View 1 RepliesI am using asp.net membership and I have checked the table aspnet_membership and I can see two fields password and saltpassword which look like this QoasdDKkh5x9RizpadsGsC9N30= and tO9xYGRkjaFGaskKnTVobiJnMDQ== respectvely.
is there any tool, Stored procedure, program, online utility tool by which I can see the actual text of that password?

I want to encrypt the password entered by the user....how do i go about it?is there any built-in function for it or will i be required to write a code for it?
View 5 RepliesI received some code, a small c# asp.net application which manually posts a shared username/pwd to a 3rd party website for auto-logins from our intranet site. During transit the password is encrypted, but not within the application. Within this application a namevaluecollection is used and the username and password are hard coded. Originally the thought was, who cares if its hard coded because its shared between everyone anyway. Now we want to encrypt the username and password from within the application. I'm not sure the best way to accomplish the goal of making sure the password is encrypted "at rest". Normally I've seen passwords stored and encrypted within a database. I know we'll obviously have to move the password out of the application and store it somewhere else, I'm just not sure where. Do we move the username and pwd to the web.config file? I really am not sure the best way to approach this.
View 1 RepliesI 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.
So, I am the approach David Hayden posted on his blog [URL] to create a salt and hash the user's password by taking the user's raw password and the generated salt and using SHA1 to hash the value. I then store the salt and the hashed password in the database. zhe website is currently load balanced, so I was wondering if resulting hash value would be the same for both servers. Here is the snippet of code posted on David Hayden's blog:
private static string CreateSalt(int size)
{
//Generate a cryptographic random number.
RNGCryptoServiceProvider rng = new RNGCryptoServiceProvider();
byte[] buff = new byte[size];
rng.GetBytes(buff);
// Return a Base64 string representation of the random number.
return Convert.ToBase64String(buff);
}
private static string CreatePasswordHash(string pwd, string salt)
{
string saltAndPwd = String.Concat(pwd, salt);
string hashedPwd =
FormsAuthentication.HashPasswordForStoringInConfigFile(
saltAndPwd, "sha1");
return hashedPwd;
}
The reason I ask is that this code uses the code snippet: FormsAuthentication.HashPasswordForStoringInConfigFile(saltAndPwd, "sha1");
I am using Forms Authentication in a new ASP.NET 3.5 Application.I have created the Tables in my database and run the Web Site Administration Too.When I try to create a user I get a password error no matter what I throw at it and I am becoming sure of that this is a symptom of an a setup error and not a password problem.One of the things that I notice is that my aspnet_Applications is empty and I am not sure what is supposed to fill it.I have tried to delete all the aspnet tables and done the procedure again but with the same result.
View 1 RepliesI using change password control, how can i change the password without enter the current password?
View 8 RepliesI 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 .
I just begin creating a website for an organization. First page to be displayed in the login page. I dont have any knowledge in ASP.NET Security. On Login page, i want to display UserName field as disabled with the useralias of the user who currently logged into Windows. Password user has to provide and it should be that user's windows password.
How do i validate that password that user has entered is his windows password?
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.
Is there a way to assign a value to the password and confirm password fields of the CreateUserWizard control programmatically when the page loads? The CreateUserWizard.Password property is read-only.

When a user that has their IE set to save passwords hits my "Reset Password" form, the first text box set with TextMode set to "Password" is populated with the users saved password. Understandable, this is not the affect I would like as this is their "old" password. I cannot set the text of a text box with mode set to "Password" (naturally). Does someone know how to suppress or clear this value when IE is saving passwords?
