Keys and certificates for other communicating servers must be created if they do not exist. The following procedure describes the key and certificate generation for host linux.course.test.
# openssl genrsa -out /tmp/linux_key.pem 1024
Generating RSA private key, 1024 bit long modulus
e is 65537 (0x10001)
# openssl req -new -key /tmp/linux_key.pem -out /tmp/linux_req.pem
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) [GB]:DE
State or Province Name (full name) [Berkshire]:Bavaria
Locality Name (eg, city) [Newbury]:Munich
Organization Name (eg, company) [My Company Ltd]:Trend Micro
Organizational Unit Name (eg, section) :Global Training
Common Name (eg, your name or your server's host name) :linux.course.test
Email Address :<Enter>
Please enter the following 'extra' attributes to be sent with your certificate request
A challenge password :<Enter>
An optional company name :<Enter>
After completing this procedure, the /tmp/linux_key.pem file contains the linux.course.test private key in PEM-format. The /tmp/linux_req.pem file contains the unsigned certificate (certificate request) in the PEM-format.
