利用openssl完成X509证书和PFX证书之间的互转

1.将X509格式的数字证书转换成微软的PFX格式

# openssl pkcs12 -export -inkey server.key -in server.crt -out server.pfx

2.将微软的PFX数字证书转换成X509格式

# openssl pkcs12 -in server.pfx -nodes -out server.pem # 生成明文所有内容
# openssl rsa -in server.pem -out server.key # 取 key 文件
# openssl x509 -in server.pem -out server.crt # 取证书
