ProtonVPN directions for configuring WireGuard on a Mikrotik router include statement that "Your WireGuard private key ... can be found by opening the configuration file ..." downloaded from the ProtonVPN site. However, when I look at the WireGuard config file that I downloaded from the ProtonVPN site, the config file does not include an actual private key string. Instead the ProtonVPN WireGuard config file includes what looks like a masked string "*****" [See below]. So the question for me is how I determine the private key string that I should be inputting via CLI when configuring a Mikrotik router to use the ProtonVPN Wireguard protocol. Helpful tips and suggestions much appreciated.
For reference, I have attached a copy of the ProtonVPN directions for configuring WireGuard on a Mikrotik router (or at least what think are the correct directions). And below is a copy of the related config file that I downloaded from the ProtonVPN website that includes the public key to use, but not the private key.
