 # gm
-GM sm3/sm2 implement based on OpenSSL
+Implement GM sm3/sm2 based on openssl project.
+The specifications are <<GM/T 0003-2012>> and <<GM/T 0004-2012>>.
+
+You should build your own openssl project, because openssl-devel project 
+installed through yum/apt tool may #defined OPENSSL_NO_EC2M macro, 
+so F2m group is not supported.
+
+In the older version of openssl(before version 1.0.2), there is no funcs 
+to control ECDSA_METHOD struct, so I choose the openssl-1.0.2h version.
