Easily access remote files on encrypted disk images Network
I store important passwords and financial information in a text file in an encrypted disk image (created using Disk Copy) on my main computer. I often need to access this file from my laptop via an Airport network or LAN. Previously, to do this I had to (1) log into my main computer using "Connect to Server" to mount my main hard disk on my laptop, (2) locate the encrypted disk image and double click to mount it on my laptop, and (3) open the text file to read the information.

I just discovered a much easier solution which demonstrates the amazing integration of AFP, Disk Copy, and the Keychain under Jaguar (the only place I tested this):

Follow the steps (1) to (3) above (you only need to do this once), and place an alias to the text file on your laptop. The next time you want to access your file on the encrypted disk image (even if the main computer's disk is not mounted), simply double-click on the alias. Mac OS X will automatically mount the main computer's hard disk, decrypt the disk image and mount it, and then open the text file with the TextEdit app! Amazing. This only works if you have the login password for your main computer and the password for the encrypted disk image in your laptop's Keychain.

You will need Mac OS X 10.2 or higher to do this. Earlier versions do not resolve aliases pointing to disk images.

Defeats the purpose though

This procedure, while convenient, defeats the purpose. Anybody who gets a hold of you laptop, may be able to get into your account. Once in there, opening the alias opens the secret door to all your other stuff. [Assuming that you do not have a firmware password, do not disable booting into single user mode, automatically unlock the keychain when you log in.]

I keep my sensitive (important) passwords, etc. out of KeyChain, even though it's a hassle to type them in every once in a while.

Don't forget that you can lock your keychain. Also, you can set it to lock automatically after a few minutes or when the computer goes to sleep. (See the "settings" menu item in the Edit menu of the "Keychain Access" utility.) If you put the keychain menu extra in your menubar it's easy to lock/unlock it when you need to do so.

Mostly works via web browser

As mentioned in an earlier hint, in Jaguar you can click on a link like this: disk://mithras.homeunix.net/encrypted.dmg and automatically mount a remote disk image. It also works with encrypted images, and you can store the password in your keychain. I'm not quite sure why you want to do this, but it's pretty cool. P.S., you can open the top-secret image above with the password 'encrypted'
