# 1. sm2_sm3_sm4
本地安装 SM2-SM3-SM4.jar
```xml
<!-- 国密加解密-->
<dependency>
	<groupId>com.yl</groupId>
	<artifactId>SM2-SM3-SM4</artifactId>
	<version>1.0.0</version>
</dependency>
<dependency>
	<groupId>org.bouncycastle</groupId>
	<artifactId>bcprov-jdk15on</artifactId>
	<version>1.60</version>
</dependency>
```
my内是把jar内SM2,SM3,SM4代码提取出来实现的，这样不用安装本地jar了

# 2. SM2-SM3-SM4加解密-vue
 前端同样实现 SM2,SM3,SM4
# 3. 测试
```java
String key = "1234567812345678";
String plntxt = 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";

String s = SM4Util.decryptBody(plntxt, key);
System.out.println(s);
JSONObject jsonObject = JSON.parseObject(s, Feature.OrderedField);
String verifyStr = jsonObject.getString("verify");
String dataStr = jsonObject.getJSONObject("data").toJSONString();

boolean b = SM2.verifySign(dataStr, verifyStr, "BPMd9m9FMeBmWatnMMdcafiAJCBmGVlrw1MRor7iRmytIN6ilcCKZnnDBb6XSqPV4tuai1nYrfg3SFTJAPmCKME=");
System.out.println(b);

这里虽然实现了SM2,SM3.SM4,但是SM2加解密和加签验签和前端实现的SM2不兼容，第一步中的可以完美实现前后端匹配
