openssl的版本如下：

SM3使用实例

SM3是中华人民共和国政府采用的一种密码散列函数标准，由国家密码管理局于2010年12月17日发布。相关标准为“GM/T 0004-2012 《SM3密码杂凑算法》”。

1. SM3的扎凑实例

echo "adsfad" > plain.dat
openssl sm3 plain.dat

SM2使用实例

1. 生成SM2密钥对

 openssl ecparam -genkey -name SM2 -out sm2keypair.pem -text

2.查看SM2密钥对

openssl ecparam -in sm2keypair.pem -text

3.生成自签名证书

 openssl req -x509 -key sm2keypair.pem -subj "/C=CN/ST=BJ/L=BJ/O=HD/OU=dev/CN=hello/emailAddress=hello@world.com" -out sm2cert.pem

4.查看证书详情

openssl x509 -in sm2cert.pem -text

执行结果如下：
