My TrueCrypt experience:

I have a new 810 running Diablo.

I went to http://www.securix.net, followed the instructions to install 6.0a, but the program seg faults when I run it.

So I tried installing 5.1a. That one was running fine. Getting all excited I wanted to check how much room I had left to put an encrypted volume into.

So I ran the "DiskUsage" app (from maemo.org), clicked on one of the volumes, and the app crashed. I put libstdc++.so.6 back the way it was before, and the DiskUsage app started working again (so basically, upgrading libstdc++.so.6 is evil and breaks things).

So being turned off breaking my existing software for 5.1a, I went back to 4.3a. Tried installing the deb, and it tells me it can't install, and requires "e2fsprogs". So I try to "apt-get install e2fsprogs", and it says it's not available.

Brick walls in every direction.

In lieu of using truecrypt, is there any more tried and true way to encrypt\decrypt files on Diablo? Surely the desire for security on a portable computer is more common place than to only be available in the realm of hackers?
