(AutoIt) Creates an AES Encrypted Zip with One File Unencrypted

Demonstrates how to create an AES encrypted zip, but also containing one file that is not encrypted. The way we do it is to first create an AES encrypted zip in the usual way, and then we append an unecrypted file to it.

; Set properties to indicate that the Zip should be

; A value of 4 indicates WinZip compatible AES encryption.

; Key length can be 128, 192, or 256 bits.
$oZip.EncryptKeyLength = 128

; Set the password for AES encryption:
$oZip.EncryptPassword = "myPassword"

; Exclude the file helloWorld.txt
; This file will be added unencrypted to the .zip

; ----------------------------------------------
; At this point, we have an encrypted .zip with all 
; files except for helloWorld.txt.
; We'll add helloWorld.txt (unencrypted) to the .zip we just created.

; The NewZip method only initializes the Zip object -- it does
; not create or write a .zip file.
