Simple script for transforming Tunnelblick VPN configuration into OpenVPN configuration.

MakeOVPN.sh

#!/bin/bash
  
# This is just very simple script (No error checking) for transformating the
# tunnelblick VPN configuration with multiple files
# into one file which contains the keys and certs in tags instead of separate file.
# This is good for example for using openVPN in Mobile devices, where you cannot put the Tunnelblick 
# configuration file.

# Usage: 
# - 1. Open terminal and change your directory to 
#      the one containing ca.crt, username.crt, username.key and vpn.whatever.cc.conf
# - 2. Run the script from within, do not forget to add parameter username 
#      (According to this the script knows which files to take and insert into the file...)
#.  3. When done, you will end up with config.ovpn file which contains all the content of files inside tags...

# Note: The awk deletes the paths in the configuration so you do not need to delete them yourself.

# We need to know the username so we get the certificates and key from the files
USERNAME=$1

# We start by deleting the crt/key achieving from files from the configuration
# and insert it into new file config.ovpn
awk '!/crt|key/' *.conf > config.ovpn

# We insert the <ca> tag and keep doing the actions with the other files...
echo "<ca>" >> config.ovpn
cat ca.crt >> config.ovpn
echo "</ca>" >> config.ovpn

# Get the cert...
echo "<cert>" >> config.ovpn
cat  $USERNAME.crt >> config.ovpn
echo "</cert>" >> config.ovpn

# And the key...
echo "<key>" >> config.ovpn
cat  $USERNAME.key >> config.ovpn
echo "</key>" >> config.ovpn
