[Visual Basic]Text to MD5[Tutorial]

[Coding Support]

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

Code:

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        TextBox2.Text = StringToMD5(TextBox1.Text)
    End Sub
    Private Function StringToMD5(ByVal Content As String) As String
        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

You are done, Test is by using the word hi.
It should look like this
