LWE10134 : Howto encrypt vbs or js scripts so you cannot read them anymore

Symptom:

You need to encrypt a script because you used a password in cleartext in it

Cause:

You do not want your script to be readable by users

Solution:

You can use the free microsoft script encoder to encrypt your scripts. You need to download the tool and install it first.

After installation you can encode a script with the following syntax:

SRCENC [switches] inputfile outputfile

You can encode 4 kinds of files:
1. ASP (asp, asa and cdx)
2. HTML (htm and html)
3. Plain text (js and vbs respectively)
4. scriptlets (sct and wsh)

Example:

You can copy and paste the following and save it as hello.vbs

'--------------------------
'For the Lubby project
'by Wim Peeters
'
'**Start Encode**
WScript.Echo "Hello, world"
'--------------------------


If you run this script it will just say "Hello, world".

Now we will encrypt it with:

E:\>"C:\Program Files\Windows Script Encoder\screnc.exe" "e:\hello-world.vbs" c:\temp\hello.vbe

The encrypted script c:\temp\hello.vbe looks like:

'--------------------------
'For the Lubby project
'by Wim Peeters
'
'**Start Encode**#@~^PgAAAA==@#@&j1DbwYc214W,Ju+^VGS,hWMsNr@#@&ERRO O ORORR ORO RO ORR OORLA4AAA==^#~@

The encoded script can be used just as the other one.

E:\>c:\temp\hello.vbe
