To use GPG is another way to encrypt important documents, as an alternative to encfs and mcrypt . There dell'interfacce

graphics to generate GPG keys. For those who use Gnome, seahorse, if you use KDE, kgpg. In this case, use the terminal.

You need to first generate the key with the command:

gpg --gen-key

At this point we answer the questions that appear on the 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

display a message like this:

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

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

Encrypt:

gpg-e-r edmond test.txt

or alternatively:

gpg --encrypt --recipient edmond prova.txt

Deciphering:

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

oppure:

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

Per ulteriori informazioni, man gpg
