- Removed "fast" and "slow" mode (not a good idea, I prefer to give the choice for the parameters directly)
- Corrected some confusion between the cipher for the data channel and the control channel, my bad.
- using TLS-DHE-RSA-WITH-AES-256-GCM-SHA384 by default for the control channel
- using SHA384 by default for HMAC auth and RSA certificate
- giving the choice for the cipher of the data channel, the size of the DH key and the RSA Key
I will explain all my choices here : https://github.com/Angristan/OpenVPN-install#encryption (likely tomorrow)
There is now the choice to use TCP or UDP for OpenVPN protocol. You should always use UDP, but TCP can be useful sometimes : on lossy networks or to bypass some blockage
