陪玩系统源码，为守护系统安全增添更多助力
在开发陪玩系统源码时，可以通过加密、解密算法来提升系统的安全性，比较常见的加密、解密算法类型有：

1、对称加密：速度快，可逆，常见DES，AES等
2、非对称加密：速度慢，可逆，常见RSA等
3、签名算法：唯一，不可逆，常见MD5，SHA，SHA256等

安全数据传输方案

如果陪玩系统源码中需要传输的数据较大，则可以将几类加密、解密算法结合起来使用：
安全的数据传输方案如下：

这里按照 A、B作为交换数据的双方，A向B发送加密数据。
前提，A，B都有自己的RSA公钥和私钥且A，B已经交换过RSA公钥
A，B使用相同的一套加密、解密算法（对称加密DES、非对称加密RSA、签名算法SHA256举例）

A，B使用相同的一套加密、解密算法，可以让A，B使用同一套SDK，SDK包含了标准的对称加密DES、非对称加密RSA、签名算法SHA256的实现；A，B也按照相同的SDK处理加密、解密以及数据传输。

源码

不废话了，下面直接上代码：

业务数据的加密、解密：
接口：

import java.util.Map;

public interface BusinessCryptoService {

    /**
     * 根据key加密数据
     *
     * @param yourPublicKey 对方公钥
     * @param password      密码
     * @param data          数据
     * @return 加密数据
     */
    Map<String, String> encrypt(String yourPublicKey, String publicKey, String privateKey, String password, String data);

    /**
     * 根据key解密数据
     *
     * @param yourPublicKey 对方公钥
     * @param password      加密密码
     * @param data          加密数据
     * @param sign          签名数据
     * @return 解密数据
     */
    Map<String, String> decrypt(String yourPublicKey, String privateKey, String password, String data, String sign);
}
