Protecting files in linux

[Jorge Delgado]

Hi, i would like to protect files like passwords and websites of Firefox
(iceweasel), and this cannot be done encripting the files.

So, i need some program for protect the files and, at the same time be
using them. If i encript the files, i cannot use them at the same time.
And if I cannot use them at the same time, it's meaningless.

Somebody could help me? Thank you very much, I appreciatte your help.

Do an eSearch (TM) on "Linux ACL".
ACL is not encrytion
ACLs restrict file access in a  per user basis. You could make the files
inaccessible to others while the files are accessible to you only.
The filesystem where you want to implement ACLs must be mounted with
the acl option.

What's wrong with the built-in password encryption in Firefox? Look
under Preferences->Security->Use a Master Password. You can even use a
secure access card if you know how to set it up.

There are also external (to Firefox) password-storing apps, or even
strategies like storing password files on pendrives. I store important
ones on a PDA (encrypted of course :-) This trades security for
convenience, since you have to type them in.

You need to state more clearly what you're trying to protect against.
