What is HTTPS

1. In many ways, https is identical to http, because it follows the same basic protocols.
2. Use of https in a URI scheme rather than http indicates that an encryptedconnection is desired.
3. Https works by transmitting normal http interactions through an encrypted system, so that in theory, the information cannot be accessed by any party other than the client and end server
4. Https uses 443 port by default it can be changed using httpd.conf on apache server similar to port 80 on apache
5. There are two common types of encryption layers: Transport Layer Security (TLS) and Secure Sockets Layer (SSL), both of which encode the data records being exchanged.
6. Concept how https works : When using an https connection, the server responds to the initial connection by offering a list of encryption methods it supports. In response, the client selects a connection method, and the client and server exchange certificates to authenticate their identities. After this is done, both parties exchange the encrypted information after ensuring that both are using the same key, and the connection is closed
7. In order to host https connections, a server must have a public key certificate, which embeds key information with a verification of the key owner's identity
8. Most certificates are verified by a third party like goDaddy.
9. Https is used in many situations, such as banking and where information security plays more vital role
