你好：关于我的一些理解，sm9签名部分秘钥分为四类
1、用户私钥（一串随机数）
2、用户公钥（id）
3、系统私钥（由 系统公钥+id 生成）
4、系统公钥(由 用户私钥 生成)
不知道我上述的理解是否正确，如有错误的地方请指正
疑问点：签名通过系统私钥，验签为什么不通过系统公钥，而是通过用户公钥验证呢？
for(int i=0;i<TEST;i++){// 验证函数
res = SM9_Verify(msg, 20, &sign, &pk, NULL);
if (res) printf("verify error at %d = %d\n", i,res);
}

我看文档上这么写的
func sign (系统参数、签名主公钥Ppub-s、消息M和签名密钥 dsA){}
func verify(系统参数、签名主公钥 Ppub-s、识别符 hid、标识 IDA、消息 M’及其数字签名(h’, S’)){}
虽然在 SM9_FREE里 签名、验签方法参数都未传入 “签名主公钥Ppub-s” 这个参数
但我看到了 在“签名方法”中在内部对该参数“签名主公钥Ppub-s”进行了生成
然而“验签方法”中好像未提及该参数“签名主公钥Ppub-s”

---------------------
我的理解是这样子
但是在验签部分为看到出现 “签名主公钥” 不知道是封装在哪里了

在代码中，签名主公钥被init函数作为系统参数做全局存储了。

应该是在 SM9_Set_Sign 函数内设置的。
类似的还有SM9_Set_Encrypt，SM9_Set_KeyExchange。
具体使用可以参考sm9_algorithm.h头文件

博主，你好，我如果只拿到了如下值我应该如何做验签呢，能否给我一些思路

* @param signature 签名值
* @param data 待签数据
* @return true-验签成功；false-验签失败

你这个主秘钥是公钥吧？
启动一下签名lib
SM9_Set_Sign(mspk.x1, mspk.x2, mspk.y1, mspk.x2, NULL);
就可以调用
SM9_Verify(msg, 20, &sign, &pk, NULL);
完成验签了

是的 系统主公钥，我刚刚也是这么操作的 但是验签失败 不知道是否是我哪里操作不对

博主你好，我已反复试验多次，还是不行，不知是否是其他问题
SM9_Init(0,0,32,NULL,NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL );
gg = SM9_Set_Sign(mspk.x1, mspk.x2, mspk.y1, mspk.x2, NULL); // 启动签名lib
SM9_Set_Sign(NULL, NULL, NULL, NULL, gg);
SM9_Verify(msg, 20, &sign, &pk, NULL);

我更新了代码，修复了一个BUG。
关于验证，可以参考SM9Test.c中的”独立验证“部分。
单独运行该部分也是能够正确验证的。
顺序
SM9_Init(0,0,32,NULL,NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL );
gg = SM9_Set_Sign(mspk.x1, mspk.x2, mspk.y1, mspk.y2, NULL); // 启动签名lib
SM9_Verify(msg, 20, &sign, &pk, NULL);
我使用自己随机生成的签名能通过验证。但是你的数据无法正确通过验证。

原先的SM9Test.c 里面gg = SM9_Set_Sign(mspk.x1, mspk.x2, mspk.y1, mspk.2, NULL); 传入参数有误，应该分别传入mspk的 x1 x2 y1 y2 ，请仔细检查
请参考我最新的SM9Test.c
SM9_Set_Sign(NULL, NULL, NULL, NULL, gg)函数需要要求gg返回不是NULL才能继续执行。
