JavaScript 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. JavaScript

var success = false;

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

var zip = new CkZip();

//  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("qa_data/hamlet.zip");
if (success == false) {
    console.log(zip.LastErrorText);
    return;
}

var entry = new CkZipEntry();
success = zip.EntryOf("hamlet.xml",entry);
if (success == false) {
    console.log(zip.LastErrorText);
    return;
}

//  lineEndingBehavior:
//  0 = leave unchanged.
//  1 = convert all to bare LF's
//  2 = convert all to CRLF's
var lineEndingBehavior = 0;
var srcCharset = "utf-8";
var xmlText = entry.UnzipToString(lineEndingBehavior,srcCharset);
console.log(xmlText);
