I'm pleased to release a small java utility and a small paper.
The java utility is HideMe and it's a small encrypt/decrypt program only for text files.
The system is not so strong... so don't encode you credit card number with it!!!!!
The second is a paper. I've written this paper to make black on wite some advices to protect your systems from local attacks (when the cracker gaign a phisical access on your machine).
The paper is extensible.... so it may change in future!
(The paper is not an official paper or a standard. Take it as an example).
