Difference between HTTPS and SSL
Solution 1:
The explanation of SSL that you've found is wrong.
SSL (Secure Socket Layer) or TLS (Transport Layer Security) works on top of the transport layer, in your examples TCP. TLS can be used for more or less any protocol, HTTPS is just one common instance of it.
HTTP is an application layer protocol.
In regular, non-encrypted HTTP, the protocol stack can look like this:
- HTTP
- TCP
- IP
- Ethernet
When using HTTPS, the stack looks like this:
- HTTP
- TLS (SSL)
- TCP
- IP
- Ethernet
Solution 2:
HTTPS runs over SSL (as it's name suggests, HTTP-over-SSL), not SSL over HTTP. First SSL session is established, then all HTTP data are wrapped into secured SSL packets before sending and after receiving.
Solution 3:
SSL (Secure Sockets Layer) is a standard security technology to create an encrypted link between a server and a client. This link ensures that all data passed between the server and the client remain private and secure. It was designed to support protocols such as FTP, HTTP, TELNET.
Hypertext Transfer Protocol Secure (HTTPS) or “HTTP Secure,” is an application specific implementation that is a combination of the Hypertext Transfer Protocol (HTTP) with the SSL/TLS. HTTPS is used to provide encrypted communication and secure identification of a server, so that no middle man can intercept the data easily.
As everything in HTTP is in plain text (or encoded) , it is used with SSL/TLS to encrypt it.
