Http and Https Difference According to Expert

  HTTP and HTTPS protocol is code language that is familiar to Internet users, because in each of the links that refer to the web site can already be sure to use HTTP and HTTPS. This code also often encountered when we want to browse or open the page certain web. We are asked to type the code at the beginning and end with colons and slashes twin when we do browsing web pages as desired.

HTTP (Hypertext Transfer Protocol)

Hypertext Transfer Protocol (HTTP) is a network protocol layer applications that are used for distributed information systems, collaborative, and use hypermedia lot in utilize the resources associated with the link called hypertext documents that form the World Wide Web. In 1990 by the English physicist named Tim Berners Lee. Http is a protocol that provides communication between network command, which is a network of communication between the client computer with a web server. In this communication, computer client will make request by typing the address or the website that you want to access. While server processes requests based on the protocol code meals. HTTP is called a stateless protocol because each command is executed independently, without any knowledge of the commands that come previous. This is the main reason that it is difficult to implement a website that react intelligently to user input.

Hypertext Transfer Protocol Secure (HTTPS)

Hypertext Transfer Protocol Secure (HTTPS) have the same meaning such as HTTP. but HTTPS has advantages in the field of functions security (secure). HTTPS invented by Netscape Communications Corporation. HTTPS uses Secure Socket Layer (SSL) or Transport Layer Security (TLS) as a sublayer under the application layer Regular HTTP.

HTTP encryption and description of the page requested by the user and pages that are returned by the web server. Both protocols that provide adequate protection from attacks tapper. In general, use the HTTPS port is port 443. The level of security depends on the correctness of implemented on a web browser and server software and supported by the actual encryption algorithm. Therefore the use of HTTPS web pages, and URLs used starts with 'https: //www.facebook.com/' Https can guarantee security in the Authentication server browser which allows users to have confidence that they talking directly with the application server server.Https also able to maintain data confidentiality and data integrity.

The Main Difference HTTP and HTTPS

Some major differences between http and https, starting 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 in theory, the information can not be accessed by the other than the end client and the server. There are two general types of layers Encryption: Transport Layer Security "TLS" and Secure Socket Layer "SSL", both of which encode the data records are exchanged.

How it Works?

Https instead of a separate protocol, but refers to the combination sockets layer of normal HTTP interaction encrypted via SSL Secure or Transport Layer Security (TLS) transport mechanism. This ensures reasonable protection from eavesdroppers and as long as it is properly implemented and the authority level of conduct they work well against attacks.

The default TCP port https: URL is 443 for unsecured HTTP, the default is 80. To set up a web-server for https connection as an administrator and receiver must make a certificate public key to the web server.

This certificate can be created for Linux based servers with tools such as Open SSL or SuSE gensslcert. Web browsers in general distributes the process of signing a major certificate authorities, then they will be able to verify the certificate has been signed.

When using a https connection, the server responds with the initial connection offering a list of encryption methods support. Responding to client select a connection method, and the client and server certificate authentication exchange for their identity. Once this is done, the second parties exchanging encrypted information after ensuring that both use the same key, and the connection is closed. To host https connection, the server must have a certificate public key, which embeds key information to verify key owner's identity. Most certificates are verified by party the third so that the client believes that the key is secure.

Gain Changing HTTP to HTTPS

To secure the communication between the browser with the web server. When you access a web server that uses the HTTPS protocol, the page is sent to you first encrypted by this protocol. And all the information that you send to the server registration, identification, pin numbers, transfer payments will also encrypted so no one can hear (eavesdropping) data when a transaction is in progress. So the data you become more secure transactions. HTTPS protocol can be found on the websites of banking, e-commerce, application forms, etc. Because in area this business is prone to interception by third parties. For that you require SSL certificate. Internet connection using HTTPS is more secure than using HTTP. For that many banks are building services their online using HTTPS format. It aims to ensure the safety of customers when conducting transactions online. Not only online transactions, government or institution also protect the security of documents the importance of using HTTPS. HTTP is not limited to use with TCP / IP, although HTTP is an application protocol TCP / IP is the most popular on the Internet. Indeed HTTP can be implemented in on other protocols via the Internet or via other networks.

Understand The URL (Uniform Resource Locator)

is a series of characters according to a certain standard format, which is used to indicate the address of a source such as documents and pictures on the Internet. URL was first created by Tim Berners-Lee in 1991 that the document author can a reference link to the World Wide Web. Since 1994, the concept has evolved into the term URL Uniform Resource Identifier (URI), which is more common. Function, Definition, and URL history You can see here. FTP (File Transfer Protocol) is a protocol used for exchange files in a network using TCP instead of UDP.

Two things are important in FTP Server and FTP Client.

1.FTP server is a server that is running software that works to provide services to exchange files in which the server is always ready to provide FTP services if a request is received (request) from the FTP client.

2.FTP client is a computer requesting a connection to an FTP server for the purpose of exchanging files. Once connected to an FTP server, then the client can download, upload, rename, delete, etc. In accordance with the permission granted by the FTP server. So the conclusion of the FTP server is as follows:

1. For the purpose of sharing data.

2. To provide a remote computer indirect or implicit.

3. To provide storage for users.

4. To provide reliable data transfer and efficient, maybe just this that I can write, actually there are many differences between the http and https, waiting for the next article, have a nice day.
