I want to get some information on using file system encryption. For instance..if i backup some files on a tape on one linux computer and take it to the other computer and try to install it...it works!! right??
how can i make it to encrypt everything so if i take the info to the other computer it has to be de crypted before it gets opened??

Please advice!! ???

Hmm, I have never played with linux file system encryption. The document you find floating around is antique.

Red Hat did include support for encrypted filesystems in their 2.4.18.* kernels in 8.0. They didn't provide any docs on it either. :-\

I think the GPG (GNU privacy guard) can be used to encrypt files. It's the free implementation of PGP (pretty good privacy) and is downloaded at www.gnupg.org. The latest version is 1.6.0 and was released 3 weeks ago.

Yes, you can use gpg to encrypt individual files. An encrypted filesystem allows you to encrypt an entire drive and swap space.

I just turned up this link in a google search. The information is actually very recent.
