To use GPG is another way to encrypt your important files, as an alternative to encfs and mcrypt. There are of interfaces

graphics to create GPG keys. For those who use Gnome, seahorse, for those using KDE, kgpg. In this case, use the terminal.

First you need to generate the key with the command:

gpg --gen-key

At this point we answer the questions that appear on screen, and insert our data, such as name, email, etc. etc.

choose a password, and begin to move the mouse until the password has not been created., there must

A message like this:

<span > We must generate a lot of random bytes.</span> <span > It's a good idea to do some other action (type on the keyboard, move the mouse, use the disks) during the generation of prime numbers, this gives the random number generator a better chance of collecting enough entropy.</span>

Now we are ready to encrypt a file using the name we have chosen at the beginning of the creation of the key.

Figures:

gpg-e-r test.txt edmond

or alternatively:

gpg --encrypt --recipient edmond prova.txt

Decrypt:

gpg --output prova.txt --decrypt prova.txt.gpg

oppure:

gpg --output prova.txt --symmetric prova.txt.gpg

T his is a guide for creating CD / DVD encryption. So for my data set do not find anyone, first of all let us not forget the password ourselves, otherwise the cd / dvd we can throw it, since there is no way to recover it, at least not in earth time. Remember that the password must be at least 20 characters. Then install the necessary with:

apt-get install aespipe mkisofs loop-aes-utils

Now we create an image file. Assume you have a folder of pictures you want to protect, then later burned. The folder called into question the image (not fantasy), we have the possibility to use a key to 128 or 256 bits, of course we will use that to 256 bits. Then:

mkisofs-r photos | aespipe-e aes256> foto.iso

Now enter the password, being careful

Create a directory where to mount the ISO image

mkdir / mnt / iso

load modules

modprobe aes

modprobe cryptoloop

foto.iso mount-t iso9660 / mnt / iso-o loop = / dev/loop0, encryption = aes256

Now we are ready to burn the iso, regardless of whether our burning program gives some error like this:

At this point we will have a CD encrypted to have access must mount it with:

mount-t iso9660 / dev / cdrom / mnt / iso-o loop = / dev/loop0, encryption = aes256

clearly reminding passoword.

O stating that each of us, more or less, is jealous of something, or at least, has some things he wants to keep confidential, I for

have always been an example set for the privacy and security in general, so I always tried to protect

my data. So for the set, the faithless, or lovers porno now talk about TrueCrypt. The peculiarity of

TrueCrypt is defined encryption / decryption on-the-fly, which means that the data within a volume are

encrypted / decrypted automatically a few seconds before being read or written without the direct intervention of the user. To access

the protected volume, TrueCrypt requires a password, created earlier, at the time of installation. So before

installing grab the sources from here, or for those who use Ubuntu and openSUSE are packages

precompiled. Here I show you the procedure done by me on Debian Lenny. First install a dependency,

that is, a tool for volume management

apt-get install DMSetup

I downloaded the source on the desktop then:

cd Desktop

tar xzf truecrypt-4.3a-source-code.tar.gz

cd truecrypt-4.3a-source-code

Linux CDs

compile

. / build.sh

If all went well, we get this:

Debian: / home/edmond/Desktop/truecrypt-4.3a-source-code/Linux #. / Build build.shChecking requirements ... Building kernel module ... Done. Building truecrypt ... Done.

install

. / install.sh

now begin to create the encrypted volume

truecrypt-c / home / Edmond / volume-cryptato

screen will appear to you a few questions to start you can answer that:

We then create a folder for the mount

mkdir / mnt / folder-cryptata

proceed with the mount of the file created (volume-cryptato) we find in our / home

truecrypt-u-volume cryptato / mnt / folder-cryptata

from this moment on, we can copy files or create folders within the folder-cryptata, safely.

to dismantle

truecrypt-d volume-cryptato

Must be careful not to forget the password, Asthe if you forget, there's no way to get it.
