C# - How To Show Password In Asterik Format When Generate Random Password
Sep 17, 2010
i am generate random password and show it in a textbox. when i am set textbox property textmode to password then it doesn't show in textbox but when i set it singleline then password shows in textbox. I am using following code --
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.
I want to create a random password generator in my ASP.NET C# web application.
I have created that but it is applicable only for the integer format. If I give any characters it shows the debugging error as "my input format is wrong".
But i want to enter both string and integer. For example my textbox field may be
I have a system where I salt and hash passwords before saving them to the database, using FormsAuthentication in asp.net
What I want to do is, rather than ask the customer for their password each time, I just want 3 random letters from their password. How can I compare this to the hash in the database? Will hashing still work in this case? From what I gather hashing is only designed to be a one way process and shouldn't be decrypted, so is checking 3 random letters for a hash even possible?
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?
how can we attached secure PDF to mail in asp.net ...(Means when we attache any pdf to mail after getting mail at d opening of pdf it should ask password..)
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 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.
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:
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
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)?
URL...how we can sending formatted email now in my Login.aspx page i have Textbox that when users forget their password they should type their Username on the textbox and after that click on send button.I want when users click on send button their user name that they type in textbox be on the email that send to me .
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:
I have written a javascript code for handling the password functionality. The scenario is: when user wants to change the old password, he cannot fill the same old password again. I have written the code. But even the simple alert of blank textbox is not working. See the code for reference:
Javascript code:-
<script type="text/javascript"> function ltrim(str) { var reg reg = /^s+/g return str.replace(reg, "") } function rtrim(str) {
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?
