TLS uses public-key cryptography only to agree on a shared secret, then encrypts the actual data with a symmetric cipher such as AES. Why?
TLS n'utilise la cryptographie à clé publique que pour convenir d'un secret partagé, puis chiffre les données elles-mêmes avec un algorithme symétrique comme AES. Pourquoi ?
Answers
ASymmetric encryption is far faster for bulk dataLe chiffrement symétrique est bien plus rapide pour de gros volumes
BPublic-key methods are unable to encrypt any text at allLes méthodes à clé publique ne peuvent chiffrer aucun texte
CAES works only over TLSAES ne fonctionne qu'à travers TLS
DIt avoids the need for certificatesCela évite d'avoir besoin de certificats
