How can I view the user passwords store in asp membership table.
I retrieve all user data on gridview but password is encrypted how to dycrypt password.
I have an asp.net page where I have used FormsAuthentication.HashPasswordForStoringInConfigFile. Encrypted password is saved in database. I have created a forgotPassword page. Where I need to send user his password. How can I decrypt it and send it to user. if SHA1 can not be decryoted what other option should I use to encrypt the passwords?
View 5 RepliesI use MS SQL SERVER DB to store some servers' info with help of ASP.NET application and I want to know the strong way to encrypt and decrypt server's passwords and store them in that DB.
provide me the way in details + code since I didn't deal with encryption before..
is there any way to decrypt the membership password?
View 1 RepliesI am using asp.net website , now when a user creates new account his password must be saved in hashes , or gets encrypted and submits in database , next time when he login , my application fetch password from encrypted field , then decrypt it and match with the user entered password , if that's ok , page will be redirected to some other pages ... how to do that task ??
View 1 RepliesI created a Membership login system for my client, now they do NOT want the user to use one of his 5 last passwords when it comes time to create a new one.
Is that something that is build in or how could I accomplish that?
Is there an utility or code sample that can decrypt with the old key, and then encrypt passwords with a new key for ASP.Net membership users?
View 2 RepliesI have been killing myself over this for a couple weeks now and cannot find a viable solution. Here's my scenario:
I have a DTSX package that imports user data from an external database. It then creates user accounts and profiles in the local database. Users can also be created via a custom ASP.NET Membership Provider. The provider must be able to authenticate both types of users.
This was all fine and dandy during development because passwords were stored as clear text. However, now that we're ready for release the passwords format of the provider must be set to encrypted and so the users created via the DTSX must be created with an encrypted password. (I'd prefer the passwords were hashed but the client's requirements are that passwords be recoverable). The real problem seems to be creating an encrypted password within the DTSX that will be decryptable by the ASP.NET Membership Provider.
My original solution was to have the DTSX call a CLR stored procedure that had access to the same encryption logic as the provider. I got it working but our client wouldn't enable CLR integration. So that's out the window. Now I'm investigating alternatives. One alternative is to simply use the built-in encryption methods of T-SQL. But how do I share the keys used for the encryption/decryption?
My question is, is it possible to generate a password in T-SQL, say using EncryptByKey, that will also be decryptable by my provider? This means that the key in SQL must match the key in my machineKey configuration.
I've got a system that was partially written by someone else and is a complete maintenance nightmare for such a small app. I've finally been given changes which justifies just rewriting the horrible mess so I am moving it to Django.
Before I take the plunge, I've been trying to move over the password hash and salt into the Django auth tables [sha1]$[salt]$[hash] but can't get it to hash properly (resetting passwords isn't really an option).
Here is what I've been able to find out so far:
ASP.NET stores the hash as base64 string and uses a base64 salt (before hash) I can obviously reverse the base64 hash to a byte array Django uses a hexdigest, I tried BitConverter.ToString but they hash differently

I also have the key used to generate the string:

And I found the following solution to decryp and encrypt:
Code:
Dim des As New TripleDESCryptoServiceProvider
Dim md5 As New MD5CryptoServiceProvider
'hash function
Function md5hash(value As String) As Byte()
Return md5.ComputeHash(ASCIIEncoding.ASCII.GetBytes(value))
End Function

It works like a charm when i encrypt and decrypt values set by me in the page;
But when i use the value stored in the DB it throws the following error;
"An exception of type 'System.Security.Cryptography.CryptographicException' occurred in mscorlib.dll but was not handled in user code
Additional information: Bad Data."
I am i using the wrong crypto class ? it's a length issue? the string is not base64?
i'm having a problem on how to decrypt an encrypted stored procedure on SQL Server 2008
i've tried asking my workmates but they mentioned that they're forgotten the basic syntax to decrypt
most of the query i can find are for sql server 2005.. are they usable to sql server 2008?
i found this but it doesn't seem to help

I know there are tools out there that will let you see the content of asp.net viewstate. Is it possible to see and modify the content of viewState if it has been encrypted by adding the <machineKey ... /> node to the web.config?
View 1 RepliesMy issue today is that i have a MySQL Database and am using the security framework provided by the ASP.NET Membership and Role Providers...I override the default methods with my own MySQL.
Now the issue comes in when i someone would like to have their password reset. My application is running entirely on an Intranet so i cannot have their passwords emailed to them. Is there a way i can have this information displayed in any way so that the user can use it to Log Reset, Create Accounts or Recover their lost passwords on an intranet without the administrators intervention?
Recently i had an approach as follows. In my web.config<system.net><mailSettings><smtp deliveryMethod="pickupDirectoryLocation" and my location was a folder on C drive as c:/SavedPasswords. Now i understand this was such a big security threat and thats why i am looking for a better option.
I would have that folder created using my System.IO and then the Mail is dropped into that folder. Then after the process is successful, i tell the user to check into that location and Read its content.
Then there is a global variable that is set to true...meaning that the folder at c:/ has been created. then there is a Method in a certain class that once it sees this variable True, it reads the readers c:/ and deletes that folder "save" if it exists;
I have a small database, with a very small number of users. The passwords were stored as clear as the database was so small and held no sensitive data. The database is now to be expanded and passwords are required to be encrypted. I can change the Password Format in the web.config, but is there a way to change the existing passwords from clear to encrypted?
View 1 RepliesI was reading through this post here http://www.misfitgeek.com/op-ed/adding-asp-net-membership-to-your-own-database and thought to my self what the common practice is. What do developers using ASP.NET membership and authorization in their applications recommend as a best practice? creating the membership tables in the same database that stores their applications data or configuring a second database to store ONLY the membership information?.
My current setup is a different database for membership information ONLY but am thinking that increases the number of databases i have to maintain. If I have 5 applications using asp.net membership, then that means 5 more asp.net membership databases. So do you normally create the asp.net membership tables in your main database or you configure a separate membership table? what do you recommend.
Now this might just be straightforward, but I can't seem to figure it out..
I have set up the Custom Membership provider, and gave it the proper connection stuff.
What I know is that it connects to the correct database, but I know for sure that it doesn't look at the correct table.
How would I set it up to use a specific table? As the table already has users in them.
The table name is: members_info.
the column names are: member___id(key), member_name, member__pwd, member_perm
member___id => Being the Key and the account name to login with
member_name => Being the users Name or Nickname
member__pwd => 10 chars long (for now)
member_perm => holds 1 of the following values: 0) User 1)Admin 2)Banned
now I know that the later one is to be setup by the Role Provider, and I'm sure once I know how to do the membership one that one is similar in some way.
So my question is, how do I point the Custom Membership Provider to the table: members_info and to use member___id for username, members__pwd for password (and possibly get member_name out to say: Welcome {member_name}! when they login).

Added info.
Members__uid is the key value as it increases on each new entry.

Since you can't tell it to use a specific table
How can I set it up so, that it works with the tool provided in visual studio? (Website > ASP.net Configuration).
As it now says 0 users, on the security tab. I want to be able to manage the users through here too.
How can I sync up the aspnet membership tables among 2 different databases?

ds = Wservices.SelectBulkUsers()

For Each dr In ds.Tables(0).Rows

Dim newUser As MembershipUser = Membership.CreateUser(username, password, email, "", "", True, status)

Roles.AddUserToRole(username, "normal user")
Case "2"
Roles.AddUserToRole(username, "administrator")

Roles.AddUserToRole(username, "super administrator")

If newUser Is Nothing Then
errorMsg = username & " - " & status.ToString & "<br />"

Next
litResult.Text = errorMsg

I thought everything was fine and then went through the labourious task of replacing all the usersids used a as a foreign key in all the tables. It was only after doing this and trying to log on I couldnt, and noticed the membership table was empty. I assumed (stupidly) as it had done the users/ roles it must have done the membership. As I have already re-assigned the old user ids I dont want to import again as the userid will chnage. So my question is: Can I create a membership for each of the users in my aspnet_users table? I have the passwords etc in varchar fields at min from old table.
I am using aspnet_regsql.exe to add membership tables to my database.
when I click the exe file it just opens up an XML file in visual web developer and does not start the wizard to merge the databases.
the run command where file is located is below

I just get the file below opening instead

Lets say that I have a database set up with a load of info in it and I decide I want to add the membership and roles functionality to my site but my hosting provider makes me pay for each database I use. I don't want to pay for another db, so how do I set it up so that instread of creating membership and roles tables in the the aspnetdb database, it creates them in my existing database?
View 5 RepliesI want to add custom columns to some tables created by ASP.NET. For example; I need to add two fields such as FirstName and LastName to the aspnet_Membership table.
I can add this directly by editing the table but;
Is this the right thing to do (I mean; extending the table directly) OR should I create a separate table and hold the extra user data, there?How can I see these custom database fields as properties in code completion? example: membershipuser.FirstName;
I want to rename aspnet_application table and its columns. 1- Does membership framework allow me to do that ?2- Will there be any problem in accessing System.Web.Security functions ?3- I have to change procedures and functions etc ?
