1. ZIP Method:
Open up a terminal window. Go to desktop and then type the following command “zip -er nameofoutputfile.zip nameoffoldertobeprotected/*” (e for encrypt, r for recursive, the name of the output file zip, then type the folder that you want to protect) I recommend appending a asterisk to explicitly specify the contents of the folder, but this is optional.
Finally, hit enter and type a password. We highly, highly recommend that you choose a long, strong password here because there are tools that can easily figure out short guessable passwords. Go ahead and confirm the password that you just typed, and then you’ll see the zip file get created. Delete the original directory, and if you try to open the file, it will be prompted for a password. Only with the correct password will the file contents be extracted.

Opening the same file on Windows also prompts for a password. But notice how the file and folder names are visible. Examining the contents of the zip file on Mac and Linux also exposes the file and folder names. So if that’s a problem for you, you can try to zip the zip file. Or perhaps a better way is to create an encrypted DMG file, which we will show you how to do.

Finally, click on Save, and a few moments later, depending on the size of your files, an encrypted password protected DMG file will be created for you. We can close out of Disk Utility now and get rid of the original folder. When you open the DMG file, you will be prompted for a password. Only when you provide the correct password will you see the files mounted which have been decrypted and are now accessible. When you’re done with these files, be sure to eject the volume to prevent unauthorized access.
