it and now i know i am not the alone victim of this irritating bug. Our live site is going to be down...

Does anyone has a solution (sample code) for the following features:
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
My provider is currently parametrized this way:
[code]....
The security issues with this type of procedure have been discussed here before.

I had been trying to solve this but there is a hidden key i wish someone point me to.
I had a simple membership database with users in first the Membership Provider configured for clear password to retrieve the original password .
Now a new requirement say that the password must be hashed and reset .
I configure the Membership password to hash , and Implemented the Reset Password Module.
My problem is as follow.
If the user is new registered user with the new configuration the password and the security answer is hashed.
also when I go and reset the password it continue to be hashed.
Now I thought that with new configuration if any previous user with clear text configuration , If he use the password Reset module , because my configuration now is hashed , I expected that the new password and security answer will be hashed . what happen is old user continue in clear text even if the configuration is hashed. so If I had new users everything is fine.
old users Membership Provider somehow know they had been stored in clear text and it keep change password and security answer in clear text . If I delete this user and create it , Membership Provider understand that everything will be hashed. I need to know how it know this , I need to migrate users not to delete and recreate users .
Also if there are no solution for that , I wish Microsoft Consider it in future cause it is a real user scenario, that can happen imagine a business system that related to membership user Id , deleting users and recreate them is not a solution .

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 the following requirement:
- During client registration, the password must be client side encrypted with SHA1 algorithm and stored in the DB
I have done that before using javascript on the client side. But it was a non MVC web app. I know I can use js again, but I'm trying to find a better approach.Using https or not is not depending on our development side, so we can not change the requirement.
