MUltiple Instances of Openvpn and different key sizes

[deleted]

Hello

I would like to know if it would be possible with OpenVPN to set it up allow the use of both 2048 and 4096 key sizes so m users can choose between the two anytime they want speed over security. I am asking this because its common knowledge that a 4096bit key with AES256 encryption is going to pretty much kill your speed.

AFAIK TLS/SSL uses 2048 bit (or 4096) to exchange keys (asymmetric encryption) then they switch over
to symmetric encryption and in your case use AES with 256bit keys.

large keys will make slower the INITIAL handshake only.

am i wrong?
