Mac使用自带OpenSSL生成RSA公钥与私钥_mac 下使用openssl生成rsa公钥和私钥

操作步骤：
1、打开终端，然后输入命令：openssl
2、生成私钥：genrsa -out rsa_private_key.pem 2048
3、私钥转换成PKCS8格式：pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt -out rsa_private_key_pkcs8.pem
4、生成公钥：rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem
5、退出，生成的文件在当前目录：exit

如下操作内容

OpenSSL> genrsa -out rsa_private_key.pem 2048
