Since there is an "RSA privsep engune" and no "ECDSA privsep engine" I guess
this is not supported.

You can do this easily with nginx or I think also haproxy.

relayd and EC tls - key size 832 is not supported

2021-04-05 Thread Chris Narkiewicz 
Hi,

I'm configuring relayd to run grafana vhost (grafana does not
support FastCGI).

My relayd.conf is:

http protocol "www" {
match request header "Host" value "grafana.mydomain.net" forward to 
tls keypair grafana.mydomain.net
}

relay "www" {
listen on wg0 port 443 tls
protocol www
forward to  port 3000
}
# end if relayd.conf

TLS certificate has been generated using easyrsa, and it uses EC algo
with secp384r1 curve.

When I start relayd, it complains about unsupported key size:

ca_engine_init: using RSA privsep engine
...
ssl_ctx_fake_private_key: key size 832 not support


When I use RSA certificate generated using Let's Encrypt, it works.
Does it support EC? Am I doing something wrong?
