C# ase加密后Java 可以访问的代码

以下是使用C#进行ASE加密后，Java可以访问的代码示例：

C# 代码（使用ASE加密）：

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

public class AESExample
{
    public static string Encrypt(string plainText, string key, string iv)
    {
        using (Aes aesAlg = Aes.Create())
        {
            aesAlg.Key = Encoding.UTF8.GetBytes(key);
            aesAlg.IV = Encoding.UTF8.GetBytes(iv);

            ICryptoTransform encryptor = aesAlg.CreateEncryptor(aesAlg.Key, aesAlg.IV);

            using (MemoryStream msEncrypt = new MemoryStream())
            {
                using (CryptoStream csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write))
                {
                    using (StreamWriter swEncrypt = new StreamWriter(csEncrypt))
                    {
                        swEncrypt.Write(plainText);
                    }
                    byte[] encryptedBytes = msEncrypt.ToArray();
                    return Convert.ToBase64String(encryptedBytes);
                }
            }
        }
    }
}

Java 代码（解密使用）：

import javax.crypto.*;
import javax.crypto.spec.*;
import java.security.*;
import java.util.Base64;

public class AESExample {
    public static String Decrypt(String cipherText, String key, String iv) throws Exception {
        Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
        SecretKeySpec secretKeySpec = new SecretKeySpec(key.getBytes("UTF-8"), "AES");
        IvParameterSpec ivParameterSpec = new IvParameterSpec(iv.getBytes());
        cipher.init(Cipher.DECRYPT_MODE, secretKeySpec, ivParameterSpec);

        byte[] encryptedBytes = Base64.getDecoder().decode(cipherText);
        byte[] decryptedBytes = cipher.doFinal(encryptedBytes);

        return new String(decryptedBytes);
    }
}

通过将加密后的数据从C#传递到Java，您可以使用上述Java代码进行解密。请确保在使用Java代码之前，将该代码添加到您的Java项目中，并在使用时提供正确的密钥和IV值。
