    I don't know about zips, but there was a way where you could protect a map with a password protection via disc utility..

    Note that the zip format does not include the concept of having a password. So zips with passwords are non-standard by definition. So they will mostly only work with the program that created them.

    You can easily password protect a zipfile on your mac without any third party software... however to open a password protected zip file on a mac you do need a third party program like Zipeg.

    Using terminal(Terminal is found in the Utilities folder inside Applications, it is basically a mac osx version of cmd prompt on windows)
    simply enter the command below in the format specified.
    zip -e file1.txt file2.txt
    you will be prompted to type in a password, this is the password used to protect the zip file. you can also specify where to place the zipfile using the same syntax as you would to specify where the files are.

     zip -e /users/<username>/Desktop/ /users/<username>/Documents/file1.txt /users/<username>/Desktop/file2.txt 
    note that .txt can be substituted with any extension and "<username>" should be replaced with your username(case sensitive) you can also in mac osx snow leopard simply drag and drop the file into terminal to get a link to file location automatically placed in(i suggest this method to avoid errors spawned by not matching case ie file not found does not exist)

    4 years on and just in case someone does a google and gets this page

    I googled! How did you know :rolleyes:

    For those of us who just don't do a lot of Terminal-ly things and don't want to figure out how to change directories and stuff, the easiest way I've found to password-protect a zip file is just using Keka, a free Mac app at

    All I had to do was open the app, type in my password that I want on my .zip file and just drag and drop the .zip file onto the app in my dock.

    Voila! The encrypted .zip file appears in the same folder as the un-encrypted .zip file.

    I can open the password-protected .zips with StuffIt Expander.

    I've thrown a couple of $$$ towards the developers for this. It really lessens the anxiety of putting more sensitive things into my Dropbox, especially into my public folder that a group of people have access to but also has a file I want some control over.

    Yeah... I know the omnipotent 'they' could crack anything I had in there but it's more for my sanity than any heavy-duty security :D
