Lua Requires Chilkat v11.0.0+

Unzip an AES Encrypted Text File directly into a String Variable

See more Zip Examples

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. Lua

local chilkat = require("chilkat")

-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

local zip = chilkat.Zip.new()

-- 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.

local success = zip:open_zip("qa_data/hamlet.zip")
if not success then
    print(zip.last_error_text)
    return
end

local entry = chilkat.ZipEntry.new()
success = zip:entry_of("hamlet.xml", entry)
if not success then
    print(zip.last_error_text)
    return
end
