# 1.生成长度为1024的RSA密钥对并使用Triple DES算法进行加密
openssl genrsa -des3 -out test-en.key 1024
# 输入密码并验证密码【第2和第3步】都会用到这个密码
Enter pass phrase for test-en.key:
Verifying - Enter pass phrase for test-en.key:

# 2.创建新的证数签名
openssl req -new -key test-en.key -out test.csr
# 输入【第1步的密码】
Enter pass phrase for test-en.key:
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.
-----
# 除 Common Name 外都可为空
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:HN
Locality Name (eg, city) [Default City]:ZZ
Organization Name (eg, company) [Default Company Ltd]:TEST
Organizational Unit Name (eg, section) []:DC
Common Name (eg, your name or your server's hostname) []:192.168.0.1
Email Address []:.
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:.
An optional company name []:.

# 3.去掉密码
openssl rsa -in test-en.key -out test.key
# 输入【第1步的密码】
Enter pass phrase for test-en.key:
writing RSA key

# 4.生成一个自签名的X.509数字证书 有效期365天
openssl x509 -req -days 365 -in test.csr -signkey test.key -out test.crt
# 成功标志
Signature ok
