I need to be able to accept a password from a user in a WPF app, encrypt it then store this in a database and be able to decrypt later on. However I'm not sure how to implement this.
This is completely trivial so whether it's safe or not doesn't matter. All I need is for it to get working only I'm unsure exactly how to do it. I've tried playing around with the DESCryptoServiceProvider() but haven't gotten anywhere.
To be clear, how exactly do I go about converting a simple password into something that's been encrypted and storing it in the database (and what fields would I store it in). At this point, I'm happy if there's only one key and that key is being defined in the source code.
I m creating a Log In form at VB.NET and i have some problems The connection between the application and the web server opens fine and i can login if i use the MD5 encrypted text of the database.

I am wondering if it is possible to read in the encrypted value of a Windows users password so I can preload a textbox with the value? I have a checkbox on my .NET form -> Use Workstation Logon. When the user checks this box, the username and password fields are populated respectively.

View 1 RepliesI've password protected an mdb file but then I cannot access it on vb.net. I don't know the correct code for defining the password.this is my current code, I know its wrong, but I don't also know the correct code:
conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=F:search.mdb;pwd=nit"
A want connect to MS Access database 2007 (.accdb) with Vb.net I set A Password On My DataBase.I Use Code:
TxtPasswordDB.Text = "123"
ConnString = "Data Source=" & Database_Full_Path & ";Provider=Microsoft.ACE.OLEDB.12.0;persist security info=False;
Jet OLEDB:Database Password=" & TxtPasswordDB.Text & "
[code]....
but not Open Connection !
I'm trying to use two different methods of connecting to a database to edit data, the declaration below is working:
Dim rsConn As ADODB.Connection
rsConn.Open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" _
& Application.StartupPath & "VFMS_DB.mdb;" _
& "Jet OLEDB:System Database=Security.mdw", "Ads", "1234")
but now I want to do the same thing with the declaration below but I keep getting the message "Not a valid account name or password.
Dim conn As OleDbConnection
conn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" _
& Application.StartupPath & "VFMS_DB.mdb;" _
& "Jet OLEDB:System Database=Security.mdw;Database Account=Ads;Database Password=1234;")
I pretty sure it's because of this ;Database Account=Ads;Database Password=1234; not being correct. I tried ;User ID=Ads;Database Password=1234; and also to make it look like the first statement but neither worked.
My VB.NET program compacts and repairs my DB, but somewhere in the process unsets the database password. No problem, just reset it through VB, right? not sure how to go about that task.
So I either need to know how to compact it without losing the password, or how to reset the password after I lose it. Trying the best I can to make the code look decent in my post, let me know if there is a better way.
Dim strAccessDatabasePath As String = System.AppDomain.CurrentDomain.BaseDirectory & "App_DataSquirrel.accdb"
Dim LockedDbFileInfo As New System.IO.FileInfo(strAccessDatabasePath.Replace(".accdb", ".laccdb"))
Dim TempFolder As String = System.AppDomain.CurrentDomain.BaseDirectory & "App_Data emp"
Dim TempDB As String = TempFolder & " emp.accdb"

Im making just a fun project using visual studio 2010. Its a simple password manager. The issue im having is trying to put the information from my Access database into a gridview.

Here is what i have for this part:
Dim mypath = Application.StartupPath & "\User Passwords.mdb"
Dim password = "password" 'I do have an actual password, im just not going to put it out there
