#### Diffie-Hellman Groups
Diffie-Hellman groups are enabled by default, with a pregenerated key in `/etc/nginx/dhparam.pem`.
Diffie-Hellman groups are enabled by default, with a pregenerated key in `/etc/nginx/dhparam/dhparam.pem`.
You can mount a different `dhparam.pem` file at that location to override the default cert.
To use custom `dhparam.pem` files per-virtual-host, the files should be named after the virtual host with a
`dhparam` suffix and `.pem` extension. For example, a container with `VIRTUAL_HOST=foo.bar.com`
should have a `foo.bar.com.dhparam.pem` file in the `/etc/nginx/certs` directory.
> NOTE: If you don't mount a `dhparam.pem` file at `/etc/nginx/dhparam/dhparam.pem`, one will be generated
at startup. Since it can take minutes to generate a new `dhparam.pem`, it is done at low priority in the
background. Once generation is complete, the `dhparams.pem` is saved on a persistent volume and nginx
is reloaded. This generation process only occurs the first time you start `nginx-proxy`.
#### Wildcard Certificates
Wildcard certificates and keys should be named after the domain name with a `.crt` and `.key` extension.
