See #327 (closed)
This and felipeborges/gnome-autoar@ab7b7fc5 are the patches I have been using locally to be able to extract password protected zip files.
I am keeping this as WIP because I am yet to introduce the handling of wrong passwords.
After that, we might as well have to iterate a bit on the design and extra functionalities (like storing the password in the keyring or as gvfs metadata or something).
To be continued!
