what is SSL and HTTPS is there any major distance?

Simply put, HTTP (HyperText Transfer Protocol) plus SSL (Secure Sockets Layer) or TLS (Transport Layer Security) = HTTPS.

The 'S' in HTTPS just stands for secure.

SSL – or Secure Socket Layer – is a technology that prevents anyone other than the authorized party from looking at your data. SSL turns your “plain text” data into “cipher text” through the process of encryption while the HTTPS (Hyper Text Transfer Protocol Secure) appears in the URL when a website is secured by an SSL certificate
