## Packages ## Packages
- **SM2** - This is a SM2 sm2p256v1 implementation whose performance is similar like golang native NIST P256 under **amd64** and **arm64**, for implementation detail, please refer [SM2实现细节](https://github.com/emmansun/gmsm/wiki/SM2%E6%80%A7%E8%83%BD%E4%BC%98%E5%8C%96). It supports ShangMi sm2 digital signature, public key encryption algorithm and also key exchange. - **SM2** - This is a SM2 sm2p256v1 implementation whose performance is similar like golang native NIST P256 under **amd64**, **arm64** and **s390x**, for implementation detail, please refer [SM2实现细节](https://github.com/emmansun/gmsm/wiki/SM2%E6%80%A7%E8%83%BD%E4%BC%98%E5%8C%96). It supports ShangMi sm2 digital signature, public key encryption algorithm and also key exchange.
- **SM3** - This is also a SM3 implementation whose performance is similar like golang native SHA 256 with SIMD under **amd64** and **arm64**, for implementation detail, please refer [SM3性能优化](https://github.com/emmansun/gmsm/wiki/SM3%E6%80%A7%E8%83%BD%E4%BC%98%E5%8C%96). It also provides A64 cryptographic instructions SM3 tested with QEMU. - **SM3** - This is also a SM3 implementation whose performance is similar like golang native SHA 256 with SIMD under **amd64** and **arm64**, for implementation detail, please refer [SM3性能优化](https://github.com/emmansun/gmsm/wiki/SM3%E6%80%A7%E8%83%BD%E4%BC%98%E5%8C%96).

## 包结构 ## 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。 - **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**，**arm64**和**s390x**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。 - **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。
