Create Password Protected Zip

Downloads for Windows/Linux and Install Instructions

Ruby script to create a password-protected Zip. (Password protection is the original / older style of Zip encryption. It is not secure. See the example for WinZip compatible AES encryption for instructions on how to create a strong-encrypted zip.)

# file: ZipPasswordProtected.rb

require 'rubygems'
require 'chilkat'

# Create a password-protected zip.  (Password protection is the old-style
# Zip encryption.  It is somewhat insecure.  It is *not* AES encryption.

zip = Chilkat::CkZip.new()
zip.UnlockComponent("anything for 30-day trial")

zip.put_PasswordProtect(true)
zip.SetPassword("secret")

zip.NewZip("passwordProtected.zip")
zip.AppendFiles("exampleData/*",true)
zip.WriteZip()
