<para>Cette vérification utilise tout d'abord une expression régulière
pour valider la forme syntaxique de la clé publique

tente de décoder la partie en base64 de la clé pour vérifier qu'il s'agit
bien d'une chaine de caractères dans laquelle on retrouve bien le type de
la clé (<literal>ssh-[type]</literal>).</para>
