C#.NET 国密SM3 HASH 哈希 与JAVA互通 ver:20230803

 

.NET 环境：.NET6 控制台程序(.net core)。

JAVA 环境：JAVA8，带maven 的JAVA控制台程序。

 

简要解析：

1：明文输入参数都需要string转 byte [] ，要约定好编码，如：UTF8。

2：输出参数：byte [] ，在传输时需要转为string，要约定好编码，如：16进制字符串。

 

.NET 代码：

GmUtil 工具类，需要nuget下载 Portable.BouncyCastle 1.9.0 版本：

 

  1. using Org.BouncyCastle.Asn1;
  2. using Org.BouncyCastle.Asn1.GM;
  3. using Org.BouncyCastle.Asn1.X9;

  15. using System.Collections.Generic;
  16. using System.IO;
  18. namespace CommonUtils
  19. {
  20.     /**
  21.      * need lib:
  22.      * BouncyCastle.Crypto.dll（http://www.bouncycastle.org/csharp/index.html） 
  23.       
  24.      * 用BC的注意点：
  25.      * 这个版本的BC对SM3withSM2的结果为asn1格式的r和s，如果需要直接拼接的r||s需要自己转换。下面rsAsn1ToPlainByteArray、rsPlainByteArrayToAsn1就在干这事。
  26.      * 这个版本的BC对SM2的结果为C1||C2||C3，据说为旧标准，新标准为C1||C3||C2，用新标准的需要自己转换。下面（被注释掉的）changeC1C2C3ToC1C3C2、changeC1C3C2ToC1C2C3就在干这事。java版的高版本有加上C1C3C2，csharp版没准以后也会加，但目前还没有，java版的目前可以初始化时“ SM2Engine sm2Engine = new SM2Engine(SM2Engine.Mode.C1C3C2);”。
  27.      * 
  28.      * 按要求国密算法仅允许使用加密机，本demo国密算法仅供学习使用，请不要用于生产用途。

  4. using Org.BouncyCastle.Utilities.Encoders;
  5. using System.Text;
  8. void TestSM3()

  21.     }
  22. }

JAVA 代码：

maven 引用这2个包。

  1. <dependency>
  2.       <groupId>cn.hutool</groupId>
  3.       <artifactId>hutool-all</artifactId>
  4.       <version>5.8.1</version>
  5.     </dependency>
  6.  
  7.     <dependency>
  8.       <groupId>org.bouncycastle</groupId>
  9.       <artifactId>bcprov-jdk15on</artifactId>
  10.       <version>1.70</version>
  11.     </dependency>

调用：

  1. package org.example;
  3. import cn.hutool.crypto.SmUtil;
  4. import cn.hutool.crypto.asymmetric.KeyType;
  5. import cn.hutool.crypto.asymmetric.SM2;
  6. import org.bouncycastle.crypto.engines.SM2Engine;
  7. import org.bouncycastle.util.encoders.Hex;
  9.     static void testSM3() {
  10.         String content = "1234泰酷拉";
  11.         System.out.println("待处理字符串：" + content);
  13.         String digestHex = SmUtil.sm3(content);
  14.         System.out.println("SM3 HASH后：" + digestHex);
  15.     }
