| - | Générer une clé [[https:// | ||
| - | <code bash> | ||
| - | $ ssh-keygen -t ed25519 | ||
| - | Generating public/ | ||
| - | Enter file in which to save the key (/ | ||
| - | Enter passphrase (empty for no passphrase): | ||
| - | Enter same passphrase again: | ||
| - | Your identification has been saved in / | ||
| - | Your public key has been saved in / | ||
| - | The key fingerprint is: | ||
| - | SHA256: | ||
| - | The key's randomart image is: | ||
| - | +--[ED25519 256]--+ | ||
| - | | oo..o=o@@X | ||

| - | and check to make sure that only the key(s) you wanted were added. | ||
| - | </ | ||

| - | Plus qu'à se connecter, sans rentrer de code cette fois : | ||
| - | <code bash> | ||
| - | simon@localhost: | ||
| - | LOGIN@HOST~$ | ||

| - | |||
| - | ==== Changer la passphrase d'une clé SSH ==== | ||
| - | |||
| - | <code bash> | ||
| - | $ cd .ssh/ | ||
| - | $ ssh-keygen -f id_rsa -p | ||
| - | Enter old passphrase: | ||
| - | Key has comment 'rsa w/o comment' | ||
