How can I encrypt my database in C#?

You can use the AesCryptoServiceProvider class in C# to encrypt your database. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

using System;
using System.IO;
using System.Security.Cryptography;

public class EncryptionExample
{
    public static void Main()
    {
        string original = "Sensitive data";
        using (Aes aes = Aes.Create())
        {
            aes.Key = Convert.FromBase64String("your-base64-key");
            aes.IV = Convert.FromBase64String("your-base64-iv");

            // Encrypt
            ICryptoTransform encryptor = aes.CreateEncryptor(aes.Key, aes.IV);
            using (MemoryStream msEncrypt = new MemoryStream())
            {
                using (CryptoStream csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write))
                {
                    using (StreamWriter swEncrypt = new StreamWriter(csEncrypt))
                    {
                        swEncrypt.Write(original);
                    }
                    byte[] encrypted = msEncrypt.ToArray();
                    Console.WriteLine(Convert.ToBase64String(encrypted));
                }
            }
        }
    }
}

Make sure to replace "your-base64-key" and "your-base64-iv" with your actual key and IV.

What should I do to securely store the encryption key?

You should store the encryption key in a secure location, such as Azure Key Vault or AWS Secrets Manager, rather than hardcoding it in your application.
