The difference between HTTP and HTTPS

"what is the difference between Http and Https?" "

HTTP is the HTTP protocol that runs on top of TCP . All transmitted content is plaintext, and neither the client nor the server can verify the identity of the other.

HTTP is a Hypertext Transfer Protocol, the information is plaintext transmission, unsafe;

The HTTP connection is simple and stateless.

HTTPS is HTTP running on SSL /TLS , andSSL/TLS is running on TCP above. All transmitted content is encrypted and encrypted with symmetric encryption, but the symmetric encryption key is symmetric encrypted with the server-side certificate. In addition, the client can verify the identity of the server side, and if client authentication is configured, the server side can also verify the identity of the client.

The HTTPS protocol requires a certificate to be applied to the CA , and the general free certificate is very small and requires a fee.

HTTPS is an SSL Encrypted transport protocol with security.

HTTPS protocol is a Network protocol built by Ssl+http protocol which can encrypt transmission and authentication, and is more secure than HTTP protocol.

HTTP and https are completely different ways of connecting, and the ports used are not the same (http80,https443) .
