You can find a number of SM2 implementations on github, etc. https://github.com/openssl/openssl/blob/9453b196343db579c590130adc63d35d2ff87188/crypto/sm2/sm2_crypt.c https://github.com/ARMmbed/mbedtls/blob/3ea8c4cb2a03724ba15c915e02d83255e1884859/library/ecdsa.c https://github.com/developerworks/sm2/blob/master/miracl/sm2.c Asymmetric ciphers are typically not "library free", because you need the big number operations. The big number operations should preferably secure versions that don't reveal private key through side-channels (timing etc), so these operations are usually are provided by a cryptographic library.
