What is SSL and how does it relate to HTTPS?
333
The S in "HTTPS" stands for "secure." HTTPS is just HTTP with SSL/TLS. A website with an HTTPS address has a legitimate SSL certificate issued by a certificate authority, and traffic to and from that website is authenticated and encrypted with the SSL/TLS protocol.
HTTPS and SSL are similar things but not the same. HTTPS basically a standard Internet protocol that makes the online data to be encrypted and is a more advanced and secure version of the HTTP protocol. SSL is a part of the HTTPS protocol that performs the encryption of the data.
Secure Sockets Layer (SSL) is a security protocol that provides privacy, authentication, and integrity to Internet communications.
SSL uses port number 443, encrypting data exchanged between the browser and the server and authenticating the user. Therefore, when the communications between the web browser and server need to be secure, the browser automatically switches to SSL — that is, as long as the server has an SSL certificate installed.
SSL is the secure socket layer, a cryptographic protocol to encrypt network traffic. The most recent version of SSL is version 3, which fixed some known issues in SSLv2. HTTPS is HTTP over SSL... or HTTP over TLS.
TLS (Transport Layer Security) is the successor to SSLv3 and is largely replacing SSLv3 as the default HTTPS protocol in web browsers and servers.
As a side note, HTTPS usually listens on port 443, rather than port 80.
