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. Perl

use chilkat();

$success = 0;

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

$zip = chilkat::CkZip->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.
$zip->SetPassword("secret");
$success = $zip->OpenZip("qa_data/hamlet.zip");
if ($success == 0) {
    print $zip->lastErrorText() . "\r\n";
    exit;
}

$entry = chilkat::CkZipEntry->new();
$success = $zip->EntryOf("hamlet.xml",$entry);
if ($success == 0) {
    print $zip->lastErrorText() . "\r\n";
    exit;
}

# lineEndingBehavior:
# 0 = leave unchanged.
# 1 = convert all to bare LF's
# 2 = convert all to CRLF's
$lineEndingBehavior = 0;
$srcCharset = "utf-8";
$xmlText = $entry->unzipToString($lineEndingBehavior,$srcCharset);
print $xmlText . "\r\n";
