SSL/TLS certificates use asymmetric cryptography, where a public key embedded in the certificate encrypts data and the server's corresponding private key decrypts it. This public/private key pair is the foundation of HTTPS, enabling secure key exchange and data confidentiality during e-commerce transactions.

Confidential is not a recognized category of cryptographic certificate or encryption type in any standard framework.

Symmetric encryption uses the same shared key for both encryption and decryption and is not what certificates implement - certificates are inherently asymmetric constructs tied to a key pair.

Non-confidential is not a defined certificate or encryption classification in any cryptographic standard.
