JavatoC#加密转换

在Java中使用的加密算法可能与C#中的加密算法不同，因此需要进行转换以使其兼容。

示例代码：

Java代码：

import javax.crypto.Cipher;
import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;
import javax.crypto.spec.SecretKeySpec;
import java.security.Key;

public class JavaEncryption {
    public static void main(String[] args) throws Exception {
        String plainText = "This is a plain text.";
        Key key = generateKey();
        Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
        cipher.init(Cipher.ENCRYPT_MODE, key);
        byte[] encryptedBytes = cipher.doFinal(plainText.getBytes());
        System.out.println("Encrypted text: " + new String(encryptedBytes));
    }

    public static Key generateKey() throws Exception {
        KeyGenerator generator = KeyGenerator.getInstance("AES");
        generator.init(128);
        SecretKey secretKey = generator.generateKey();
        byte[] keyBytes = secretKey.getEncoded();
        return new SecretKeySpec(keyBytes, "AES");
    }
}

转换为C#代码：

using System;
using System.Security.Cryptography;
using System.Text;

class CSharpEncryption {
    static void Main(string[] args) {
        string plainText = "This is a plain text.";
        byte[] keyBytes = GenerateKey();
        byte[] encryptedBytes = Encrypt(plainText, keyBytes);
        Console.WriteLine("Encrypted text: " + Encoding.UTF8.GetString(encryptedBytes));
    }

    static byte[] GenerateKey() {
        AesCryptoServiceProvider provider = new AesCryptoServiceProvider();
        provider.KeySize = 128;
        provider.GenerateKey();
        return provider.Key;
    }

    static byte[] Encrypt(string plainText, byte[] keyBytes) {
        AesCryptoServiceProvider provider = new AesCryptoServiceProvider();
        provider.Key = keyBytes;
        provider.Mode = CipherMode.ECB;
        provider.Padding = PaddingMode.PKCS7;
        ICryptoTransform encryptor = provider.CreateEncryptor();
        byte[] plainBytes = Encoding.UTF8.GetBytes(plainText);
        byte[] encryptedBytes = encryptor.TransformFinalBlock(plainBytes, 0, plainBytes.Length);
        return encryptedBytes;
    }
}
