Se la chiave è generata con questo comando openssl req -new -x509 -keyout key.pem -out crt.pem la chiave privata è cifrata e serve passare il parametro passphrase specificando la password fornita.

const server =  createServer({
    minVersion: 'TLSv1',
    key:  readFileSync('./key.pem', 'utf8'),
    cert: readFileSync('./crt.pem', 'utf8'),
    ca: 'X509 CERTIFICATE',
    passphrase: 'hello'
});

aggiungendo l'opzione -nodes in fondo non è più necessario (openssl req -new -x509 -keyout key.pem -out crt.pem -nodes)
