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 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 .
I have an ASP.NET application that requires impersonation as an administrator user. In web.config:
<identity impersonate="true" userName="administrator" password="password"/>
The customer complained about saving the password in clear text format. Is there a way to save the password here as hashed?
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 have implemented asp. net membership authentication and one of my users has forgotten his password.
The passwords are hashed and when i try retrieveing his password i get the error that password retrieval is not available for hashed passwords.
Should i reset the password?
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'm finding surprisingly little information on converting an existing database from Encrypted passwords to Hashed passwords. (I was able to find a bit more information on converting the other way, but it wasn't of much help.)
As most people know, changing the passwordFormat setting in web.config only affects new users. I have a database with a couple of hundred users and I'd like to convert them to use hashed passwords without changing those existing passwords.
I 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.
I setup a website to use hashed passwords with the membership provided by Asp.net. I'm looking for a way to convert all passwords to clear text. Hashed passwords are overkill for this site and many users can't figure out how to cut and paste the complex temporary password when they request a forgotten password. I understand that you can't retrieve a hashed password.

I have a problem .I am using CAPICOM for digitally sign the data and for this purpose i am using SHA1 algorithm.In CPICOM there is one class CAPICOM.SignedData which is used for this purpose.My problem is how can i give SHA1's hashed data to this class (to it's sign method) for returning the digital signature of exactly 172 bit long?

I've taken over a website which has around 3000 users registered using the standard asp.net membership provider on a SQL database. When the website was set up there were a lot of gaps in the system and we have a lot of tidying up to do of users with the same email addresses etc and invalid addresses so i'm just starting to look at how i can wrap all of this up and make administering the user accounts easier.
At the moment the account passwords are stored in "Hashed" format set in the web.config and obviously this doesn't allow for password retrieval. I want to know whether there is a way of converting all of these passwords from a hashed format to an encrypted format thus allowing me to create a password recovery page that doesn't then send the user a new password which is quite often something like "a*ns7#<3lx"
Ideally i'd like to convert all of these if that is possible so that I do a much simpler password retrieval system. If this is not possible can you tell me how i go about setting the passwordreset value not to contain all sorts of non-alpha/numberic characters?
So as the title suggested, I'm currently trying to compare the hashed answer in my database against the answer typed in the textfield by the user in the form.
I thought of hashing the answer in the textfield typed by the user first, and after that compare this newly hashed answer to the one in the database (which is already hashed). But when I typed in the SAME answer (before hashing) and hashed it to get the hashed value, by right the 2 hashes (in web form and database) should match? Somehow, it didn't. And I can't seem to get security answer right anymore (even though I typed the SAME security answer).
This is the code behind the button:

I tried in another way too, but still the same thing.

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?

View 3 RepliesQuestion: Anybody has experience with ZedGraph / MS-Chart controls ?
I am thinking about which to use ?
Basically, I have a tendency to ZedGraph, because I need .NET framework 2.0 while MS-Chart is 3.5 (and I don't know how well a 3.5 assembly works on 2.0) and because I could use it privately, too (I use Linux privately).
But I don't know if MS-Charts offers more. Does ZedGraph for example offer reasonable quality 3d piecharts ?
And reasonable color design, like gradient colors ? And if it does, is it as simple (or nearly as simple) as MS-Chart controls ? And does ZedGraph offer databinding, e.g. a datatable from a database ?

I hate webform that no matter what action is done with a client side page(such as clicking a dropdownlist to only see the Items), it cause a postback&re-rendering of the whole page and all of the page events is raised( page_init,page_load....complete....).
We know that the server side .cs page shoudnt have to go through all the events and many methods(such as "IsPostback",viewstate), in fact,it just have to do only one thing:get data from DB for the dropdownlist and show it to us, other part of the page just doesnt have to change.
We may achieve this effect using Ajax, but the key is I dont wanna raise too many useless event .
seems MVC can handle such a problem, one action of browser side is replied by exactly one method,and time isnot waste by raise event...
Is this the biggest advantage of MVC?
I am looking for an open source CMS for ASP.NET MVC. I have found MvcCms, N2, and AtomicCMS. I'm looking for any advice, anecdotes, resources or articles comparing the different open source projects so I can find the best one for my project. I'd like to find information about the features, extensibility, relative reliability and continued development of the different projects.

I have two data tables, Results1 and Results2. Results1 are used to hold records that matches with the user selection criteria. Results2 holds records that matches with the user selection criteria with one search criteria omitted.
The two tables have identical fields. I need to get all the records that match Field 2, Filed 3 and Field 4 in both of the tables.
Can compare one record at a time with all the ohers but would like to find a more computationally easier method to do this....
what MVC stands for,but if I'm already developing .NET websites without it,is there any reason I would need/want to use it?is it designed for people who already have experience with developing in an MVC environment and wanted a ".net"version of it?Is there some "head-to-head" comparison of MVC against other programming environments or techniques that have been written? It seems like what I might gain in development speed I might lose in flexibility.maybe I just don't understand what all the fuss is about.hence this post!

Is there a function similar to CopyWebsite that would allow me to compare the files between my laptop and the hosted webserver? Tonight I deleted all the files off of my computer and downloaded the complete website from the hosted server just to ensure that I had the most recent copy. It would have been nice to have run a comparison routine to see if the files were identical. I have using Visual Studio 2010 Pro
