What is the difference between Http and Https?

The hypertext transfer protocol (http) is a system for transmitting and receiving information over the Internet. Http works as a request and response procedure that all Internet agents follow so that information can be disseminated quickly, easily and accurately between the servers that store the information and the clients that are trying to access it. Http is commonly used to access html pages, but other features can also be used via http. In many cases, clients may be exchanging confidential information with a server, which needs to be secured to prevent unauthorized access. For this reason, https, or secure http , was developed by Netscape Corporation to allow authorization and secure transactions.

Https or secure http.

In many ways, https is identical to http, because it follows the same basic protocols. The http or https client, like a web browser, establishes a connection to a server on a standard port. When a server receives a request, it returns a status and a message, which can contain the requested information or indicate an error if part of the process does not work correctly. Both systems use the same Uniform Resource Identifier (URI) scheme, so resources can be universally identified. Using https in a URI scheme instead of http indicates that an encrypted connection is desired.

Http is not encrypted.

There are some key differences between http and https, however, starting with the default port, which is 80 for http and 443 for https. Https works by passing normal http interactions through an encrypted system, so, in theory, the information cannot be accessed by anyone other than the client and the end server. There are two common types of encryption layers: Transport Layer Security (TLS) and Secure Sockets Layer (SSL), both of which encrypt the data records being exchanged.

When using an https connection, the server responds to the initial connection by offering a list of supported encryption methods. In response, the client selects a connection method and the client and server exchange certificates to authenticate their identities. After doing this, both parties exchange the encrypted information after ensuring they are both using the same key and the connection is closed. To host https connections, a server must have a public key certificate, which embeds key information with a verification of the key owner’s identity. Most certificates are third-party verified so customers can be sure the key is secure.

Https is used in many situations such as login pages for banks, forms, corporate logins and other applications where data needs to be protected. However, if not implemented correctly, https is not foolproof and therefore it is extremely important for end users to be careful when accepting questionable certificates and to be cautious with their personal information when using the internet.
