[plug] encyption

[Alex Polglaze]

G'day All,

Here's the question.

I was at a mates place on the weekend, he runs XP, I run Linux.

He asked me could I encrypt a single file on my system to prevent 
unauthorised access. I wasn't sure, but I said that I would find out.

But it did get me thinking.

Can you do it under Linux or XP for that matter.

Alternatively, can you encrypt a whole folder, (windows term) with the 
same effect.

TIA
