GUI means the Graphical User Interface applications, that specifically permit the users to directly interact with the computer system using buttons and screens. This includes other special options like graphical icons, and audio indicators, instead of any text-based user interfaces.
Text-based user interfaces are common types of labels and it mainly includes text navigation.
It is a way of designing how you want your system application should behave according to the requirements, using symbols or any kind of visual metaphors.
The GUI is both texts as well as keyboard oriented. Today’s major operating systems work on the GUI. There are notable components that are included and to be included in the GUI.
Some of them are pointers, icons, windows, menus, scroll bars, and intuitive input devices. Any GUI that works is associated with Microsoft Windows, Mac OSX, Chrome OS, GNOME, KDE, and Android.
This small project mainly focuses on enabling the task of encryption decryption in python using the GUI features
Encryption decryption in GUI:
cryptography is the main branch of cyber protection that changes the text of a message so that people who don't know your secret never understand your message.
Today, cryptography is used to protect digital data. It is a division of computer science that focuses on transforming data into formats that cannot be recognized by unauthorized users. An example of basic cryptography is an encrypted message in which letters are replaced with other characters.
Cryptography provides for secure communication in the presence of malicious third parties—known as adversaries. Encryption uses an algorithm and a key to transform an input (i.e., plaintext) into an encrypted output (i.e., ciphertext). This project creates a GUI application to encrypt and decrypt using Python.
The first step is to create a program that will first ask you if you want to encrypt a message or decrypt a message. Then the program should receive a message from the user. If the user chooses an option to encrypt a message, then, the user’s message must be transformed into a proper secret code. Also, if the user chooses to decrypt the message, the program should be able to convert the given secret code into a complete, meaningful text.
The second step is to write another program that rearranges the order of the letters which is there in the user input so that it cannot be understood by anyone. This can be done by even putting the letters in odd positions and even positions. Then we must swap the first 2 letters with the next 2 and so on. The process of encryption to decryption or vice versa can be done by reversing the letters according to the user input. The code uses an infinite loop that will keep asking the user if they want to encrypt or decrypt a message.
We write an event program because the operation of the program depends on the user input. The code uses a dialogue box to get user input and the information box to show the encrypted and decrypted message to the user. The program will finally end at one point, where the user gives input other than encrypt or decrypt.
Benefits of GUI:
Easy to use. Since data is represented by symbols, shapes, and icons
users can easily recognize, classify and navigate options
Easy to communicate.
Visual representation of data is recognized faster than text.
Allows for multitasking.
