Encrypt home directory only I have a shared computer that is primarily for my use, but occasionally when I'm out of the office others would like to use it. 

These others require Administrator access to be able to install software etc. but I'm concerned (just as much out of mistake as anything else) about the security of my personal stuff on the machine. 

I'm looking for a means to encrypt my home directory that can only be unlocked by my password. 

Obviously FV2 doesn't cut it, as the full drive is decrypted as soon as the other user logs in.
If you do not want to encrypt the whole home directory but only a few files/directories you could use something like Hider. It's paid though.
