What encryption algorithm does HTTPS use?

HTTPS uses Transport Layer Security (TLS)/SSL protocol to encrypt communication between the client and the server. This protocol uses asymmetric encryption to encrypt those communications, which creates private and public keys to secure the communication.

Does HTTPS use RSA or Diffie Hellman?

Is D-H always used in HTTPS? The answer is NO. In practice, Diffie–Hellman is not used with RSA being the dominant public key algorithm. The first element of the CipherSuite parameter (see the Handshake Protocol in Action figure above) is the key exchange method.

How does encryption work in HTTPS?

How does HTTPS work? HTTPS uses an encryption protocol to encrypt communications. The protocol is called Transport Layer Security (TLS), although formerly it was known as Secure Sockets Layer (SSL). This protocol secures communications by using what's known as an asymmetric public key infrastructure.

Does SSL use AES?

SSL uses symmetric cryptography using the session key after the initial handshake is done. The most widely used symmetric algorithms are AES-128, AES-192 and AES-256.
