What secure protocol is the encryption method associated with HTTPS?

The encryption method associated with HTTPS is SSL (Secure Sockets Layer). HTTPS, which stands for HyperText Transfer Protocol Secure, uses SSL to establish an encrypted connection between a web server and a client’s browser. This encryption is essential for protecting the confidentiality and integrity of data transmitted over the internet.

SSL operates by providing a secure channel that encrypts the data before it gets transmitted, ensuring that any sensitive information, such as login credentials or payment information, is shielded from eavesdropping or tampering. While SSL has been largely succeeded by its successor, TLS (Transport Layer Security), the term SSL is still commonly used to refer to the security technologies behind HTTPS.

The other protocols mentioned serve different purposes. IPSec is primarily used for securing IP communications by authenticating and encrypting each IP packet in a communication session. SSH-2, on the other hand, is a protocol used to securely connect to remote computers, primarily for command-line access and file transfers. MPLS (Multi-Protocol Label Switching) is a technique in networking for speeding up the flow of network traffic and is not directly related to encryption or secure communications like HTTPS.
