## 包结构
* **SM2** - SM2椭圆曲线公钥密码算法，曲线的具体实现位于[internal/sm2ec](https://github.com/emmansun/gmsm/tree/main/internal/sm2ec) package中。SM2曲线实现性能和Golang SDK中的NIST P256椭圆曲线原生实现（非BoringCrypto）类似，也对**amd64** 和 **arm64**架构做了专门汇编优化实现，您也可以参考[SM2实现细节](https://github.com/emmansun/gmsm/wiki/SM2%E6%80%A7%E8%83%BD%E4%BC%98%E5%8C%96)及相关Wiki和代码，以获得更多实现细节。SM2包实现了SM2椭圆曲线公钥密码算法的数字签名算法、公钥加密算法、密钥交换算法，以及《GB/T 35276-2017信息安全技术 SM2密码算法使用规范》中的密钥对保护数据格式。
* **SM3** - SM3密码杂凑算法实现。**amd64**下分别针对**AVX2+BMI2、AVX、SSE2+SSSE3**做了消息扩展部分的SIMD实现； **arm64**下使用NEON指令做了消息扩展部分的SIMD实现，同时也提供了基于**A64扩展密码指令**的汇编实现。您也可以参考[SM3性能优化](https://github.com/emmansun/gmsm/wiki/SM3%E6%80%A7%E8%83%BD%E4%BC%98%E5%8C%96)及相关Wiki和代码，以获得更多实现细节。
* **SM4** - SM4分组密码算法实现。**amd64**下使用**AES**指令加上**AVX2、AVX、SSE2+SSSE3**实现了比较好的性能。**arm64**下使用**AES**指令加上NEON指令实现了比较好的性能，同时也提供了基于**A64扩展密码指令**的汇编实现。针对**ECB/CBC/GCM/XTS**加密模式，做了和SM4分组密码算法的融合汇编优化实现。您也可以参考[SM4性能优化](https://github.com/emmansun/gmsm/wiki/SM4%E6%80%A7%E8%83%BD%E4%BC%98%E5%8C%96)及相关Wiki和代码，以获得更多实现细节。
* **SM9** - SM9标识密码算法实现。基础的素域、扩域、椭圆曲线运算以及双线性对运算位于[bn256](https://github.com/emmansun/gmsm/tree/main/sm9/bn256)包中，分别对**amd64**、**arm64**架构做了优化实现。您也可以参考[SM9实现及优化](https://github.com/emmansun/gmsm/wiki/SM9%E5%AE%9E%E7%8E%B0%E5%8F%8A%E4%BC%98%E5%8C%96)及相关讨论和代码，以获得更多实现细节。SM9包实现了SM9标识密码算法的密钥生成、数字签名算法、密钥封装机制和公钥加密算法、密钥交换协议。
* **ZUC** - 祖冲之序列密码算法实现。使用SIMD、AES指令以及无进位乘法指令，分别对**amd64**、**arm64**架构做了优化实现, 您也可以参考[ZUC实现及优化](https://github.com/emmansun/gmsm/wiki/Efficient-Software-Implementations-of-ZUC)和相关代码，以获得更多实现细节。ZUC包实现了基于祖冲之序列密码算法的机密性算法、128/256位完整性算法。
* **CFCA** - CFCA特定实现，目前实现的是SM2私钥、证书封装处理，对应SADK中的**PKCS12_SM2**。
* **CIPHER** - ECB/CCM/XTS/HCTR/BC/OFBNLF加密模式实现。XTS模式同时支持NIST规范和国标 **GB/T 17964-2021**。当前的XTS模式由于实现了BlockMode，其结构包含一个tweak数组，所以其**不支持并发使用**。**分组链接（BC）模式**和**带非线性函数的输出反馈（OFBNLF）模式**为分组密码算法的工作模式标准**GB/T 17964**的遗留模式，**带泛杂凑函数的计数器（HCTR）模式**是**GB/T 17964-2021**中的新增模式。分组链接（BC）模式和CBC模式类似；而带非线性函数的输出反馈（OFBNLF）模式的话，从软件实现的角度来看，基本没有性能优化的空间。
* **SMX509** - Go语言X509包的分支，加入了商用密码支持。
* **PADDING** - 一些填充方法实现（非常量时间运行）：**pkcs7**，这是当前主要使用的填充方式，对应**GB/T 17964-2021**的附录C.2 填充方法 1；**iso9797m2**，对应**GB/T 17964-2021**的附录C.3 填充方法 2；**ansix923**，对应ANSI X9.23标准。**GB/T 17964-2021**的附录C.4 填充方法 3，目前没有实现，它对应ISO/IEC_9797-1 padding method 3，如有使用需求，可以考虑实现。
* **PKCS7** - [mozilla-services/pkcs7](https://github.com/mozilla-services/pkcs7) 项目的分支，加入了商用密码支持。
* **PKCS8** - [youmark/pkcs8](https://github.com/youmark/pkcs8)项目的分支，加入了商用密码支持。
* **ECDH** - 一个类似Go语言中ECDH包的实现，支持SM2椭圆曲线密码算法的ECDH & SM2MQV协议，该实现没有使用 **big.Int**，也是一个SM2包中密钥交换协议实现的替换实现（推荐使用）。
* **DRBG** - 《GM/T 0105-2021软件随机数发生器设计指南》实现。本实现同时支持**NIST Special Publication 800-90A**（部分） 和 **GM/T 0105-2021**，NIST相关实现使用了NIST提供的测试数据进行测试。本实现**不支持并发使用**。

* **[Trisia/Randomness](https://github.com/Trisia/randomness)** - 一个Go语言随机性检测规范实现。
* **[PKCS12](https://github.com/emmansun/go-pkcs12)** - [SSLMate/go-pkcs12](https://github.com/SSLMate/go-pkcs12)项目的一个分支，加入了商用密码支持，由于PKCS12标准比较老，安全性不高，所以以独立项目进行维护。
* **[MKSMCERT](https://github.com/emmansun/mksmcert)** - 一个用于生成SM2私钥和证书的工具，主要用于开发测试，它是[FiloSottile/mkcert](https://github.com/FiloSottile/mkcert)项目的一个分支，加入了商用密码支持。
