Unzip Encrypted Text into a String Variable

Demonstrates how to open an encrypted .zip archive and unzip a text file directly into a string variable.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

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();

// Set the password required for decrypting.
zip.DecryptPassword = "myPassword";

success = zip.OpenZip("encrypted.zip");
if (success == false) {
    console.log(zip.LastErrorText);
    return;
}

// Locate the file within the Zip to be unzipped into a string variable:
var entry = new CkZipEntry();
success = zip.EntryMatching("*.csv",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 strCsv = entry.UnzipToString(lineEndingBehavior,srcCharset);
console.log(strCsv);
