+ SM4 cipher algorithms (OSCCA GB/T 32907-2016) (x86_64/AES-NI/AVX2).
+
+ SM4 (GBT.32907-2016) is a cryptographic standard issued by the
+ Organization of State Commercial Administration of China (OSCCA)
+ as an authorized cryptographic algorithms for the use within China.
+
+ This is SM4 optimized implementation using AES-NI/AVX2/x86_64
+ instruction set for block cipher. Through two affine transforms,
+ we can use the AES S-Box to simulate the SM4 S-Box to achieve the
+ effect of instruction acceleration.
+
+ If unsure, say N.
