* **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。

* **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。
