    I used to use Keka in Snow Leopard to encrypt files, but Keka doesn't seem able to encrypt in Mountain Lion.

    Is there a FREE way to encrypt files in Mountain Lion?

    RE: GnuPG...

    Hi 2012Tony2012,

    The GnuPG package (gpg2, gpg-agent, etc.) is free and runs under Mac OS X, various Linuxes, Windows, and various Unixes. You can encrypt and decrypt on any system that you wish.

    You also get to choose the length of your public key/secret keys, so you can make it as secure as you wish. And you can publish your public key on the Internet so anyone can find it. I currently use 2048 bit keys for my own encryptions. I believe the longest PK that has been cracked so far is 64 bits, and that took something like 5 years of effort. They have been working on cracking a 72 bit key for the last 6 or 7 years using the spare cycles on thousands of PCs and are only about 2% done.

    Regards,
    Switon

    Of course, if Shor's algorithm is implemented on a quantum computer at some time in the future, then these encryption schemes will immediately become vulnerable to attack...

    You can use Disk Utility to make an encrypted image (DMG) and put the file inside that DMG.

    Yes, this right here. This is what I did.

    It's actually really simple to do, and once it's in place, you simply use one password to mount the encrypted image as a drive which you can see in Finder. Then you can use it just like you would an external drive. When your'e done, you just eject/unmount it and now you have one large encrypted file with all your stuff in it.

    How do I open that in MS Windows? Because I want the encrypted files to be able to be opened on Mac and MS Windows.

    You can't. I did not realize you needed to open the files in Windows also.

    Yes I need MS Windows ability too in case my Mac dies and I need access to my files, then I just decrypt them on the MS Windows laptop.

    Any other ideas?

    So you need a cross platform encryptor and decrypter?

    I'd definitely recommend Truecrypt

    Cross platform and works really well for OP's intended purpose.

    Is there a Windows client for it? One of the OP's requirements is that there be cross-platform support with Windows. It wasn't in his original post but it was in one of his subsequent posts...
