Encrypting File System Options for Mac OS X?

fieldmouse asks: "I recently had a laptop running Mac OS X stolen. Despite the fact that I got it back, that incident has me looking for an encrypting file system for Mac OS X; preferably one that would create a psuedo drive that I could unlock once when I log on. Anybody have any suggestions?" About 2 years ago, Ask Slashdot did the Linux version of this question. Has this gap been filled in Apple's latest OS offering?

Besides, he is stupid. crypt has very weak encryption.

CFS

Use Matt Blaze's CFS. It supports encrypted (3DES) volumes, with timeout support among others. It's NFS loopback mount, so it will work on pretty much any UNIX -- including MacOS X and *BSD. NetBSD has TCFS which is AFAIK more tightly integrated (at VFS level).

Re:Use Disk Copy and stay neat

Disk images in OS X can be mounted with the hdiutil command. I've never tried mounting an encrypted disk but given the way that Apple implement their crypto using CDSA I expect that it will simply offer up the usual dialogue boxes and let you type in the key (since the prompts for passphrases to CDSA are generated by the kernel code).
