[RESOLVED] Help with a Hash Password

Hello evryone:



I am new in programming and I am using VB2005.

I have a program where I have created an Add new user form and a Reset Password form.



When I create a new user I have setup a default password "Support", I have setup an IF statement that when the user logs in that if the password = 'Support" to bring up the Reset password form, where they would create a new one of their own



I have added a HashPassword feature to my code: The code to hash the password is the following:

HTML Code:

---

Private Function HashPassword(ByVal password As String) As _
    String
    Dim hash As String = ""
    Dim i As Integer
    For i = 0 To password.Length - 1
        hash &= Chr(Asc(password.Substring(i, 1)) + 1)
    Next i
    Return hash
End Function

---

In the OK event when I first login I have the following:

HTML Code:

---

IF TextPassword.text = "Support" Then

Msgbox = "Please change your Temporary password now", vbOKOnly

ResetpasswordForm.Show()

Exit sub

End if

---

The problem is that is, if I type "Support" under tha password textbox, it doesn't display the resetPasswordForm, it just take me into the program.



What am I missing?



Thanks and I hope I am making sense.

If you really want to calculate a hash, you should use a real hash algorithm. .Net has some built in, like the MD5 hash:

You should also consider adding some salt to your hash, so it is not the same for two identical password values.

This line:

Code:

---

Msgbox = "Please change your Temporary password now", vbOKOnly

---

Should not even compile. If you want to show a messagebox, use

Code:

---

MessageBox.Show("Please change your password now.","Change Password", MessageBoxButtons.OK)
