- creating a zip archive, adding files or directories into the archive
- extracting files from an existing archive
- modifying an existing archive - removing entries from an archive or adding new entries to an archive
- password protecting entries in the archive
- getting entry input from a file or a stream
- reading a zip file from a file or a stream
- extracting an entry into a file or a stream
