HTTP-Hypertext Transfer Protocol
HTTPS-Hypertext Transfer Protocol Secure.
TLS-Transport Layer Security.
SSL Secure Sockets Layer.
HTTP stands for HyperText Transfer Protocol. It is a set of rules to send and receive text-based messages. Computers work in a language of 1’s and 0’s, i.e., “binary language.” Therefore, a set of 1’s and 0’s can be a word.
HyperText Transfer Protocol Secure (HTTPS) is the secure version of HTTP, the protocol over which data is sent between your browser and your connected website. It means the communication between your web application and the website is encrypted.
LS stands for Transport Layer Security. TLS is the protocol that provides authentication, privacy, and data integrity between two communicating computer applications. When data has to be securely exchanged by web applications over the network, it is the most likely the deployed security protocol. Applications can include web browsing sessions, file transfers, VPN connections, remote desktop sessions, and voice over IP (VOIP).
SSL stands for Secure Sockets Layer. SSL is a secure protocol developed for sending information securely over the internet. Many websites use SSL for secure areas of their sites, like user account pages and online checkout. Usually, when you are asked to “log in” on a website, the resulting page is secured by SSL creating essentially a secure session.
