https自签名证书生成原理

下面是生成自签证书的过程:

1.生成密钥

openssl genrsa -out test.com.key 2048

2.生成证书请求文件,运行之后会出现一大堆要输入的东西,输入之后就生成.csr的文件了

openssl req -new -key test.com.key -out test.com.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) [XX]:CN

State or Province Name (full name) []:Beijing

Locality Name (eg, city) [Default City]:Beijing

Organization Name (eg, company) [Default Company Ltd]:test.com

Organizational Unit Name (eg, section) []:test

Common Name (eg, your name or your server’s hostname) []:www.test.com

Email Address []:root@test.com

Please enter the following ‘extra’ attributes

to be sent with your certificate request

A challenge password []:123456

An optional company name []:test

3.生成证书crt

openssl x509 -req -days 365 -in test.com.csr -signkey test.com.key -out test.com.crt

4.复制文件到相应的目录

cp test.com.crt /etc/pki/tls/certs

cp test.com.key /etc/pki/tls/private/

cp test.com.csr /etc/pki/tls/private/

5.修改配置文件

vim /etc/httpd/conf.d/ssl.conf

SSLCertificateFile /etc/pki/tls/certs/test.com.crt

SSLCertificateKeyFile /etc/pki/tls/private/test.com.key

6.重启apache

service httpd restart

7.这时再使用https访问,查看证书详情的时候就会看到

Issued to: www.test.com

Issued by: www.test.com

颁发者: www.test.com

颁发给: www.test.com

自签名HTTPS证书可以随意签发,没有第三方监督审核,不受浏览器信任,常被用于伪造证书进行中间人攻击,劫持SSL加密流量。很多软件开发商为了节约成本,采用自签名SSL证书,其实是给自己的产品埋下了安全隐患,随时可能被不法份子利用。如果处于成本考虑,建议去GDCA申请免费的HTTPS证书来使用。
