This document describes the advantages of HTTPS over HTTP, and the supported certificate types and encryption algorithms.

HTTPS Overview

As an extension of HTTP, HTTPS supports identity verification and encrypted transmission through the SSL protocol. SSL uses HTTPS certificates to verify the server's identity and establish an encrypted transmission channel between the client browser and the server. Compared to HTTP, HTTPS offers the following advantages:
Higher security: HTTPS encrypts the data exchanged between clients and servers to prevent the data from being hijacked, tampered, or listened to.
Increased website credibility: When users access a website over HTTPS, they can verify the website credibility based on its certificate. If the website is trustworthy, a green security identifier is displayed in the browser. This improves the website credibility and prevents users from accessing phishing websites.
Improved website SEO: Search engines prioritize trustworthy websites that support HTTPS. Enabling HTTPS access to a website can improve the website ranking in search engine results.

Differences Between Free and Paid Certificates

EdgeOne provides you with free and paid certificates.
If you want to configure a certificate for the domain of a SME site or personal blog to support access over HTTPS, please configure a free certificate for the domain.
If you want to configure a certificate issued by an authority with higher credibility, or if you already have a self-owned certificate, please configure a self-owned certificate for the domain.
