En ligne de commande¶

Installation de l'outil

sudo apt-get install gnupg

Génération de la clef

gpg --full-generate-key

Il y aura un premier lot de choix à réaliser (type d'utilisation, degré de chiffrement, durée de validité)

gpg: keyring /home/user/.gnupg/secring.gpg' created
gpg: keyring/home/user/.gnupg/pubring.gpg' created
Please select what kind of key you want:
(1) RSA and RSA (default)
(2) DSA and Elgamal
(3) DSA (sign only)
(4) RSA (sign only)
Your selection? 1
RSA keys may be between 1024 and 4096 bits long.
What keysize do you want? (2048) 4096
Requested keysize is 4096 bits
Please specify how long the key should be valid.
0 = key does not expire
= key expires in n days
w = key expires in n weeks
m = key expires in n months
y = key expires in n years
Key is valid for? (0) 3y
Key expires at Tue 11 May 2019 12:53:08 AM EDT
Is this correct? (y/N) y

Ensuite viendront d'autres questions concernant votre identité puis le mot de passe

You need a user ID to identify your key; the software constructs the user ID
from the Real Name, Comment and Email Address in this form:
"Heinrich Heine (Der Dichter) heinrichh@duesseldorf.de"
Real name: Test User
Email address: test@example.org
Comment:
You selected this USER-ID:
"Test User test@example.org"
Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? o
You need a Passphrase to protect your secret key.
passphrase not correctly repeated; try again.
We need to generate a lot of random bytes. It is 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.
..........+++++

A ce moment-là c'est une bonne idée de lancer une vidéo, faire des trucs sur le pc
(note : il existe un utilitaire qui crée de l'entropie tout seul mais 'jme rapelle plus de son nom)

gpg: /home/user/.gnupg/trustdb.gpg: trustdb created
gpg: key 23955501 marked as ultimately trusted
public and secret key created and signed.

A ce moment-là les clefs sont crées (probablement dans ~/.gnupg
