What Protocol/Encryption Should I Use?

OpenVPN is the best choice when available on your device. It’s easy to check that your VPN provider is using strong encryption algorithms and keys (like 256bit keys and AES encryption) by looking at the OpenVPN configuration files supplied by your VPN provider. OpenVPN is slightly more effort to setup (download and install a client for Windows, OS X, IOS 5+ & Android 4+) but it should be the default way for most people to connect to their VPN. We have been using OpenVPN securely (2048 bit RSA keys and AES-256) since our beginning in 2009 so previous traffic should still be secure from decryption. In 2014 we upgraded to 4096 but RSA keys.

L2TP/IPSec is a good choice if you want a quick and easy setup. However the encryption algorithms and keys used depend on your VPN provider and your device, and it is difficult to know if secure or insecure encryption is being used. Your data could be encrypted with AES-256 (more secure) or with 3DES (not secure) and you wouldn’t know. An evil or silly VPN provider could force all clients to use 3DES. Also Windows XP does not support AES and would use 3DES encryption instead.

PPTP has known security weaknesses and should only be used as last option or where nothing else works with your device. There are no good reasons to use PPTP unless IPSec traffic is being blocked and you cannot install openVPN on your device. We would recommend only use PPTP if your security and privacy are not a concern – for example if you just want to access websites or content blocked in your country.
