Encryption and Decryption Windows form app project

Question

Create a Windows Form App project containing the following elements:

1- PlainTextBox

2- CipherComboBox: This involves the following options (SimpleCipher, Caesar'sRemoval, CasesarCipher, RSA Cipher, Vigenere Cipher, UUID Cipher, and Playfair Cipher)

3- KeyTextBox

4- EncryptedTextBox

5- DecryptedTextBox

6- EncryptButton

7- DecryptButton. Based on the previous form elements and the following scenario, write the code to create the Windows Form App project:

Scenario:

The user types the text to be encrypted in the PlainTextBox, then selects the encryption algorithm type according to which the text will be encrypted from the CipherComboBox. After selecting the text, he enters the encryption key in the KeyTextBox. When the EncryptButton button is clicked, the entered text is encrypted using the selected algorithm and the entered key and assigned to the EncryptedTextBox. Then, if the DecryptButton button is clicked, the text is encrypted using the selected algorithm and the entered key. Take the encrypted text from the EncryptedTextBox, decrypt it using the same algorithm you chose, and assign the re-encrypted text to the DecryptedTextBox.

Try to write code that is compatible with the .Net9 version.

Creating an Encryption and Decryption Windows form app project involves integrating various elements to allow users to encrypt and decrypt text using different algorithms. Below is a sample code snippet that showcases the basic structure of such a project in .NET 3.0 compatible syntax: using System; using System.Windows.Forms; namespace EncryptionDecryptionApp { public partial class MainForm : Form { public MainForm() { InitializeComponent(); } private void EncryptButton_Click(object sender, EventArgs e) { string plainText = PlainTextBox.Text; string selectedCipher = CipherComboBox.Text; string key = KeyTextBox.Text; string encryptedText = EncryptText(plainText, selectedCipher, key); EncryptedTextBox.Text = encryptedText; } private void DecryptButton_Click(object sender, EventArgs e) { string encryptedText = EncryptedTextBox.Text; string selectedCipher = CipherComboBox.Text; string key = KeyTextBox.Text; string decryptedText = DecryptText(encryptedText, selectedCipher, key); DecryptedTextBox.Text = decryptedText; } private string EncryptText(string text, string cipher, string key) { switch (cipher) { case "SimpleCipher": // Implement SimpleCipher encryption break; case "Caesar'sRemoval": // Implement Caesar'sRemoval encryption break; case "CasesarCipher": // Implement CasesarCipher encryption break; case "RSA Cipher": // Implement RSA Cipher encryption break; case "Vigenere Cipher": // Implement Vigenere Cipher encryption break; case "UUID Cipher": // Implement UUID Cipher encryption break; case "Playfair Cipher": // Implement Playfair Cipher encryption break; default: // Handle unknown cipher break; } // Placeholder return to avoid compilation errors return string.Empty; } private string DecryptText(string text, string cipher, string key) { // Implement decryption logic based on the selected cipher and key // Placeholder return to avoid compilation errors return string.Empty; } } } This code snippet provides a foundation for handling encryption and decryption functionality within a Windows Form application. Remember to replace the placeholder encryption and decryption logic with appropriate algorithms based on the selected cipher method. Feel free to reach out with any further questions or if you require more detailed explanations on specific encryption or decryption algorithms!
