如何实现PHP AES RSA加密算法与C#和Java的互通？

<?php

// 包含加密函数
include 'encryption_functions.php';

// 设置加密服务端点
$endpoint = 'http://localhost:8080/encrypt';

// 创建加密请求
$request = array(
    'data' => '要加密的数据'
);

// 发送加密请求
$response = file_get_contents($endpoint, false, stream_context_create(array(
    'http' => array(
        'method' => 'post',
        'header' => 'content-type: application/json',
        'content' => json_encode($request)
    )
)));

// 处理加密响应
$result = json_decode($response, true);
if ($result['success']) {
    echo '加密成功：' . $result['data'];
} else {
    echo '加密失败：' . $result['message'];
}

?>

using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;
using System.Threading.Tasks;

namespace CSharpClient
{
    public class Program
    {
        static async Task Main(string[] args)
        {
            // 创建 HTTP 客户端
            var client = new HttpClient();

            // 设置请求头
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

            // 创建加密请求
            var request = new StringContent(JsonConvert.SerializeObject(new { data = "要加密的数据" }), Encoding.UTF8, "application/json");

            // 发送加密请求
            var response = await client.PostAsync("http://localhost:8080/encrypt", request);

            // 处理加密响应
            if (response.IsSuccessStatusCode)
            {
                var result = JsonConvert.DeserializeObject<EncryptionResult>(await response.Content.ReadAsStringAsync());
                Console.WriteLine("加密成功：" + result.Data);
            }
            else
            {
                Console.WriteLine("加密失败：" + await response.Content.ReadAsStringAsync());
            }
        }

        class EncryptionResult
        {
            public bool Success { get; set; }
            public string Data { get; set; }
        }
    }
}
