gmsm

gmsm is an open source pure rust library of China Cryptographic Algorithm Standards.

GM/T Algorithms

• SM2 (GM/T 0003-2012): In the writing...
• SM3 (GM/T 0004-2012): cryptographic hash function with 256-bit digest length.
• SM4 (GM/T 0002-2012): block cipher with 128-bit key length and 128-bit block size, also named SMS4.
