[root@172-17-218-79 ~]# mkdir cert
[root@172-17-218-79 ~]# cd cert/
[root@172-17-218-79 cert]# openssl genrsa -out server.key 1024
Generating RSA private key, 1024 bit long modulus (2 primes)
......+++++
.........................................+++++
e is 65537 (0x010001)
[root@172-17-218-79 cert]# openssl req -new -key server.key -out server.csr
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:
State or Province Name (full name) [Some-State]:
Locality Name (eg, city) []:
Organization Name (eg, company) [Internet Widgits Pty Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (e.g. server FQDN or YOUR name) []:server
Email Address []:

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
[root@172-17-218-79 cert]# openssl x509 -req -in server.csr -out server.crt -signkey server.key -days 9999
Signature ok
subject=C = AU, ST = Some-State, O = Internet Widgits Pty Ltd, CN = server
Getting Private key
[root@172-17-218-79 cert]# ll
total 12
-rw-r--r-- 1 root root 818 Dec ?6 15:29 server.crt
-rw-r--r-- 1 root root 627 Dec ?6 15:29 server.csr
-rw------- 1 root root 887 Dec ?6 15:28 server.key
?

思路:

1. 生成私钥

2. 生成请求文件

3. 签名+x509封装
