Embedding certificates in .ovpn

You can simplify OpenVPN distribution by only use one file for both config and certificates. A normal .ovpn file with separate .key and .crt files looks like this.

client dev tun 
dev-node Dalesjo VPN 
proto tcp 
remote my-server 443 
resolv-retry infinite 
nobind 
persist-key 
persist-tun 
remote-cert-tls server 
verb 3 
comp-lzo yes

ca DALESJO-OpenVPN.crt
cert DALESJO-SADAL.crt
key DALESJO-SADAL.key
tls-auth DALESJO-Server.tls 1

A combined .ovpn file looks like this

client
dev tun
dev-node Dalesjo VPN
proto tcp
remote my-server 443
resolv-retry infinite
nobind
persist-key
persist-tun
remote-cert-tls server
verb 3
comp-lzo yes
<ca>
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
</ca>
<cert>
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
</cert>
<key>
-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----
</key>

key-direction 1
<tls-auth> 
 #
 # 2048 bit OpenVPN static key
 #
 -----BEGIN OpenVPN Static key V1-----
 ...
 -----END OpenVPN Static key V1-----
</tls-auth>
