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.
What is the regular expression for accepting password that should accept only 8 characters
Presently iam using this one [a-zA-Z0-9]{8,}$
But it should not accept Special Characters
My Requirement is to Minimum Length of Password Should be 8 Whether it may contain Special Characters, Special Character are not Required Password Should be 8
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.
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?
i need a regular expression validator for password that should not allow some of the special characters like % ' " ; *. give me the expression such that it should allow special characters except the above and a numeric a capital letter and a small letter ...
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 .
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.
still, I do get the error that I have to provide at least one alphanumeric character.I do so and the error is still the same.why? is my regex wrong? I also took out the "confirm password" step. is that ok?
I would like to encrypt the password and store it in DB. And if user forgots the password and request for password i have to send him a dummy password to his mail id how can i implement this if any code available At the time of registration i have to encrypt or salt the password and save it to DB..
Am trying to open a .pps/.ppt file through my vb.net code.....due to secure reasons this file is password protected,
However i will not like the end user to put a password when accessing through my application.
Hence i want to pass a password as a parameter while open such a password protected file.
Here is my code.

Where can i provide password while opening a ppt file...
I have to hide the length of the password being entered during login of my asp.net web application. I know the asp.net textbox server control has the textmode of password but I can't even show the that. Any suggestions on how to hide the user input?
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?
I need to construct a regular expression for the password textbox, Min:8,Max:16 and must include atleast a number(0-9),alphabets upper and lower case. I am unable to limit the length to 16.
I am devloping web application using csharp on visual studio. I am asking for a tutorial or urls that is showing on how to ensure that in a password that is being typed in has special character like! * ^ $ and some Capital letters. So that if someone tries to type a password with including these characters and some capital letters it refuses to accept that passord
I want to force user to type more than 6 characters in password field.we cannot usee range validator because password characters can be mix(i.e.Numeric or alphabates or special characters)
I just finished setting up the environment for an ASP based web app on a Windows Server 2003 machine, IIS 6.0, ASP.NET 4.0., with custom service account.This is not a domain based setup, so I have created mirrored logins on both servers (WEB server and SQL Server 2005). Everything works just fine except the fact that every time I try to browse the main page, a login pop-up window will request login password confirmation. I tried many things so far. Making sure IIS is in NTLM Authentication mode, checking access rights for the local login I created, workarounds I found on MSDN, etc.
This happens only if I change the Directory Security to not allow anonymous access (Authenticated Access - Integrated Windows authentication only). If I keep both, or only anonymous, everything works fine.Is this the intended behavior? Am I doing something wrong here?I already tried everything I found on MSDN regarding these types of errors. If I do not enter a password for three times in a row, the error says "HTTP Error 401.1 - Unauthorized - Access is denied due to invalid credential."
I am assigning a value to .Text of a textbox retrieved from a database in Page_Load() but no characters are shown in the textbox after doing this. The value is indeed there when I try to read from it after the assignment. I would like to present some characters to the user even though they are the "dotted" password characters so they know a password has been entered here. Is it possible to do this?
