Why is ZipArchive setEncryptionName not working?

I have PHP v7.3 and I'm running the following PHP code, trying to create a password protected ZIP-file.

The ZIP-file is created, but it's not password protected. What could be wrong?

    $zip = new ZipArchive();
    $zipFile = $this->backupDir . '/' . $db_file_name . '_' . $this->backupFormat . '.sql.zip ';
    if (file_exists($zipFile)) { unlink($zipFile); }
    
    $zip->open($zipFile, ZipArchive::CREATE);
    $password = 'top-secret';
    $zip->setPassword($password);
    $fileName = $this->backupDir . '/' . $db_file_name . '.sql';
    $baseName = basename($fileName);
    $zip->addFile($fileName, $baseName);
    $zip->setEncryptionName($fileName, ZipArchive::EM_AES_256);
    $zip->close();

I'm not getting any errors. It's just that he generated ZIP-file is unprotected.

Solution

  • When checking out phpinfo, you see libzip version is used. This must be increased to version 1.2.0 or newer.
