Remarques

Les noms conviviaux sont des propriétés du magasin de certificats X.509 qui peuvent être définies. Ils sont utilisés pour permettre à un utilisateur d’associer des alias à des certificats afin qu’ils puissent être facilement identifiés.

S’il n’existe aucun nom convivial pour le certificat, une chaîne vide («  ») est retournée.
