You can do this on the command line (in the Terminal Application) without any other software.
zip -r -e misc.zip ./misc
The command above takes the entire contents of the ./misc folder (-r means recursive) and creates misc.zip in the current directory.
unzip misc.zip (it will prompt you for the password)
To unzip from the Finder, you’ll need Stuffit Expander (currently there is a free download at http://www.stuffit-expander.com)
