> 方式一
- [生成密钥](https://opendocs.alipay.com/open/291/105971)
> 方式二
- 生成私钥 : openssl genrsa -out rsa_private_key.pem 1024
- 根据私钥生成公钥: openssl rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem
- 私钥转化成pkcs8格式: openssl pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt > rsa_private_key_pkcs8.pem
