在.NET中简单的rsa加密/解密？

using System;
using System.Security.Cryptography;

public class RSAEncryption
{
    public static void Main(string[] args)
    {
        string plainText = "Hello, World!";
        string encryptedText = Encrypt(plainText);
        string decryptedText = Decrypt(encryptedText);

        Console.WriteLine("Original text: " + plainText);
        Console.WriteLine("Encrypted text: " + encryptedText);
        Console.WriteLine("Decrypted text: " + decryptedText);
    }

    public static string Encrypt(string text)
    {
        RSACryptoServiceProvider rsa = new RSACryptoServiceProvider();
        byte[] encryptedBytes = rsa.Encrypt(System.Text.Encoding.UTF8.GetBytes(text), true);
        return Convert.ToBase64String(encryptedBytes);
    }

    public static string Decrypt(string encryptedText)
    {
        RSACryptoServiceProvider rsa = new RSACryptoServiceProvider();
        byte[] decryptedBytes = rsa.Decrypt(Convert.FromBase64String(encryptedText), true);
        return System.Text.Encoding.UTF8.GetString(decryptedBytes);
    }
}
