补上一课，RSA命令行生成不同格式的秘钥。

RSA秘钥分为PKCS#8和PKCS#1

1.生成PEM格式的私钥，默认格式是PKCS#1

openssl genrsa -out private.pem 2048

PKCS#1记住格式的关键词 Begin RSA private key + End RSA private key

openssl生成rsa密钥对,Openssl,服务器,linux,运维

2.由私钥推出公钥

openssl rsa -in private.pem -pubout -out public.pem

PKCS#1转为为PKCS#8格式，使用命令行：openssl pkcs8 -topk8 -inform PEM -in private.pem -outform PEM -nocrypt > private_pkcs8.pem

PKCS#8记住格式的关键词 Begin private key + End private key

openssl生成rsa密钥对,Openssl,服务器,linux,运维

转为为PKCS#1格式，使用命令行：

3.查看私钥内部的模数指数

openssl rsa -in private.pem 2048 -text -noout

第三步运行的结果如下所示：
