Unzip Encrypted Text into a String Variable

See more Zip Examples

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

import { Zip, ZipEntry } from '@chilkat/react-native'

async function chilkatExample() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  const zip = new Zip();

  // Set the password required for decrypting.
  zip.decryptPassword = 'myPassword';

  try {
    await zip.openZipAsync('encrypted.zip');
  } catch {
    console.log(zip.lastErrorText);
    return;
  }

  // Locate the file within the Zip to be unzipped into a string variable:
  const entry = new ZipEntry();
  try {
    zip.entryMatching('*.csv', entry);
  } catch {
    console.log(zip.lastErrorText);
    return;
  }

  // lineEndingBehavior:
  // 0 = leave unchanged.
  // 1 = convert all to bare LF's
  // 2 = convert all to CRLF's
  const lineEndingBehavior = 0;
  const srcCharset = 'utf-8';

  const strCsv = await entry.unzipToStringAsync(lineEndingBehavior, srcCharset);
  console.log(strCsv);
