; Open an encrypted zip...

; The two main types of encryption used in ZIP archives are Password-Protected and AES.
; 

; ---------------------------------------
; 1. Legacy Password-Protected Zip
; 
; This is the older and less secure method of encrypting ZIP archives. 
; It provides a basic level of security, but is considered weak by modern standards. 
; It is vulnerable to various attacks, including known-plaintext attacks and brute force attacks.
; Although Chilkat allows it, you shouldn't create new zip archives using legacy password-protection.

; ---------------------------------------
; 2. AES Encrypted Zip
; 
; AES encryption is a more modern and secure method for encrypting ZIP archives. 
; It provides strong encryption based on the AES algorithm, which is widely regarded as secure. 
; AES supports different key lengths, typically 128-bit, 192-bit, and 256-bit.

; When opening an encrypted zip, your application only needs to provide the correct password.
; The information about the type of encryption and the key length (if AES) is already embedded within the encrypted .zip.

; Provide the decrypt password because we are opening an existing .zip (decrypting)
