OpenVPN .ovpn manipulation.

This is how you can take an OpenVPN .ovpn config file and extract the certificates/keys required to import the profile into NetworkManager.

• Download the .ovpn file. Save it somewhere you can store it permanently (I use ~/.vpn).
• Copy from between <ca> tags into ca.crt, remove <ca> tags.
• Copy from between <cert> tags into client.crt, remove <cert> tags.
• Copy from between <key> tags into client.key, remove <key> tags.
• Copy from between <tls-auth> tags into ta.key, remove <tls-auth> tags.
• Remove the line "key-direction 1"
• Above "# -----BEGIN RSA SIGNATURE-----" insert the following lines.

Docker's Remote API can be secured via TLS and client certificate verification.
First of all you need a few certificates and keys:

• CA certificate
