I have a web form, which is to allow user to reset their password. When I clicked on the button, I got this error
"Input string was not in a correct format."
The code behind the button is:
[Code]....
When the user types in the new password, this new password will be hashed upon clicking the button and saved into the database.
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 .
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?

The customer complained about saving the password in clear text format. Is there a way to save the password here as hashed?
i m searching a way to compare the password in hash formatting. the saved password in database is in hash formatting and trying to change password. the changed password should be save in hash formatting as well. plz tell me the solution.protected

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?

I'm using a website as a frontend and all users are authenticated with the standard ASP.NET Membership-Provider. Passwords are saved "hashed" within a SQL-Database.Now I want to write a desktop-client with administrative functions. Among other things there should be a method to reset a users password. I can access the database with the saved membership-data, but how can I manually create the password-salt and -hash? Using the System.Web.Membership Namespace seems to be inappropriate so I need to know how to create the salt and hash of the new password manually.

View 4 RepliesI have an asp.net website that requires users to login using their Active Directory credentials. All users of the website have AD accounts. Some of the users are at remote locations and share a common computer login (I know this is not recommended but it is what it is, I have no say in that). Every so often a user will log into my website and click the Remember Passwod box which causes the next person that comes along to not be prompted to log in. All users are on IE 7. I have tried having them go into tools and deleting the cookies, saved passwords, etc but when they go to my website they are still not being prompted to log in. I have recently migrated to IIS 7 and I understand there is a way to have the user enter the site through a custom form but I have not gotten that far yet. How can I make sure the users password is removed from IE?
View 3 RepliesI 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) {

aspx code:-
<tr>
<td class="auto-style1">Old Password</td>
<td class="auto-style2">

<asp:RequiredFieldValidator ID="reqtxtOldPassword" ControlToValidate="txtOldPassword" runat="server" ErrorMessage="*"></asp:RequiredFieldValidator>

View 2 RepliesI have a form that is used to add and edit data. Based on a dropdown selection, the form is either prepopulated or left blank so you can add new data.
I have a password field that is set to TextMode="Password" and works fine when adding new data, it displays ***** as you type..
Now if you select from the dropdown and there is already a record on file, it populates the form to allow you to edit the information.. Now i DONT want to display the password in plain text, but i want to populate the field so if they make any changes all field data is kept and table is updated with all of it.
I already debugged the page and my variable is being set with the password, but the textbox doesnt even show the ***** for the password value.
