What is the difference between http and https

http : Hypertext Transfer Protocol  is a system for transmitting and receiving information across the Internet. Http serves as a request and response procedure that all agents on the Internet follow so that information can be rapidly, easily, and accurately disseminated between servers, which hold information, and clients, who are trying to access it. Http is commonly used to access html  pages, but other resources can be utilized as well through http. In many cases, clients may be exchanging confidential information with a server, which needs to be secured in order to prevent unauthorized access. For this reason, https, or secure http, was developed by Netscape corporation  to allow authorization and secured transactions.In many ways, https is identical to http, because it follows the same basic protocols.


There are some primary differences between http and https, however, beginning with the default port, which is 80 for http and 443 for https. 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. 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.

when we using https system use encrypting methods to connect to the server .
