openvpn-certgen

openvpn-certgen.pl is a self-signed certificate generator tool, used for OpenVPN. It covers multiple functions to get up a running OpenVPN installation on server and on client systems.

The script is able to install required packages and tools to set up an OpenVPN server. This is done automatically if the script is started and the required tools are not found. For each client a zip file will be created with Windows and Linux data. This allows a convenient handling of different client certificates.

Currently supported client systems are Windows and Linux (Debian, Mint, Ubuntu).

Example usages

• First start of this script

   # openvpn-certgen.pl  -t /tmp/etc/openvpn   		# run as root !
  

  This prepares the required packages and tools to generate certificates.

• Adjust config-file

  The config with default data needs to be adjusted with real data.

• Make client certificate

   $ openvpn-certgen.pl -t /tmp/etc/openvpn client1
  

  Creates a test environment to play with the server certificate and a client certificate for client1.

• More client certificates

   $ openvpn-certgen.pl -t /tmp/etc/openvpn client1 client2 clinet3
  

  Creates certificate for client2, client3. client1 will be ignored, a certificate is already existing.

• Configuration for working environment

  Next call is used if real certificates are required. The rest is working as in the examples above.

   # openvpn-certgen.pl  			 		# root !
  

  This is used to create certificates under real conditions.
