$ gmssl pkcs12 -export  -inkey Medium.key -in MediumCA.crt -out test.pfx -passin  pass:xxx -passout pass:xxx

PKCS转换为PEM
gmssl pkcs12 -in test.pfx -out cert.pem -nodes
转换后可查看证书信息
打印出证书的内容：
gmssl x509 -in cert.pem -noout -text
打印出证书的系列号
gmssl x509 -in cert.pem -noout -s erial
打印出证书的拥有者名字
gmssl x509 -in cert.pem -noout -subject
打印出证书的MD5特征参数
gmssl x509 -in cert.pem -noout -fingerprint
