I want to be able to lock a file so that noone can open it without a password.... any idea on how to do this? I know there used to be an encryption function in OS 9... it never worked well for me tho...

anything similar in X?

    Try an encrypted disk image.

    ok, i just tried that... and it asks me for a password when i first make the disc image... but after that, i can open it and see what is inside w/o having to enter anything

    is that the way it is supposed to work? doesn't seem very secure at all to me... anyone could just go onto my computer and open it...

    any other ideas?

    Encrypted disk images work like this. You enter a password when you create it and have to enter that same password whenever you mount it. Once mounted, you have complete read and write access to it. Unmount it and it's completely secure. As long as you don't check the "remember password (add to keychain)" box, you'll have to reenter it each time. This is the preferred way.
