Unzip an AES Encrypted Text File directly into a String Variable

A common need is to unzip from an AES encrypted Zip archive directly into a string variable, such that the unencrypted file never resides on disk, even temporarily. This example shows how to do it.

require 'rubygems'
require 'chilkat'

zip = Chilkat::CkZip.new()

#  Any string unlocks the component for the 1st 30-days.
success = zip.UnlockComponent("Anything for 30-day trial")
if (success != true)
    print zip.lastErrorText() + "\n"
    exit
end

#  This example opens a WinZip-compatible AES encrypted
#  .zip that contains a single file: hamlet.xml.

#  It decrypts and unzips hamlet.xml directly into a string
#  variable.
zip.SetPassword("secret")
success = zip.OpenZip("hamlet.zip")
if (success != true)
    print zip.lastErrorText() + "\n"
    exit
end

entry = zip.GetEntryByName("hamlet.xml")
if (!(entry == nil ))
    xmlText = entry.inflateToString2()
    print xmlText + "\n";

else
    print "Failed to find entry in zip" + "\n"
end
