I have recently opened a discussion about something similar.

The program you can use is "encfs", and there is a fantastic GUI for
managing it called Cryptkeeper. Both are in Debian repositories.
You can create, for example, an encripted folder called "net", and then
_move_ the folders ".mozilla*" inside it. Then create a symbolic link
against them to your folder, and voalá, you have protected your files
_while_ you can use them.

Why not?

Certainly not. Any encrypted file with no means of decrypting it again
is just useless. The idea of encryption is to prevent *unauthorized*
access, not to prevent all access (then you might just delete the file).

Why?

What is it actually that you would like to achieve?

I am not sure what you are trying to accomplish, but in Firefox
preferences, go to the security tab and there is a check box
"use master password". If you turn this on, when you start a fresh
session in FF, the first time you go to a website that FF has a
saved PW for, it will ask for the master password to decrypt the
saved PW file. Once you enter the master PW once, all user
names and passwords will be filled in automatically, until you
close FF.

Apologies if you are after something completely different .

My objetive is, for example, restricting all access except exceptions
(Firefox), do you understand?

Thank you very much, I appreciate your help.

Default Protecting files in linux

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.

I guess you mean those files containing such information to be encrypted
if someone steal your PC ...

You may wish to consider encrypted filesystem. Easy one is encrypted
home or root.

Hints are here but you need some customization etc.

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.
