Sending an encrypted folder via email

I have two .pdf documents (each 10 pages) containing sensitive financial data which I need to email to someone (who has a Windows PC). Is there any way I can encrypt/make a .dmg/or anything else that would require a password for the attachments to open? And, of course, it would have to in a format a Windows user can open. If that is possible, I'd be emailing the password separately.

Hope there is a way - thanks for any input.

Open the pdf's in preview. Save each of them as. Choose a new name or new location, check the box to encrypt. click save. choose your password and verify it. Do this to both pdf's. In the finder, select both of them, right click and choose "compress 2 items" this will create a zip of the two files. There are many programs available for windows that can extract zip files, I have never com across a computer without one, I actually think there is an inbuilt feature. When the recipient gets the zip, all they have to do is uncompress it, and enter the password fir the pdf's that you have set. Just don't forget to tell them the password.

Thanks, I looked at that, but I couldn't find it on Versiontracker and it's somewhat dated (from 2003), so I wouldn't trust it enough to actually install it on my baby.

Thanks so much for trying though! I wish that option would be part of the OS (Disk Utility?) - I tried everything there and could either create a blank .dmg in a Windows format or create a Mac OS .dmg from my folder - but couldn't combine those two.

The '-e' in the command provided above tells the zip application to prompt the user for a password to use to encrypt the zip file. When you execute that command to create the zip file you will be prompted to enter a password.

Later if someone tries to open (or unzip) the .zip file they will be prompted to enter the password before the file is opened (unzipped).
