The difference between HTTP and HTTPS

1. HTTPS is added to the SSL layer, and the encryption process is as follows:

• The server returns the public key;
• The client generates a random private key by itself, encrypts it with the public key, and sends the encrypted private key;
• The client communicates with the server through the encrypted private key.

2. The difference between HTTP and HTTPS:

• HTTPS is more secure, but not absolutely secure, and most of the time it is powerless in the face of malicious attacks;
• HTTPS requires money to apply for a certificate;
• HTTPS connections are more time-consuming and have problems with caching;
