 The files for a certificate/key pair have to be named `cert.der` and `key.der` respectively. The certificate has to be a X.509 certificate in a DER format file and has to include a subject alt name of the domain name. The private key has to be in DER format and must be either an RSA, ECDSA or Ed25519 key.
