rsa互通密钥对生成及互通加解密(c#,java,php)

摘要

在数据安全上rsa起着非常大的作用，特别是数据网络通讯的安全上。当异构系统在数据网络通讯上对安全性有所要求时，rsa将作为其中的一种选择，此时rsa的互通性就显得尤为重要了。

本文参考网络资料，提供了rsa互通性的一种可行的解决方案(c#,java,php),而这种互通性是在一定的局限性上达成的，比如密钥是1024位的(更高位没试过，应该也可行），基于PKCS1填充方式。

所编写的代码有一部分使用了硬编码，同时注重了功能的实现，在类结构设计上关注不多，有需要的可自行修改重构。

相关的程序集或包或代码请详见本文末尾附件。

一、生成互通密钥对

重点参考了Jeffrey Walton（http://www.codeproject.com/Articles/25487/Cryptographic-Interoperability-Keys）

1.c#

using Cn.Ubingo.Security.RSA.Core;

using Cn.Ubingo.Security.RSA.Key;

//生成公私钥对

KeyPair keyPair = KeyGenerator.GenerateKeyPair();

//转换成不同的格式

KeyPair asnKeyPair = keyPair.ToASNKeyPair();

KeyPair xmlKeyPair = asnKeyPair.ToXMLKeyPair();

KeyPair pemKeyPair = xmlKeyPair.ToPEMKeyPair();

//获取公私钥，以xml格式的为例

string privateKey = xmlKeyPair.PrivateKey;

string publicKey = xmlKeyPair.PublicKey;

2.java

import cn.ubingo.security.rsa.core.*;

import cn.ubingo.security.rsa.key.*;

//生成密钥对

KeyPair keyPair = KeyGenerator.generateKeyPair();

//转换成不同的格式

KeyPair asnKeyPair = keyPair.toASNKeyPair();

KeyPair xmlKeyPair = asnKeyPair.toXMLKeyPair();

KeyPair pemKeyPair = xmlKeyPair.toPEMKeyPair();

//获取公私钥，以asn格式的为例

String publicKey = asnKeyPair.getPublicKey();

String privateKey = asnKeyPair.getPrivateKey();

4.密钥互通性

各种格式的密钥都可以通过KeyPair类的c#:To*KeyPair()或java:to*KeyPair()方法相互进行转换，无门槛，无障碍。

c#

//转换成不同的格式

KeyPair asnKeyPair = keyPair.ToASNKeyPair();

KeyPair xmlKeyPair = asnKeyPair.ToXMLKeyPair();

KeyPair pemKeyPair = xmlKeyPair.ToPEMKeyPair();

java

//转换成不同的格式

KeyPair asnKeyPair = keyPair.toASNKeyPair();

KeyPair xmlKeyPair = asnKeyPair.toXMLKeyPair();

KeyPair pemKeyPair = xmlKeyPair.toPEMKeyPair();

二、互通加解密

基于三种语言环境都支持的RSA PKCS1填充方式的算法，实现加解密互通

KeyWorker的c#:Encrypt,Decrypt或java:encrypt,decrypt或php:encrypt,decrypt方法实现加解密的功能

1.c#

using Cn.Ubingo.Security.RSA.Core;

using Cn.Ubingo.Security.RSA.Data;

//加解密

//XML

KeyWorker privateWorker = new KeyWorker(privateKey, KeyFormat.XML);

KeyWorker publicWorker = new KeyWorker(publicKey, KeyFormat.XML);

Console.WriteLine(privateWorker.Decrypt(publicWorker.Encrypt("你好！世界")));

Console.WriteLine(publicWorker.Decrypt(privateWorker.Encrypt("你好！中国")));

//ASN

privateWorker = new KeyWorker(asnKeyPair.PrivateKey, KeyFormat.ASN);

publicWorker = new KeyWorker(asnKeyPair.PublicKey, KeyFormat.ASN);

Console.WriteLine(privateWorker.Decrypt(publicWorker.Encrypt("你好！世界")));

Console.WriteLine(publicWorker.Decrypt(privateWorker.Encrypt("你好！中国")));

//PEM

privateWorker = new KeyWorker(pemKeyPair.PrivateKey, KeyFormat.PEM);

publicWorker = new KeyWorker(pemKeyPair.PublicKey, KeyFormat.PEM);

Console.WriteLine(privateWorker.Decrypt(publicWorker.Encrypt("你好！世界")));

Console.WriteLine(publicWorker.Decrypt(privateWorker.Encrypt("你好！中国")));

2.java

import cn.ubingo.security.rsa.core.*;

import cn.ubingo.security.rsa.data.*;

//ASN

KeyWorker privateWorker = new KeyWorker(privateKey, KeyFormat.ASN);

KeyWorker publicWorker = new KeyWorker(publicKey, KeyFormat.ASN);

System.out.print(privateWorker.decrypt(publicWorker.encrypt("你好！世界")));

System.out.print(publicWorker.decrypt(privateWorker.encrypt("你好！中国")));

//XML

privateWorker = new KeyWorker(xmlKeyPair.getPrivateKey(), KeyFormat.XML);

publicWorker = new KeyWorker(xmlKeyPair.getPublicKey(), KeyFormat.XML);

System.out.print(privateWorker.decrypt(publicWorker.encrypt("你好！世界")));

System.out.print(publicWorker.decrypt(privateWorker.encrypt("你好！中国")));

//PEM

privateWorker = new KeyWorker(pemKeyPair.getPrivateKey(), KeyFormat.PEM);

publicWorker = new KeyWorker(pemKeyPair.getPublicKey(), KeyFormat.PEM);

System.out.print(privateWorker.decrypt(publicWorker.encrypt("你好！世界")));

System.out.print(publicWorker.decrypt(privateWorker.encrypt("你好！中国")));

3.php

4.加解密互通性

任何语言（指的是c#,java,php)使用KeyWorker加密得到的密文，用任何语言的KeyWorker都可以进行解密，只要公私钥配对即可。
