    This video lays out the steps for creating a very simple encryption and decryption program using free tools. The programming language we will be using is VB Script.  See if you can decrypt this text:

    wkjlue#vnrro#huxwxi#uxr\

     

    The code below is for the encrypting program:

    <—–Start copying below this line—–>
    ‘SIMPLE VB ENCRYPTION PROGRAM
    ‘Create a dialogue box that asks for the text to encode
    set x = WScript.CreateObject(“WScript.Shell”)
    mySecret = inputbox(“Enter text to be encoded”)
    ‘Reverse the submitted text
    mySecret = StrReverse(mySecret)
    ‘Open up an instance of Notepad to print the results after waiting for 1 second
    x.Run “%windir%\notepad”
    wscript.sleep 1000
    x.sendkeys encode(mySecret)’This function encodes the text by advancing each character 3 letters
    function encode(s)
    For i = 1 To Len(s)
    newtxt = Mid(s, i, 1)
    newtxt = Chr(Asc(newtxt)+3)
    coded = coded & newtxt
    Next
    encode = coded
    End Function
