mkdir -p ~/.pip
touch ~/.pip/pip.conf
vi ~/.pip/pip.conf

[global]
trusted-host=mirrors.aliyun.com
index-url=http://mirrors.aliyun.com/pypi/simple/

安装easy_gmssl

安装依赖
dnf install -y gcc cmake
安装easy_gmssl库
pip3 install easy_gmssl

安装GmSSL 3.1.1

tar -zxvf GmSSL-3.1.1.tar.gz

cd GmSSL-3.1.1
mkdir build
cd build
cmake ..
make
make install

vi /etc/ld.so.conf，添加一行：
/usr/local/lib
加载动态链接
ldconfig

验证版本
gmssl version

生成公钥和私钥
gmssl sm2keygen -pass 123456 -out sm2_private.pem -pubout sm2_public.pem
