# 第一步：制作服务器证书

#

 

brm-debian:~# openssl genrsa -des3 -out server.key 1024

Generating RSA private key, 1024 bit long modulus
.++++++
............++++++
e is 65537 (0x10001)
Enter pass phrase for server.key:
Verifying - Enter pass phrase for server.key:

brm-debian:~# openssl req -new -key server.key -out server.csr
Enter pass phrase for server.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.
-----
Country Name (2 letter code) [AU]:CN
State or Province Name (full name) [Some-State]:Beijing
Locality Name (eg, city) []:Xicheng
Organization Name (eg, company) [Internet Widgits Pty Ltd]:baomi
Organizational Unit Name (eg, section) []:dev
Common Name (eg, YOUR name) []:JLB
Email Address []:

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:hello
An optional company name []:

# 第二步：制作客户端证书

#

 

brm-debian:~# openssl genrsa -des3 -out client.key 1024
Generating RSA private key, 1024 bit long modulus
....................++++++
..............++++++
e is 65537 (0x10001)
Enter pass phrase for client.key:
Verifying - Enter pass phrase for client.key:

brm-debian:~# openssl req -new -key client.key -out client.csr
Enter pass phrase for client.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.

State or Province Name (full name) [Some-State]:Beijing
Locality Name (eg, city) []:Xicheng
Organization Name (eg, company) [Internet Widgits Pty Ltd]:baomi
Organizational Unit Name (eg, section) []:dev
Common Name (eg, YOUR name) []:JLB
Email Address []:

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:hello
An optional company name []:

 

 

#

# 第三步：生成CA证书

#

 

brm-debian:~# openssl req -new -x509 -keyout ca.key -out ca.crt
Generating a 1024 bit RSA private key
...........++++++
.............................................++++++
writing new private key to 'ca.key'
Enter PEM pass phrase:
Verifying - Enter PEM pass phrase:
-----
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]:CN
State or Province Name (full name) [Some-State]:Beijing
Locality Name (eg, city) []:Xicheng
Organization Name (eg, company) [Internet Widgits Pty Ltd]:baomi
Organizational Unit Name (eg, section) []:dev
Common Name (eg, YOUR name) []:JLB
Email Address []:

# 第四步：对证书签名

brm-debian:~# chmod -R 777 demoCA/
brm-debian:~# openssl ca -in server.csr -out server.crt -cert ca.crt -keyfile ca.key
Using configuration from /usr/lib/ssl/openssl.cnf
Enter pass phrase for ca.key:
