[Visual Basic]Text to MD5[Tutorial] - Coding Support - 06-18-2011

This will teach you how to make a program that converts text to an MD5 Hash

Anything in Pink In my tutorial is important...

Step One(The GUI)

This part is simple. Just make the GUI Look similar to mine and move on to the next step(Step Two)

My GUI (Click to View)

Step Two

Step Two will be coding the Convert Button.Double click it and input this code...

Code:
textbox2.text = StringToMD5(textbox1.Text)

Under the End Sub, put this code in...

Code:
Private Function StringToMD5(ByVal Content As String) As String

You should Have This code...

Code:
Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        TextBox1.Text = StringToMD5(TextBox2.Text)

    End Sub

    Private Function StringToMD5(ByVal Content As String) As String

End Class

Step Three

Under Your private function, use this code...

Code:
Dim M5 As New Security.Cryptography.MD5CryptoServiceProvider

        Dim ByteString() As Byte = System.Text.Encoding.ASCII.GetBytes(Content)

        ByteString = M5.ComputeHash(ByteString)

        Dim FinalString As String = Nothing

        For Each bt As Byte In ByteString

            FinalString &= bt.ToString("x2")

        Next

        Return FinalString

    End Function

Final Code

So how can we un-ecrypt the MD5? :-/ ?

That would be called bruteforcing.

It's not encrypted, it's hashed. Since hashing is a one way process, it is impossible to get the original value from the hash.

you forgot the end class statement in the final code

but otherwise good job
