<![CDATA[Which lib should I use when I want to zip multi-folders and set it a password ?]]>Hi,everyone .
I just want to generate a .zip file of 4 folders (in which is filled with many .png files),and I want to set a password of this .zip file,so I searched some choices on the Internet.I found QuaZip but it doesn't have a password-add-in function until now.
Is there anyone having any advice on that?

You will have to use the C API of zlib directly. Instructions can be found here: https://falsinsoft.blogspot.co.uk/2012/03/create-password-protected-zip-file.html

Be sure to use the latest version of the libraries as there's a bug in previous versions that decrypt the files even if a wrong password is entered
