Answer : How do i create additional client key pairs?

Creating Additional VPN Clients

You will need a copy of three files, the certificate authority key and certificate (ca.key and ca.crt) and a .ovpn configuration file. These were created during the server-side setup of your VPN.

Open a command prompt and change directories to C:\Program Files\OpenVPN\easy-rsa. From the command prompt type the following command: init-config. It should look like this:

C:\Program Files\OpenVPN\easy-rsa>init-config

C:\Program Files\OpenVPN\easy-rsa>copy vars.bat.sample vars.bat
1 file(s) copied.

C:\Program Files\OpenVPN\easy-rsa>copy openssl.cnf.sample openssl.cnf
1 file(s) copied.

Then edit the newly created vars.bat at the bottom so that it matches your server's information.

set KEY_COUNTRY=(2 character country code)
set KEY_PROVINCE=(2 character state or province code)
set KEY_CITY=(your city or locality)
set KEY_ORG=(your company or organization name)
set KEY_EMAIL=(your organization's email address)

If you're not sure what to set these values to, open the ca.crt file, click the details tab, and then click on issuer. C=Country, S=State/Province, L=City, O=Org, and E=Email. Note: you only need to do the above for the first client you add. After that there is no need to run init-config or edit vars.bat.

Now return to the command prompt and type the following commands:

C:\Program Files\OpenVPN\easy-rsa>vars

C:\Program Files\OpenVPN\easy-rsa>clean-all
1 file(s) copied.
1 file(s) copied.

This will create a directory called C:\Program Files\OpenVPN\easy-rsa\keys. Copy the ca.crt and ca.key files into this directory.

Return to the command line and issue the following commands:

C:\Program Files\OpenVPN\easy-rsa>vars

C:\Program Files\OpenVPN\easy-rsa>build-key.bat client1 (where “client1” is a unique client name for your VPN)

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.
