SM3 - Cryptographic Hash Algorithm

The algorithm is defined by GB/T 32905-2016.

The gmcrypto/sm3 package implements

• hash.Hash, which can be further used in HMAC or KDF.
• encoding.BinaryMarshaler and encoding.BinaryUnmarshaler, which implies that this SM3 implementation is resumable, and its state can be encoded to or decoded from a JSON object.

SM4 - Block Cipher Algorithm

The algorithm is defined by GB/T 32907-2016.

The gmcrypto/sm4 package implements

• crypto/cipher.Block, which can be further used in GCM, CBC, CFB, CTR, OFB, and many other block cipher modes.
