J'ai lu beaucoup de choses sur les certificats SSL et j'ai encore une chose à clarifier. Quelle est la différence bewteen un certificat SSL et une clé publique/clé privée?Certificat SSL: clé publique ou clé privée?
Un certificat (ou contient-il) une clé publique? Clé privée? tous les deux? ou cela n'a rien à voir avec l'un ou l'autre?
J'ai trouvé un exemple de certificat. Je peux voir la clé publique, mais pour la partie du certificat, je ne sais pas si une partie de la clé privée a déjà été intégré:
