Then introduces an accelerated implementation of the instruction set on x86_64. This optimization supports the four modes of SM4, ECB, CBC, CFB, and CTR. Since CBC and CFB do not support multiple block parallel encryption, the optimization effect is not obvious. And all selftests have passed already. The main algorithm implementation comes from SM4 AES-NI work by libgcrypt and Markku-Juhani O. Saarinen at: https://github.com/mjosaarinen/sm4ni Benchmark on Intel Xeon Cascadelake, the data comes from the mode 218 and mode 518 of tcrypt. The abscissas are blocks of different lengths.
