How to Encrypt files in Debian Etch 64 bit.
Mon, 24/11/2008 - 01:10 — paulIntroduction.
Further to my page offering a "how to" on encrypting emails, this page deals with encrypting files.
There are any number of reasons you may wish to encrypt individual files, for example, maybe you have sensitive customer data, perhaps a client list or cost price tables that if they fell into your competitors hands, would amount to a gold strike.
I will repeat here, it is my belief, all company laptops should have some form of encryption. Ideally, the whole drive should be encrypted, but that is not the subject of this page.

What is a firewall?Just as a building has a firewall and possibly a fire door to try to isolate a fire on one side of the wall, preventing it spreading to the other side, a computer firewall does much the same. However, it's not concerned with fires, but more to the point, unauthorised entry and use. It most commonly, sits between the computer and the Internet, although in complex networks, there can be others within the overall system.
