I'm having a hard time knowing whether the following setup is vulnerable to CRIME/BREACH type attacks (which target HTTPS).
I am running a Wireguard VPN that tunnels VXLAN protocol, using ChachaPoly20 encryption. I would like to add CPU cheap compression (LZ4) on the VXLAN frames (RFC3173 likewise).
Would the fact that I add LZ4 on my VXLAN frames make the encrypted VPN tunnel vulnerable to a potential attacker?
Side question: Since CRIME and BREACH target HTTPS specifically, are there any more generic versions of those attacks?
