Difference Between http and https


HTTP (Hypertext Transfer Protocol)
HTTP (Hypertext Transfer Protocol) is a protocol used by WWW (World Wide Web). HTTP defines how a message can be formatted and sent from server to client. HTTP also controls what actions to be taken by web servers and web browsers in response to commands in this HTTP protocol. The problem with HTTP is that communication is not fully secure. Information we send to websites such as contact information can be easily retrieved by third parties. For example, it is not advisable to transact on the Internet and banking affairs, as the packets sent using this protocol are not encrypted, so they are considered less secure.


A session on HTTP is a sequence of request transactions and a network response by using the HTTP protocol. An HTTP client will start a request. The client will open a Transmission Control Protocol (TCP) connection to a specified port on a host (usually port 80 or 8080) server listening on port 80 will wait for client request messages. Upon receiving the request, the server sends the status line, such as HTTP / 1.1 200 OK, and messages to be requested, messages to be requested, error messages or other information.


HTTPS (Hypertext Transfer Protocol Secure)

HTTPS (Hypertext Transfer Protocol Secure) is more secure than HTTP. This protocol is covered by SSL / TLS (Secured Socket Layer / Transport Layer Security) as a security measure and serves to authenticate the website so that we can know that the website will perform data encryption. HTTP protocol incorporated in the Application layer of the OSI Layer. Tasks and functions are the same as HTTP but the security level of the HTTPS protocol is more secure in communications or transactions between web browsers and web servers becomes more secure. With this protocol, transactions between web browsers and web servers must go through an authentication and encryption process (such as registration or sign in) of data or messages to be sent.


Differences HTTP and HTTPS

The main difference between http and https, starting with the default port, the 80 for http and 443 for https. Http works with normal interaction transmission, while https through encrypted system. So in theory, information can not be accessed by parties other than clients and servers. There are two common types of encryption layers, namely Transport Layer Security (TLS) and Secure Socket Layer (SSL), where both encode the required data records.


Advantages change HTTP to HTTPS


To secure communication between browser and web server. How can? The following short illustration will answer: When you access a web server that uses the HTTPS protocol, the page sent to you has been encrypted by this protocol. And all the information you send to the server (registration, identity, pin number, payment transfer) will be encrypted as well so no one can steal your data when the transaction is in progress. So your data transactions more secure. HTTPS protocol can be found on banking sites, ecommerce, registration form, etc. Because in this area of business is very vulnerable to theft of data by third parties. That's why you need an SSL certificate.

Quantization of Image Data Implementation in C#

Image
Introduction  This time we will share how to create an application to change the threshold value from black-and-white to the average value of the gray degree of all points and add textBox so that the user can change the threshold value according to the user's wishes. Besides that we also will add textBox to input quantization value. So the user can change the quantization as desired. Application Screenshoot A black-and-white image is an image that contains only black or white. Black is valued 0 and white is valued 255. To make the picture in black and white, the original color will be gray degree and each pixel will be compared with its threshold value. Normally, the black-and-white degree image has a 128 threshold value, so if the color value is less than 128, then the color is changed to 0 (black), and which is greater than or equal to 128 will be converted to 255 (white). Consider the example image below. Figure 1. The original image is predominantly dark When vi

Computer Graphics Project "Planet Orbit" Source Code with Glut OpenGL

Image
Hello there !!!  This time I will post a project in the past. It is about rotation and applied to make earth orbital with moon and sun. As reminder, for you who haven’t install glut you can download it in here and follow the instruction I uploaded too. You can download this orbital project in here too. The image above is the result of orbital project. Here is the source code for this project. #include <windows.h> #include <stdlib.h> #include <GL/glut.h> #include <math.h> void myinit() { glClearColor(0.0, 0.0, 0.0, 1.0); glColor3f(1.0, 0.0, 0.0); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(-400.0, 400.0, -400.0, 400.0,-400.0,400.0); glMatrixMode(GL_MODELVIEW); glShadeModel(GL_FLAT); glEnable(GL_DEPTH_TEST); } float putaransatu, putarandua = 0; typedef struct{ float x,y; } point2D_t; void drawDot(int x,int y){ glBegin(GL_POINTS); glVertex2i(x,y); glEnd(); } /*void bintang(void) { static int tick=0; static poi

Computer Graphics Project "MINION" Source Code with Glut OpenGL

Image
Hello !!! This time I post about computer graphics again. And yes, I will share a project which mainly used rotation and a little bit morphing. You can download this project here ( Download here to download glut and follow the instruction ) .The character used in this project is well known. Well here’s the depiction of this project. Minion !!! The eyes will rotate. And it’s smile will move up and down which give you a creepy smile hahaha.  So here’s the source code for this project : #include <stdio.h> #include <math.h> #include <GL/glut.h> #ifndef M_PI #define M_PI 3.141592653589793 #endif typedef struct { float x; float y; } point2D_t; typedef struct { float r; float g; float b; } color_t; ////////////// OpenGL drawShape Functions ver 1 ///////////////// void setColor(float red,float green,float blue) { glColor3f(red, green, blue); } void setColor(color_t col) { glColor3f(col.r, col.g, col.b); } void drawDot(float x,float y) { glB
