This example creates a ZIP file archive test.zip and add the file test.txt encrypted using the AES 256 method.
Beispiel #1 Archive and encrypt a file
<?php
$zip = new ZipArchive();
if ($zip->open('test.zip', ZipArchive::CREATE) === TRUE) {
$zip->setPassword('secret');
$zip->addFile('text.txt');
$zip->setEncryptionName('text.txt', ZipArchive::EM_AES_256);
$zip->close();
echo "Ok\n";
} else {
echo "KO\n";
}
?>Hinweis:
This function is only available if built against libzip ≥ 1.2.0.
Files compressed using this function on Linux won't be decompressed using Windows.
There seems to be some incompatibility with Windows built-in decompressor.
There's an alternative library that works better here: https://github.com/Ne-Lexa/php-zip
I got windows to open a file created with it by using the PKWARE encryption methodOn windows is the "EM_AES_256" by default not supported, but you can use winrar, winzip or 7zip.
At first we had a password of 128 chars (this was to long) and all extract applications give an error that the password was incorrect.
The next time we did use a password of 52 chars., this time i did work!
