J'ai essayé de googler ma question mais je n'ai trouvé aucune réponse qui fonctionne...
J'ai un id_dsa privée, mais j'ai "perdu" ma clé publique.
Lorsque je génère un nouveau fichier public avec ssh-keygen -yf .ssh/id_dsa > .ssh/id_dsa.pub Le logiciel ssh commence à me demander le mot de passe au lieu de la phrase d'authentification.
Cela pourrait être lié à xattr sur ce fichier ? Si oui, je n'ai pas trouvé comment définir un xattr approprié sur id_dsa.pub.
Une idée pour régénérer ma clé publique ? (sauf générer une nouvelle paire de clés ^^)
Merci pour le temps que vous avez passé à me lire ;-)

J'espère que cela vous aidera
