Membership Generate Password Alphanumeric Only Password?

Apr 12, 2010

How can I use Membership.GeneratePassword to return a password that ONLY contains alpha or numeric characters? The default method will only guarantee a minimum and not a maximum number of non alphanumeric passwords.

Security :: Why Password Length Minimum: 7. Non-alphanumeric Characters Required: 1 - NOT PASSWORD RELATED

Feb 24, 2011

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.

Generate Membership Password Hash In Pure TSQL

Feb 17, 2011

I'm attempting to create a pure t-sql representation of the default SHA-1 password hashing in the ASP.Net Membership system. Ideally, what I would get would be this:

UserName Password GeneratedPassword
cbehrens 34098kw4D+FKJ== 34098kw4D+FKJ==

Note: that's bogus base-64 text there. I've got base64_encode and decode functions that round-trip correctly. Here's my attempt, which doesn't work: SELECT UserName, Password, dbo.base64_encode(HASHBYTES('SHA1', dbo.base64_decode(PasswordSalt) + 'test')) As TestPassword FROM aspnet_Users U JOIN aspnet_membership M ON U.UserID = M.UserID

I've tried a number of variations on the theme, to no avail. I need to do this in pure T-Sql; involving a console app or something like that will double the work. So if anyone can supply what precisely the syntax should be to duplicate that password from the ASP.Net membership stuff

Security :: Migrating Existing Cleat Text Users Password To Hashed Password Membership Provider?

Sep 9, 2010

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 .

Does The Password Have Alphanumeric Character

Apr 12, 2010

My ChangePassword method returns a boolean value indicating whether the change of password has been successful or not. When the user enters a new password, I want to check if the password length is at least 8 and there is at least one non-alphanumeric character(both these parameters specified in the web.config file). If I want to check in my code if the password entered is at least 8 characters, I would write some code like this:

if(newpassword.Length !=8)
{
//do something
}

Like the Length property, is there some property that can check if the password contains at least one non-alphanumeric character?

Old Password Still Working After Password Change In Membership?

Sep 21, 2010

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.

Web Forms :: Reset Password" Form, The First Text Box Set With TextMode Set To "Password" Is Populated With The Users Saved Password?

Mar 11, 2011

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?

Add Password Requirements To Membership Provider?

Sep 8, 2010

Do I need to make a Custom Membership Provider or is there another way?

I have a project using ASP.NET Forms Authentication and the Microsoft SQL Membership Provider. The website is DONE. I use this provider everywhere. (Register, Login, Forgot Password, etc...) Until now, my website users have not needed complex passwords. The users' passwords were really just pins. The user could select anything for a password in the past. I had almost no restrictions for this website because none of the data is private or personal. However I have received new requirements.

Here are the new password requirements:

Passwords must be at least 8 characters in length. Passwords must be created using 3 of the following 4 character types:

Uppercase
Lowercase
Numeric
Punctuation

Do not use your name or User ID in the password. Do not use old passwords again later. Passwords must be changed at least every 60 days. Passwords may not contain your User ID or any part of your full name. Password history retention will prohibit use of the last 24 passwords. Passwords may be changed by users only once in any 6-day period.

I realize I am going to have to modify all of the following pages: Register, Login, Forgot Password, etc... fortunately I stopped using the default controls a long time ago.

My first thought was that I need to write a Custom Membership Provider. I don't know how to make the standard provider to do most of this. I could write code to do.

Do I modify the aspnet_membership table? Should I add my own table aspnet_something? Can the user profile table be used for this problem? Do I need my own MembershipUser class?
