Encryption and Decryption Overview

Encryption is the process of converting plaintext (readable data) into ciphertext (unreadable data) using an algorithm and a key. This ensures that only authorized parties can access the original data.

Decryption is the reverse process, where ciphertext is converted back into plaintext using the same or a corresponding key.

Effortless.Net.Encryption in .NET

Effortless.Net.Encryption is a library that simplifies encryption and decryption in .NET applications. It supports various encryption algorithms like AES, RSA, and more.

Step-by-Step Guide to Using Effortless.Net.Encryption

1. Install the Library

First, install the Effortless.Net.Encryption library via NuGet Package Manager:

Install-Package Effortless.Net.Encryption

---

2. Choose an Encryption Algorithm

Effortless.Net.Encryption supports multiple algorithms. For this example, we'll use AES (symmetric encryption).

3. Encrypt Data

Here’s how to encrypt data using AES:

using Effortless.Net.Encryption;
using System;

class Program
{
    static void Main()
    {
        // Define the plaintext and password
        string plainText = "Hello, World!";
        string password = "MySecretPassword";

        // Generate a random salt (optional but recommended)
        byte[] salt = Bytes.GenerateSalt();

        // Encrypt the data
        byte[] encryptedBytes = AES.Encrypt(plainText, password, salt);

        // Convert encrypted bytes to Base64 for easy storage/transmission
        string encryptedText = Convert.ToBase64String(encryptedBytes);

        Console.WriteLine("Encrypted Text: " + encryptedText);
    }
}

---

4. Decrypt Data

To decrypt the data, use the same password and salt:

using Effortless.Net.Encryption;
using System;

class Program
{
    static void Main()
    {
        // Encrypted text (from previous step)
        string encryptedText = "YourEncryptedBase64StringHere";
        string password = "MySecretPassword";
        byte[] salt = Bytes.GenerateSalt(); // Use the same salt used for encryption

        // Convert Base64 string back to bytes
        byte[] encryptedBytes = Convert.FromBase64String(encryptedText);

        // Decrypt the data
        string decryptedText = AES.Decrypt(encryptedBytes, password, salt);

        Console.WriteLine("Decrypted Text: " + decryptedText);
    }
}

---

5. Key Points

• Password: Use a strong password for encryption.

• Salt: A random salt adds an extra layer of security. Always use the same salt for encryption and decryption.

• Base64 Encoding: Encrypted data is in byte format, so it’s often converted to Base64 for easier handling.

---

Summary

• Encryption: Converts plaintext to ciphertext for security.

• Decryption: Converts ciphertext back to plaintext.

• Effortless.Net.Encryption: Simplifies encryption/decryption in .NET.

• Steps:

  1. Install the library.

  2. Choose an algorithm (e.g., AES).

  3. Encrypt data using a password and salt.

  4. Decrypt data using the same password and salt.

This library makes encryption and decryption straightforward, even for beginners!
