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 method

On 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!
