The good folks at http://truecrypt.org have released version 4 of Truecrypt (encrypted volumes) which now supports Linux, via device-mapper and a kernel module (open-source, of course). I had previously used their version 3.1a on win2k with good results. On my dell laptop, I run windoz and Debian Linux (sarge), and it has always bugged me that I didn't have an encrypted volume that I could mount from either system. Well, now I do!! I created a truecrypt volume that I can mount from both Linux and Windows. The volume is formatted FAT and is stored in a file on a FAT partition. I used FAT because I don't completely trust NTFS support on linux yet. I had to compile the Linux binaries myself, but it was not to difficult (I already had the kernel source installed).
