 The OpenSSL integrated with Chinese national cryptography standard:
 
- * SM2: Elliptic curve cryptography, including signature scheme, encryption and key agreement.
- * SM3: Hash algorithm with 256-bit digest length.
- * SM4: or SMS4, a Feistel-style block cipher with 128-bit key length and 128-bit block size.
-
-The first release only add SM2 signature scheme, which modify the ECDSA implementation of OpenSSL.
-In the future release the SM2 will be changed to stand alone METHOD modules.
-SM3 will be provided as a EVP_MD() module and SM4 will be provided as multiple EVP_CIPHER() modules.
+ * SM2: Elliptic curve cryptography, including signature scheme, encryption and key agreement, use the modified `ECDSA` module.
+ * SM3: Hash algorithm with 256-bit digest length, use `EVP_sm3()`
+ * SM4: or SMS4, a Feistel-style block cipher with 128-bit key length and 128-bit block size, use `EVP_sms4_ecb()`, `EVP_sms4_cbc()`, `EVP_sms4_cfb()`, `EVP_sms4_ofb()`.
