The difference between http and HTTPS and the introduction of SSL
Overview: HTTPS is just a secure version of HTTP. It's just a link to an HTTPS encrypted trust, which requires a trust institution to issue a trusted certificate.

1. About the difference of ports: http: 80 port, HTTPS:443 port.

2. The difference between data transmission: clear text transmission of HTTP data and encrypted transmission of HTTPS data.

3. Identification of true and false websites: HTTP is easy to be copied, and HTTPS websites must use real-name OV or EV certificates, which are very strict, especially EV certificates. The address bar will directly display the name, such as the websites of major banks.

4. Application transmission: HTTP works in the application layer and HTTPS works in the transport layer.

5, address protocol difference:

At the beginning of http:// (it is not safe to display a question mark in the case of a browser)

Https:// beginning (the browser displays the security, small green lock icon)

6. protocol threshold: HTTP does not need a certificate, and HTTPS needs an SSL certificate issued by Gworg.

7. With regard to hijacking:

HTTP can be easily hijacked, open a webpage or even jump directly to another website.

HTTPS encryption is secure, not hijacked, and the transaction transmission data is encrypted.

SSL certificate is a digital certificate, which is issued by a trusted digital certificate authority CA after verifying the identity of the server. It has server authentication and data transmission encryption functions.
