VPN connection using TLS protocol with openVPN


I send a request in my university to have access through VPN and through the manual they provide i add in the firefox my personal certificate and then download it as a .p12 file.

Now i want to use this file to connect through the vpn but im little confused.
All tutorials i saw in internet in the config file of openvpn used .crt and .key files for ca , cert and key directives. Also i have to use and a .key file for the TLS connection but cannot understand where to find it (for tls-auth directive).

The only files that i have are the RootCA.pem (University's public key) and the cert.p12 that i've got from firefox.

Can someone give a hint on how to achieve a connection on the VPN?

Thanks in advance!

Ok. Finally i used these commands and all works fine now.

To extract the CA Certificate:
openssl pkcs12 -in myvpn.p12 -cacerts -nokeys -out myvpnca.pem

To extract the Personal Certificate:
openssl pkcs12 -in myvpn.p12 -clcerts -nokeys -out myvpncert.pem

To extract the Private Key:
With a password: openssl pkcs12 -in mydccert.p12 -clcerts -nocerts -out myvpnkey.pem
Without a password: openssl pkcs12 -in mydccert.p12 -clcerts -nocerts -nodes -out myvpnkey.pem
