RSA加解密 Java和C#互通

2018-08-03 17:39 出处:清屏网 人气: 评论(0

使用场景

Java作为服务端生成一对公私钥,C#作为客户端拥有公钥。

RSA算法这里就不多做介绍了,可参考 RSA算法介绍

规范

  • 公私钥的形式都是base64字符串
  • 通过公私钥加密后的字符串也是base64字符串

测试内容

  • C#用公钥加密,Java用私钥解密
  • Java用私钥加密,C#用公钥解密

测试代码

先给出测试代码,后面会有具体的源码。

首先Java作为服务端生成一对公私钥

// 生成一对公私钥
KeyStore keyPair = RSAUtil.createKeys();
System.out.println("公钥:" + keyPair.getPublicKey());
System.out.println("私钥:" + keyPair.getPrivateKey());

公钥

  • C#客户端,通过公钥加密

加密内容: 你好rsa

RSA rsa = new RSA();
string content = "你好rsa";
string pubKey = @"MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCnEqBL90TN2naZicQyik333/BjG/f5Ib7P0n5j3O5IxqJwvISbim5Xg94u3UBmserNYPQWQt1Jb/HiAG5alrnwWB1XypRyyilVsARXblv1AtwG4Y5BWvDG0jsipmRj581TQSd1w2Nq6rw/xzUH2xzUx8MLmoJu1RiC1oCEUx1CgQIDAQAB";

// 公钥加密
string mi = rsa.EncryptByPublicKey(content, pubKey);

得到加密后的字符串(base64格式):

// 解密后的内容
String content = RSAUtil.decryptByPrivateKey(mi, priKey);

System.out.println("你好rsa".equals(content)); // true

至此,公钥加密,私钥解密测试通过。接下来测试Java私钥加密,C#公钥解密
